2 8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene “Palaeoentomology”: An advanced traditional science dealing with the past with modern technologies

Palaeoentomology began formally in the late XVIIIth Century with publications on fossil insects in amber. At the start of the XIXth Century, the first studies and descriptions of insects from sedimentary rocks appeared. This discipline then developed during the XIXth and beginning of the XXth centuries, and resulted in works and reviews. The end of the XXth and the beginning of XXIst centuries (especially after the famous film “ Park,” produced by Steven Spielberg in 1993 and based on the eponymous novel of Michael Crichton, together with the discovery of new rock and amber outcrops with fossil insects of different geological ages in various parts of the world), witnessed a significant and exponential growth of the science of palaeoentomology resulting in a huge amount of high- quality international scientific work, using the most advanced analytical, phylogenetic and imaging techniques. Today our discipline is undergoing a wonderful intellectual radiation. Studies and understanding of phylogenetic relationships between insects and other terrestrial arthropods cannot ignore their fossil record, their palaeodiversity and palaeodistributions. Recent progress in knowledge of fossil insects improves our understanding of the real effects of global historical and biological crises; and brings to light the evolutionary scenarios of different entomological shaped over geological times.

The growing interest in palaeoentomology and its globalization brought about the formation of several serious multidisciplinary and collaborative scientific teams, and now with the present technologies of communication, most of the scientists from all over the world are collaborating in international teams without regard to distance or location. The spirit of international collaboration resulted in the creation of our society, IPS, which was born in 2001 in Krakow (Poland) and officially registered on the 1st of October 2015 in Paris ().

Today we are holding our 8th x3 congress in the Dominican Republic, after several previous congresses (2016 in Edinburgh, Scotland,

8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene 3 where ‘International Fossil Insects Day’ was declared and is now celebrated on each first of October; 2013 in Byblos, Lebanon; 2010 in Beijing, ; 2007 in Vitoria-Gasteiz, Basque region, ; 2005 in Pretoria, South , where Fossils x3 [congress on Fossil Insects, Arthropods and Amber] was initiated by merging three congresses [Palaeoentomological Conference, World Congress on Amber Inclusions, and International Meeting on Palaeoarthropodology]; 2001 in Krakow, Poland; 2000 in Ribeirão Preto, ; 1998 in Vitoria-Gasteiz, Basque region, Spain; 1998, in Moscow, ). Prior to these congresses there was the creation of the Fossil Network (1996) in Strasbourg, France, under the auspices of the European Science Foundation.

Following 1996, there were several unsuccessful attempts to have a specialized scientific journal for our discipline, and today, with the significant growing numbers of publications on fossil terrestrial arthropods and amber, there has been an urgent need and challenge to create the official journal of the IPS as a specialized high-quality platform to bring together recent research and discoveries in our field in an expedited manner. Consequently, with the mutual efforts of IPS Executive Board members and Professor Diying Huang from the Nanjing Institute of Geology and Palaeontology, we have succeeded after long-term negotiations with several publishers to reach an agreement with Magnolia Press to create “Palaeoentomology” in late 2018. Today we are working on our third issue of this journal, to which we hope and wish for continued success.

I sincerely believe that scientific research on fossil insects and amber will continue to increase and prosper in the future. I am quite sure that significant and surprising results will emerge globally in tandem, and I wish great prosperity to our society.

Amber from the Early to Middle of the Dominican Republic contains a rich paleobiota of extant genera that presently live in tropical Mesoamerica and/or , from fungi to vascular and non- vascular , worms, gastropods, small (lizards, frogs, feathers, mammalian remains), and especially terrestrial arthropods. Preservation in this amber is also consistently the finest among all . Some examples of distinctly neotropical taxa are provided, including the Hymenaea, the source genus of that produced the amber, among others. By the time of amber formation, however, there were also significant numbers of extralimital taxa, whose closest living relatives occur only on the Central American mainland, or even in the Old World. Some examples are discussed, including stingless (Meliponinae), certain , , , and , among others. These Caribbean reveal some fundamental aspects of the assembly of biological communities: 1. There has been stasis of neotropical forests since at least the Miocene and probably much earlier; 2. There has been dramatic loss of certain genera from a region or even continents, while the rest of the community persisted; 3. Some of the lost taxa were quite common, possibly even ecologically dominant; 4. Lost taxa may represent standard turnover in communities, or represent special circumstances (due perhaps to an increasingly insular Hispaniola). The age of an amber deposit does not dictate its scientific significance; in the case of Dominican amber it provides rare insight into the stasis and of the most biotically diverse type of ecosystem on .

The age and origin of Dominican Republic amber has long been a subject of great interest to paleobiologists and evolutionary biologists because of the high quality and diversity of fossil inclusions in this mineral. In addition to its nonbiological content, which includes water, gases, and a variety of organic compounds, Dominican ambers include fungi, plants, , , and vertebrates representative of the of the ancient insular tropical forests in which they lived. Efforts continue to extract endogenous DNA from such inclusions; despite early claims, however, there have to date been no accepted successes. Proteins are another possibility, and research in this area is ongoing.

There has long been a debate concerning the origin of the Antillean biota, and how much light biotic inclusions in amber might shed on it. Over the various ages were attributed to Dominican amber, but a turning point came with geological dating of the sediments in which the amber deposits were encased, providing a minimum age of Middle Miocene for origin and deposition (Iturralde-Vinent and MacPhee 1996; Iturralde-Vinent 2001 a, b). Although a number of recent papers endorse the idea that the mammalian fauna, at least, did not arrive in the West Indies until late in the Neogene, other contributions—mostly based on invertebrate taxa—suggest that at least some of the main islands were both subaerial and potentially colonizable in the late . One such proposal, the GAARlandia hypothesis (Iturralde-Vinent and MacPhee 1999), has received a fair amount of recent attention. The GAARlandia landspan was conceived as a subaerial peninsular connection between northeastern South America and Cuba/Hispaniola/Puerto Rico (then conjoined) which existed around 35- 32 My ago and subsequently foundered ca. 32 My ago (see also Iturralde- Vinent 2006; MacPhee and Iturralde-Vinent 2005). This brief land connection allowed colonization of the Greater Antilles by certain kinds of South American organisms. Others presumably reached the islands over time by overwater rafting and other dispersal mechanisms, thereby contributing to the present diversity of the island´s biota. Representatives of these taxa are not infrequently found in Dominican amber, including

8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene 7 reptiles (lizards), (feathers, nesting materials), and (insectivore, hair) in addition to a wide variety of invertebrates (chiefly arthropods). This suggests in turn the existence of a highly diverse—and possibly significantly ancient—biota, one that must be significantly older than the snapshot provided by amber inclusions. Yet the age and origin of Dominican Republic amber remains crucial to the paleobiogeographical debate, in part because amber inclusions permit calibration of molecular clocks and thus the timing of divergences between mainland and insular lineages. These issues will be presented and discussed during this keynote presentation.

The known palaeodiversity in from Myanmar has increased dramatically over the past few years. By the end of December 2018, 38 classes, 105 orders, 535 families, 881 genera and 1192 species had been recorded or described (including 8 classes, 67 orders, 488 families, 814 genera and 1117 species of arthropods).

Theodore D.A. Cockerell (1916) was the first to record inclusions, and by the end of 1920 had described 42 species of insects, and a . The first was recorded by Dixon (1922). In the 1990s palaeoentomologists reinvestigated the collection at the Natural History Museum (London) and Rasnitsyn (1996) mentioned the first , snail and reptile skin (figured by Ross, 1998). Further material started to become available and Grimaldi et al., (2002) recorded the first , worms, velvet worm, bird feather and . Further new records of invertebrates, , plants and fungi were published over the following years (e.g. Poinar & Poinar, 2004). In recent years, new mines have opened up to supply the Chinese market, and amazing vertebrate inclusions have appeared such as frogs (Xia et al., 2015), lizards (Daza et al., 2016), birds (Xing et al., 2016a) and a dinosaur (Xing et al., 2016b).

Currently there are 33 orders of hexapods and 13 orders of arachnids known, which is the highest for any amber. Remarkably this includes extinct orders. Three new extinct orders of insects were named- Alienoptera Bai et al., 2016, Aethiocarenodea Poinar & Brown, 2016, and Tarachoptera Mey et al., 2017; however, the first two were recently included in the by Vršanský et al., (2018). In addition, the extinct taxa and Lophioneurida were resurrected as orders by Huang et al., (2016) and Ulitzka (2018) respectively, and the extinct Uraraneida was recorded by Huang et al. (2018) based on Chimerarachne Wang et al., 2018.

The total number of species has risen exponentially. In 1999 there were only 45 species known; however by the end of 2004, the total had more than doubled to 120, and by the end of 2009 had more than doubled again

8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene 9 to 259 species. By the end of 2015, the total had reached 507, and by the end of 2018 had more than doubled again to an incredible 1192 species. 320 species were named in 2018, which is by far the highest number of species named from any amber in any one .

Box 7, 00014 Helsinki, Finland 6Faculty of Biological and Environmental Sciences, University of Helsinki, P.O. Box 65, 00014 Helsinki, Finland The reconstruction of amber forests challenged scientists during the last decades, as interpretations of numerous inclusions led to conflicting assumptions about the structure and types of these forests and prevailing climates. To gain a better understanding of amber source areas, we suggest that inclusions of plants, lichens and fungi need to be considered. Plants primarily supply the forest structure and are excellent indicators for environment and vegetation structure. Some are keystone species whose effect on forest structure is large, and disproportionately large relative to their abundance. Unfortunately, plants are rare as amber inclusions and only a few amber deposits bear noteworthy amounts of determinable botanical inclusions. Lichens and fungi are often indicative for certain forest types and climate; however, lichens are likewise considered extremely rare in amber. Fungal inclusions are common in amber from many deposits around the world, but usually only sterile mycelia are preserved, which hampers the taxonomic treatment of most fossils.

We suggest that despite their rarity, the value of such inclusions can be extremely high, especially when certain indicator or keystone taxa are identified. Using Baltic amber as a case study, we demonstrate that inclusions of plants, lichens and fungi can significantly support the reconstruction of amber forests. We evaluated the paleoecology of various seed plants and ferns based on data from comparable Paleogene fossils and assemblages, and evaluated the functional morphology of fossil lichens and microfungi. Our recent survey of Baltic amber also tremendously increased the total number of fossil lichens and microfungi that are highly specific to certain

12 8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene forest types and climatic conditions.

Our reconstruction of the ‘Baltic amber forest’ is based on 15 genera of four families of conifers, on six families of angiosperms (where diverse dwarf mistletoes were identified as keystone species) and on the evaluation of the functional morphology of approximately 60 fossils and distinct morphologies of various calicioid fungi and lichens.

Inclusions of seed plants point to near-coastal / lowland such as coastal swamps, back swamps and riparian forests, as well as mixed- mesophytic -angiosperm forests with meadows and open areas. Several independent lines of evidence suggest warm-temperate humid but relatively well-illuminated temperate forests in the source area of Baltic amber.

This approach using multiple yet totally independent lines of evidence could be applied to other major deposits such as Dominican and Burmese amber, and possibly even to those preserving fewer inclusions of seed plants and cryptogams.

Fossils from the mid-Cretaceous (c. 100 Ma) Myanmar (Burmese) amber include all extant orders of Arachnida, including the earliest representatives of , , and . The most abundant and diverse arachnid order is the Araneae, with 44 families, 91 genera, and 167 species recorded to date. The araneofauna is dominated by haplogynes and palpimanoids, whilst araneoids are rare, and members of the RTA absent. In addition to the extant orders, an enigmatic spider-like arachnid, Chimerarachne, was described last year. What this tells us about spider evolution will be discussed. The arachnofauna is otherwise typical of a habitat, which concurs with evidence from other Burmese amber biota.

An instance of insect damage on a leaf reflects millions of years of evolution. Today, plants and insects contribute to more than 70% of

the biodiversity on the Earth. Their interactions are crucial for the TALKS environmental structure of continental ecosystems. Nevertheless, until the late Twentieth Century there was no formal ichnotaxonomy system to designate traces of insect feeding on fossil leaves. Focusing studies on these plant-insect interactions in the fossil record is a very recent discipline; only ten years ago Labandeira et al. (2007) compiled all the known plant-insect interactions in the fossil record, but new ones can always be found. Precisely, during investigations in the Lagerstätte of Willershausen (3 Ma, Germany), a new insect feeding trace has been identified, named DT297. This damage looks like a long-bent concatenation of circular perforations less than 5mm in diameter. There is also another “version” of this damage, twice as large, probably due to a different larval stage of the insect. In addition to this new release, there is another specificity for DT297, because now, despite more than 10,000 fossil leaves which have been analyzed, the DT297 is exclusively found on one plant species: Parrotia persica C.A.Mey (Hamamelidaceae). Moreover, this damage (i.e. DT297) has also been found on the present leaves of P. persica, which is today endemic to the Hyrcanian Forest (northern Iran). It has already been hypothesized that the present Hyrcanian forest was the best analogue of the European paleoforests from the late Cenozoic. The presence of DT297 on both fossil and current P. persica significantly supports this hypothesis. In conclusion, this discovery also raises several new questions and perspectives about the potential of plant-insect interactions as a good indicator in (paleo)ecology. These herbivory traces could provide insight into POSTERS the biogeographical history of a plant species, its evolution, and the evolution of its environment. In future studies of fossil leaf collections, the identification of plant-insect interactions should become an integral part of the analyses.

8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene 101 Cretaceous Odonata from the Koonwarra lagerstätte, Victoria, Australia

The Lower Cretaceous Koonwarra Fossil Bed is one of the most important fossil sites in Australia, discovered in the 1960s by workers straightening a section of the South Gippsland Highway in southeastern

TALKS Victoria, Australia. This lagerstätte, renowned for both the diversity and preservation of its fossils, is mainly known for its fossil fish, but is also abundant in invertebrates, including a wide range of insects.

The fossil odonatans, like other invertebrate fossils from this site, were first described in detail in 1986 by Peter Jell and Peter Duncan. Since then, several authors have questioned the classification of many of these specimens, and discovered discrepancies in some of the original specimen descriptions. Further, paleontology has progressed significantly since the 1980s, with technological advances enabling fine details on the specimens to be more easily visualised, and higher quality photos to be obtained. For this project, I reviewed all the fossil Odonata currently known from Koonwarra, including a new specimen found in March 2018. The specimens were re-imaged, re-described and reclassified wherever possible. In total, fourteen odonatan naiads and the partial wing of Peraphlebia tetrastichia Jell & Duncan, 1986 were re-described. All naiads were removed from the species Peraphlebia tetrastichia and placed into open nomenclature, with three separate morphologies identified.Niwratia elongata Jell & Duncan, 1986 was re-described as an anisopteran naiad and grouped with another of the anisopteran naiads due to morphological similarities, with both specimens potentially placed into the family Libellulidae. The other specimens could not be assigned to families due to the unclear preservation of diagnostic features. Of the zygopteran naiads from Koonwarra, two were described individually as each displayed unique POSTERS features separating them from the other fossils, with the remaining seven zygopterans likely representing a single species. None of the zygopteran naiads could be associated with any specific family; however, the material was compared to families such as the Synlestidae, Coenagrionidae and Perilestidae. The partial wing of Peraphlebia tetrastichia was removed

102 8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene from the family Mesophlebiidae, and left in open nomenclature, due to the missing basal portion of the wing. Using modern odonatans as an analogue, the palaeoenvironmental conditions represented at the Koonwarra site were confirmed to have an aquatic nature, either a lake or river. The small nature of the odonatan specimens suggests that the Koonwarra site would have been closer to a than a polar climate and year-round frosts could not have been possible — this idea agrees well with some previous interpretations of this site.

Laboratory of Evolutionary Entomology and Museum of Amber Inclusions, Department of Invertebrate Zoology and Parasitology, Faculty of Biology, University of Gdańsk, 59, Wita Stwosza St., PL80-309 Gdańsk, Poland; e-mail: [email protected] Achilidae Stål, 1866 is a planthopper family that is not very large and speciose, but has complex taxonomic subdivisions. It groups over 160 genera (6.6% of the Fulgoromorpha) and about 550 species (3.8% TALKS of the Fulgoromorpha). These taxa include extant and a few extinct representatives, and are distributed worldwide, but are more speciose in Northern Hemisphere’s tropical and subtropical zones. All Achilidae are obligatory phytophagous, opophagous terrestrial insects; they mainly feed on host plants belonging to the following orders: Arecales, Asparagales, Asterales, Boraginales, Cornales, Cupressales, Ericales, Fabales, Fagales, Hamamelidales, Lamiales, Laurales, Malpighiales, , Myrtales, Pinales, , Rosales, Sapindales, Vitales. The oldest fossil is known from the Lower Cretaceous (), and the highest number of extinct taxa are known from Eocene Baltic amber. Recently, a number of Achilidae and relatives were identified among Burmese amber inclusions.

Taxonomic history of Achilidae is complex, dependent on opinions and definitions of the groups in which it has been placed and which are placed within the family. The first fossils which need to be placed in the family were described in 1856 by Germar and Berendt, but were given as representing the genus Cixius of the family Cixiidae. During the following 135 years, another fossil from Baltic amber was named (Cockerell 1910), and also one from sediments (Cockerell 1922), then one more Baltic amber inclusion was described by Usinger (1939). Those fossils were treated in a family revision by Fennah (1950). The 1990’s brought several discoveries and changes: the first fossil of the oldest Achilidae from the Aptian Crato Formation (Acixiites Hamilton, 1990);

POSTERS the extinct tribe Ptychoptilini from Baltic amber (Emeljanov 1990); and new opinions on content, subdivisions and definition of the family (Emeljanov 1991, 1992, Emeljanov & Flecher 1994). The 21st Century brought more fossils: some from the extinct tribe Waghildini (Szwedo 2006); plus more genera and species (Lefebvre et al. 2007, Emeljanov

104 8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene & Shcherbakov 2009). The content and concepts of the family also changed – the status and placement of Achilixiinae, Bebaiotinae and Ptychoptilini as part of Achilidae were challenged. Discoveries of fossils in mid-Cretaceous amber from Myanmar brought more questions and challenges. Several fossils which could be placed in recent tribal classification were found, but changed the view on times and sequence of separation of tribes. Other fossils cannot be placed in known tribes and could represent families related to Achilidae. Cenozoic fossil resins – the Oise, Baltic and Dominican ambers – brought new taxa and new challenges for revisionary and taxonomic studies. Achilidae belongs to one of the oldest lineages among Fulgoroidea, and the diversification and dispersion of the group, its relationships and evolutionary scenarios, TALKS all seem to be pieces of a circuitous puzzle that needs to be assembled.

Bankowa 9, 40-007 Katowice, Poland; e-mail: [email protected]*, [email protected]** Only two representatives of Centrocnemidinae from Baltic Amber have been described so far: Redubitus centrocnemarius Putshkov & Popov, 1993 and Redubinotus liedtkei Popov & Putshkov, 1998. The modern TALKS fauna of the subfamily contains only 4 genera and about 30 described species, distributed exclusively in South and . During our study, an inclusion of a new adult specimen of a centrocneminous bug, which could not be placed in any of the known genera, was discovered in Baltic Amber deposited in the Collection of Department of Zoology, University of Silesia (DZUS). Yuriella popovi gen. nov., sp. nov. is the second known individual of Centrocnemidinae from Baltic Amber in the imaginal stage. It can be easily distinguished from Redubinotus liedtkei Popov & Putshkov, 1998 by its different head shape (postocular part is very narrow, eyes are large and placed anteriorly), the morphological characters of pronotum (anterior pronotal lobe is distinctly narrower than posterior pronotal lobe; posterior pronotal lobe with regular margins, distinctly formed 4 pairs of large denticles, and three) and scutellum (three large denticles visble on antero- lateral angles and on the apex of scutellum; apical denticle oriented horizontally). There are also visible differences in wing venation as well as the presence of denticles on the hind femur. This new genus and species will be described in honour of our late colleague Professor Yuri Alexandrovich Popov. POSTERS

Since its beginnings, the Spanish amber project has had a multidisciplinary approach, addressing topics such as the geology of the deposits and their age, the geochemistry and taphonomy of the amber, and the paleobiological data provided by amber inclusions. As the Spanish amber deposits are protected by law and all the samples were obtained in paleontological excavations carried out by specialists, all the material is housed in museums and other public institutions, which has allowed a rigorous investigation of the material unearthed so far.

During the Cretaceous, the Iberian plate was isolated as a large island on the western margin of the Tethys and partly bathed by the Proto- Atlantic. Eastern Iberian amber deposits are associated with freshwater swamps, whereas those in the north developed in deltaic environments with a more or less marine influence. The initial dating of the amber outcrops providing bioinclusions as Aptian‒Albian was subsequently adjusted, based on pollen and regional geology, to upper Albian. At least two different families of conifers produced the resin that originated the Spanish amber: and an indeterminate conifer in the northwestern deposits (El Soplao); close to the genus Agathis in the northern deposits (Peñacerrada), and possibly POSTERS also Cheirolepidiaceae in the eastern deposits (San Just). A number of hexapod orders have been found: , Blattodea (including Isoptera), Coleoptera, Collembola, Diptera, Hemiptera, Hymenoptera, Lepidoptera, Mantodea, Mecoptera, Neuropterida, Orthoptera,

8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene 107 , Thysanoptera, and Trichoptera. In terms of abundance, dipterans and hymenopterans are predominant. Other arthropod groups have also been discovered, such as arachnids (Araneae, Acari, and Pseudoscorpiones), as well as crustaceans (Tanaidacea, and Isopoda). A significant collection of feathers has also been recovered. Recently, Spanish amber has provided remarkable data on plant-insect interactions, namely those representing the first known and oldest direct evidences of pollination relationships between gymnosperms and different insect groups, i.e., thrips, long-proboscid flies and beetles. Other noteworthy subjects of paleobiological research have been the study of edaphic and aquatic arthropods and the evolution of TALKS camouflage in neuropterans. Lastly, actuotaphonomic studies carried out in Mexico and Madagascar have shed light on how representative the arthropod associations trapped in resin are when compared to the ecosystem composition. Differences in resin production and trapping capacity between angiosperms (Hymenaea ssp.) and gymnosperms (Agathis spp.) is now a work in progress. POSTERS

Dysodile are finely laminated rocks rich in organic matter and in fossils. Despite cropping out in different localities across Lebanon and belonging to different lacustrine geological formations (Barremian TALKS and Albian), dysodiles have scarcely been mentioned in the literature, leaving their depositional environment widely unknown. We focus herein on the Lower Barremian dysodiles, found in the fluvio-deltaic sandy facies of the “Grès du Liban” unit which include as well the amber deposits in Lebanon and the Levantine area. The studied deposits correspond to small lakes of limited extension (of a few km2). Their presence near to volcanic altered rocks, or associated with volcanic ash, suggests a possible relation between the volcanism and their deposition and/or preservation. Within their layers, Dysodile outcrops hide a huge diversity of macrofossils (ichtyofauna, chelonians, gastropods, plant debris and insects) and microfossils (, spores and pollen grains) that will provide us with an insight on Lower Barremian paleodiversity. We present herein a preliminary reconstruction of the depositional environment based on the fossil assemblages, geochemical (Rock-Eval) and optical (palynofacies and thin sections) analyses. This study sheds light on the paleontological importance of the dysodile shales, which could be hiding a ‘missing link’ that will improve our understanding of the evolution of modern fauna. To date, 40 fossil insects have been found preserved in dysodiles, belonging to Ephemeroptera, Diptera and Hymenoptera. The dysodiles (together with the Lebanese amber outcrops occurring in the same geological unit) will significantly add to the diverse new cradle of fossil insects from the Lower Barremian. POSTERS

TALKS The Nabidae (sensu Schuh and Štys, 1991) is a relatively small family of cimicomorphan bugs, with 31 genera and 386 extant species (after Coscarón et al., 2015). There is very little data on the fossil Nabidae sensu stricto despite several doubtful assignations. The oldest relatively accurate Nabidae sensu stricto are Middle Eocene. Here we describe the first Mesozoic representative of this family from mid-Cretaceous Burmese amber. Using microtomography X, fluorescence microscopy as well as classical microscopy, we created a 3D reconstruction to analyze the anatomical and morphological structures of its genitalia. We discuss the evolution of traumatic sex (traumatic insemination) within this family and the other cimicomorphan lineages.

*State Key Laboratory of Palaeobiology and Stratigraphy, Center for Excellence in Life and Paleoenvironment, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing 210008, People’s Republic of China; email:[email protected] Insects belonging to order Psocoptera Shipley, 1904 (sensu traditional classification), commonly known as booklice and barklice, are particularly rare as inclusions in Dominican amber. To date, only three psocopterans, assigned to three different families have been TALKS described from this amber material: Belaphopsocus dominicus Grimaldi and Engel, 2006 (); Myopsocus arthuri Nel et al., 2006 () and (Loxopholia) dominicanus Hakim et al., 2018 ().

The approximate age of Dominican amber has been subject to controversies during the last half-century, with several ages being attributed by different researchers. The latest was Iturralde-Vinent (2001), who studied the geology and stratigraphy of the various amberiferous deposits in Greater Antilles and assigned a mid-Miocene age (circa 16 myr) to the Dominican amber. From the latter, we studied, described and illustrated the new species Echmepteryx (Loxopholia) dominicanus Hakim et al., 2018. This taxa, which was attributed to subfamily Lepidopsocinae Enderlein, 1903, is the only fossil record of the subfamily. It is characterized by a distinctive head coloration pattern, the presence of scales and setae on various body parts and 40 antennal segments. Lepidopsocids, rather well diversified in recent fauna, remain very scarce as fossils. This new record is the first lepidopsocid species discovered from Dominican amber, thus the second oldest known lepidopsocid (the oldest occurring in the Eocene amber of Oise, France). Moreover, we described the female of species Myopsocus arthuri Nel et al., 2006, initially based on a male individual from the same amber. We also gave the specific diagnosis (missing in the original description), and we added some extra characters to the specific description (such as

POSTERS the distinctive head and thorax coloration pattern or the presence of a pulvillus on the claws) and compared this extinct species to the recent taxa found in the American continent. M. arthuri constitutes the only known fossil record for the family Myopsocidae.

Silesian University, Department of Zoology, 40-007 Katowice, Bankowa 9, Poland; e-mail: *[email protected],**[email protected], piotr.wegierek@ us.edu.pl*** The modern species belonging to Psallopinae are usually characterized (with some exceptions) by 2-segmented tarsi, the claws with a subapical tooth, a single on the membrane, very big eyes occupying almost the entire head nearly overlapping the gula, and very low-set antennae. TALKS All recent species generally have small bodies (usually 2-3 mm). Psallopinae, today mostly inhabiting tropical and intertropical regions, lead a cryptic life and their chorology is poorly known. Most of them were collected in light traps.

Up until now, representatives of five genera of Psallopinae have been described from Baltic and Dominican amber: Isometopsallops Herczek & Popov, 1992; Epigonomiris Herczek & Popov 1998; Cylapopsallops Popov & Herczek 2006; Epigonopsallops Herczek & Popov, 2009 (Baltic amber); and Psallops Usinger 1946. Some described fossil species (e.g. Cylapopsallops kerzhneri Popov & Herczek 2006, Isometopsallops schuhi Herczek & Popov, 1992, Epigonomiris skalskii Herczek & Popov 1998) differ from the recent forms by having a bigger body size (ca. 5 mm) and 3-segmented tarsi. However, all of them have a subapical tooth on claws, and do not have ocelli. A mosaic of the remaining morphological characters suggests a close relationship between Psallopinae and . A maximal reduction of ocelli in some fossil Isometopinae may suggest that Psallopinae is a taxonomic unit within Isometopinae (Herczek & Popov, 1992). The discovery of fossil psallopine bugs in Late Eocene Baltic and Ukrainian amber, especially the oldest representative Isometopsallus prokopi Vernoux, Garrouste & Nel, 2010 from Lowermost Eocene French amber, as well as a representative in Lower- Middle Miocene Dominican amber, indicates that the appearance and spreading of this peculiar mirid group happened not later than during

V. Matsui*, U. Naumenko & O. Remezova

Department of Mineral Deposits Geology, Institute of Geological Sciences, National Academy of Sciences, Ukraine, [email protected] The territory of Ukraine covers the southeastern part of the Baltic- Dnieper amber province, the latter stretching from the shores of the Baltic Sea to the Black Sea and the Sea of Azov. This province is the main source and supplier of succinate (Baltic) amber to world markets. The source area of this fossil resin was formed by erosion of paleopeats and lignite layers of Late Eocene age. Subsequent accumulation of TALKS resins (proto-amber) took place in the marine Eocene-Oligocene basin, which connected the tropical Tethys with the North Atlantic Ocean. The amber-succinite placer that formed in this basin was subsequently partially eroded and re-deposited again by river waters, glaciers and other geological denudation agents. The well-preserved remnants of Eocene fauna and flora can be found in these amber specimens. Other varieties of fossil resins are common in the Ukrainian shield (retinites) and in the Carpathian region (rumanite, deliatinite, etc.).

At present, amber-succinite is intensively mined in the Pripyat amber- bearing basin (north-western and northern parts of the Ukrainian Shield), and episodically in the Dnieper basin (the middle and lower part). The predicted resources of amber/succinite in the Pripyat basin are ca. 100 thousand tons. Most of the deposits and amber occurrences are related to the shallow-marine coastal and delta facies of the Lower Oligocene and, to a lesser extent, to the Upper Oligocene and continental formations of the Neogene and Pleistocene.

Shallow location of productive horizons, forests, swamps, lack of roads, and remoteness from large settlements contributed to the development of illegal mining, which led to significant environmental degradation. The state enterprise for amber extraction and processing is “Ukrburshtin,” which, along with a private company “Sonyachne remeslo,” satisfy the demands of the Ukrainian market. POSTERS

TALKS During the past ten years, many new fossil resin outcrops of different ages have been found on nearly all continents, ranging in age from the Late Carboniferous to the . Our knowledge on fossil terrestrial arthropods has greatly increased, thanks to the study of the inclusions in some of these resins, especially for the Cretaceous of Europe and Asia. Nevertheless, terrestrial fossil arthropods are clearly lacking in some areas crucial for the understanding of the Mesozoic and Cenozoic paleobiogeography. It is especially the case for the Indonesia. Even if these islands are hot spot for extant biodiversity, nearly no fossil arthropod is described from there. Cenozoic amber from Borneo, Java, and Sumatra has been recently found and analyzed, probably produced by trees of the family Dipterocarpaceae (Naglik et al. 2018). Nevertheless, no arthropod inclusion has been recorded in these resins. One of the authors has recently acquired a series of 200 arthropod inclusions from a trader from a Miocene amber outcrop in the western portion of the Central Sumatra Basin. The amber is red and rather opaque, due to numerous small bubbles and impurities. The insects are also frequently deformed, probably because the amber was partly heated by volcanic activity that occurred in the area during the Miocene (Kosmoswska-Ceranowicz et al. 2017). Nevertheless, the fauna is rather diverse with representatives of Coleoptera, Hymenoptera, Isoptera, Diptera, Dermaptera (three nymphs), Hemiptera (one Cicadellidae and one ), Lepidoptera, Neuroptera (), Orthoptera (a cricket), Odonata (wing fragment of a Zygoptera), and Thysanoptera. The most frequent fossils POSTERS belong to one species of Curculionidae: Platypodinae. The Formicidae (Formicinae, Ponerinae and Myrmicinae, workers and alate adults) and the (alate adults) are the second and third families in term of abundance. They are more numerous than the Diptera, which is relatively strange, since flies are generally very frequent in fossil resins.

116 8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene Diptera are represented by Mycetophilidae, Bibionidae, Chironomidae, Limoniidae, , Phoridae, and few other . One Staphylinidae: Pselaphinae and one Carabidae: Scaritinae have also been identified. Six Arachnida have also been found. This entomofauna suggests a forest under a warm and humid climate, especially for the abundance of Platypodinae and termites living in wood. A specimen of an apterous aquatic bug suggests the presence of freshwater very close to the resin-producing trees. Future studies can provide precious information on the Miocene fauna of the area and its relationships with extant fauna.

Therefore, I will make the first identification and official report pseudoscorpions preserved in the Turonian New Jersey amber. TALKS The specimens of interest were provided by the American Museum of Natural History and a private donor, currently in KU holdings. The specimens have embedded for conservation and have been imaged and illustrated. Computed tomography is used to visualize the specimen free from debris and imperfections in the amber and highlight diagnostic characters. The identification of these specimens will be added to the New Jersey amber faunal assemblage and provide additional fossil context for Pseudoscorpiones in the Mesozoic era. Currently, there are only four pseudoscorpions identified from the Mesozoic era, but by the end of this study there will be six therefore improving our knowledge of pseudoscorpions (Dunlop et al., 2019; Harvey, 2013).

The isopod suborder Phreatoicidea has the earliest known fossils in the Isopoda. Extant phreatoicideans live in epigean or hypogean fresh waters of Australia, , South Africa, and India, indicating that their biogeographical distribution originated from ancient Gondwana. Fossil records of phreatoicidean isopods include two palaeophreatoicids, TALKS Hesslerella from the Carboniferous of the U.S. and Palaeophreatoicus from the of Russia, and two amphisopid species of the genus Protamphisopus from the of China and Australia. In Triassic-Jurassic paleogeography, today’s phreatoicidean-harboring regions were surrounding Antarctica, implying an overlooked presence of this isopod group in Antarctica. In the course of a joint United States and British Antarctic expedition 1971/1972, multiple specimens of phreatoicidean isopod fossils were collected from lacustrine deposits intercalated in the late Kirkpatrick basalt at Carapace Nunatak of southern Victoria Land, Antarctica. An additional specimen—collected during the German GANOVEX IX expedition during 2005/2006 from a similar sedimentary interbed within Kirkpatrick basalt at Gair Mesa, northern Victoria Land—may indicate a wider distribution of this Jurassic phreatoicid in Antarctica. Detailed morphological features of the phreatoicidean fossils from Antarctica are being assessed, which will be used for phylogenetic analysis. Preliminary observations show that the Jurassic phreatoicideans from Antarctica have head and pereiopod features readily distinct from those of the Triassic Protamphisopus. The Jurassic specimens from Antarctica may thus provide more information about the morphology of Mesozoic phreatoicideans, and possibly cast light on the obscure biogeographic evolution of the group.

1Department of Zoology, Faculty of Science, Charles University, Viničná 7, Prague 2, Czech Republic; 2Borissiak Paleontological Institute, Russian Academy of Sciences, Profsoyuznaya 123, Moscow, 117647 Russia; *email: [email protected] Megasecoptera is one of the orders of Palaeodictyopterida, which occurred during the Late Carboniferous and Permian. The group shares with other palaeodictyopterids specialized piercing and sucking TALKS mouthparts in the form of a rostrum, which allowed it to stab plant tissues and suck juices. Representatives of Palaeodictyopterida varied greatly in size, wing venation complexity, and even in number of wing pairs (Paleodictyoptera are known for additional winglets on the prothorax, in contrast to some members of Permothemistida with hindwings reduced).

Most of the Megasecoptera families designated through the first half of the 20th century were frequently based on isolated wings only. The first described families (e.g. Mischopteridae, Sphecopteridae) come from the Late Carboniferous (Gzhelian; 303.4–298.9 Ma) of Commentry in France; however many of these specimens are heavily compressed, and the body structures are not finely preserved. Later, some adult specimens attributed to Protohymenidae, as well as nymphs of Mischopteridae, were described from Late Carboniferous (Moscovian; 315.2–307.0 Ma) of Mazon Creek sideritic nodules in USA. Another exceptionally preserved entomofauna comes from the Late Carboniferous (Bashkirian; 318.1–314.6 Ma) of Xiaheyan in northern China, which includes a large series of specimens of Brodioptera sinensis (Brodiopteridae), revealing new morphology details. This species demonstrated male and female external copulatory organs and allowed us to study intraspecific variability of wing venation. Rich material of megasecopterans has also been documented from an Early Permian locality – Tshekarda in the Russian Federation. Presently it includes members of four families:

POSTERS Bardohymenidae, Protohymenidae, Scytohymenidae, and Vorkutiidae, commonly found with well-preserved body structures.

The family Bardohymenidae comprises several assigned genera, but only genus Sylvohymen provides details of body morphology apart from the

120 8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene wings. Our study revealed a new specimen of male Sylvohymen sibiricus Kukalová-Peck, 1972, supplementing the previous female specimen. The male genitalia of S. sibiricus are comparable to other megasecopterans, consisting of segmented gonopods (forceps) and paired penial lobes. Another significant character of some megasecopterans is an apical cell in the wing venation, which seems to be variable in shape across the family Bardohymenidae, but rather stable among other families (e.g. Protohymenidae, Scytohymenidae).

Enrique Peñalver*, Mónica M. Solórzano Kraemer, Xavier Delclòs, Joaquín Baixeras & Victor Sarto i Monteys

*Instituto Geológico y Minero de España (Museo Geominero), 46004 Valencia, Spain; email: [email protected] Records of Lepidoptera are rare in amber due to taphonomic factors (Solórzano Kraemer et al., 2018), and consist mostly of adult moths. In Mesozoic amber, only adult moths have been found. From Miocene TALKS Dominican amber, several extant moth families have been cited or figured, but to date only two specimens of the family Tortricidae have been studied in detail, with the description of two extinct genera (see review by Heikkilä et al., 2018). We report an inchworm male moth virtually complete (except for some portions of the antennae) and finely preserved in a clear piece of Dominican amber (wingspan ca. 30 mm as preserved). Fore and hindwings appear only partially overlapped, and all body characters are visible externally in dorsal and ventral views, including the valvae of the genitalia. The scale pattern on the wing membrane is preserved, whereas the wing color pattern is not. The intact preservation of the wings, except for minor damage in the posterodistal margin of the left hindwing, reveals that the moth became trapped in resin shortly after emerging, to be rapidly and entirely covered by subsequent resin flows. This new specimen belongs to the family Geometridae, most likely being an Ennominae which appears to be close to the genus . Grimaldi & Engel (2005) figured another adult specimen and a in Dominican amber; their moth, which also belongs to Ennominae, differs from our specimen in some wing venation features. Because of the poor fossil record of lepidopterans, the description of the available well-preserved specimens is of considerable interest. We report for the first time an inchworm moth which could help improve future estimations of the rate of molecular change using molecular clocks.

Phoretic behaviour – cases of organisms attaching onto other organisms for the implied purpose of dispersal – is among the least understood

TALKS categories of interspecific associations. Consequently, instances of phoresy are often described as associations between small organisms and mobile larger ones that show no clear benefit other than transport. This holds especially true when trying to interpret the fossil record. Apart from a few Paleozoic reports, fossil springtails (Hexapoda, , Collembola) are primarily reported from Cretaceous and Cenozoic amber deposits, in which they have occasionally been documented as attached to other invertebrates. These fossil associations correspond to three cases of Symphypleona attached by the antennae to different parts of larger arthropods’ bodies (e.g. legs; Poinar 2010, Penney 2012, Grünemaier 2016). Remarkably, such instances of putatively phoretic behaviour have no known modern counterpart, which is very rare for repeated fossil behaviours.

Here, we document a new case of collembolan phoresy preserved in Dominican amber. A single amber specimen reveals associations with both termites and ants, displaying not just a few, but a striking 26 individuals attached to or in close proximity with social insects. This new Symphypleona species exhibits attachments on elements of host anatomy that have not been previously reported, as well as a specific antennal anatomy that includes rarely preserved fossil organs reflecting specific courtship behaviours. By (1) comparing the relative position of Collembola and potential hosts, (2) documenting modes of attachment, and (3) observing ratios in host/springtail

POSTERS antennal anatomies, we infer a likely attachment strategy for dispersal. In addition, by pointing out (1) hidden evidence of modern springtails associated with other invertebrates, such as ants and termites, (2) new cases of fossil syninclusions of Symphypleona and termites, and (3) the drastic increase of eusocial insects’ abundance in Cenozoic deposits (ants and termites together comprise up to a third of the total insect

124 8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene biomass in Miocene amber), we suggest that this behaviour, which is probably still performed by extant lineages, may be a reflection of co- evolution between Symphypleona and social insects over time.

8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene 125 Palynological studies of the Upper Triassic amber bearing levels of the Dolomites: Indications for conifer evolution

Guido Roghi*, Evelyn Kustatscher, Leyla Seyfullah & Alexander Schmidt

*Institute of Geoscience and Earth Resource, CNR, Padova, Italy. email: [email protected] The famous Upper Triassic amber of the Southern Alps comes from the Heiligkreuz Formation in the eastern Dolomites and the Rio del Lago Formation in the Julian Alps (e.g., Seyfullah et al., 2018). It was TALKS collected in levels also yielding dispersed cuticles/leaves, plant remains and wood fragments. This fossil resin became famous for its amazing inclusions preserved inside the single (small) amber droplets, permitting us to discover a microworld normally not preserved in the fossil record (Schmidt et al., 2006). In addition, the amber-bearing levels of the Dolomites (northern Italy) represent the only known source of early Mesozoic amber-preserved arthropods (Schmidt et al., 2012, Sidorchuk et al, 2015).

Through an integrated study of palynomorphs and macroremains, the fossil assemblage can be also used as a base for considerations on the evolutionary history of modern conifer families. At least three different conifer shoot types have been identified in the flora, attributed respectively to different conifer groups, i.e. Voltziales, Cheirolepidiaceae and ?Majonicaceae (Roghi et al., 2006). The palynological analyses of the amber-bearing horizons have yielded a wide range of pollen grains assignable to conifers such as bisaccates (Triadispora group, Voltziales) and taeniate bisaccates (Majonicaceae?), monosaccates (Voltziales, Majonicaceae?) and Circumpolles (Cheirolepidiaceae), indicating that several conifer families coexisted during this period in the Dolomites. However, these conifer groups are not all specific to the sediments they were found in, since Majonicaceae is a Permian conifer family, and the Cheirolepidiaceae is typical for the Jurassic and Cretaceous. The Late Triassic conifers in Europe generally belong solely to the Voltziales.

POSTERS Morever, the taeniate bisaccate pollen grains are not rare elements, but are in fact represented by several genera (Lueckisporites, Lunatisporites, Infernopollenites) that are abundant in the palynoflora. These findings re- open the discussion on the origination, disappearances and radiations of several major conifer groups in the Triassic.

While adults are rather frequent, the nymphal stages of Palaeodictyopterida are scarcely found in Paleozoic deposits. They are commonly preserved only as isolated wing pads or as complete body exuviae. The nymphal wing pads of Palaeodictyoptera were medially articulated; however, it is still unknown whether they were at least partially movable. In contrast, the nymphal wing pads of extant species of and Neoptera are fully fused with the notum, and are immovable. The original function of palaeodictyopteran wing pads also remains unclear. In the past, a wide range of hypotheses for their function have been proposed, for instance for thermoregulation, gliding or even active flight. Moreover, some members of Palaeodictyoptera and Geroptera (Odonatoptera) possessed developed prothoracic lobes, so-called winglets.

We reexamined very rare material in detail, consisting of a series of palaeodictyopteran nymphal wing pads attributed to Tchirkovaea guttata (Tchirkovaeidae) from the Early Permian of Tschekarda in Russia. This material allowed us to study developing wing pads during various nymphal stages, along with other body structures. We compared our results with the growth of developing wings in selected groups of extant insects. Such comparisons can provide more information on wing growth during postembryonic development in one of the oldest groups of Pterygota.

The ability of resin to encapsulate small portions of the paleoecosystem in a relatively fast and quasi-unaltered way, and to preserve them for millions of years, gives amber paleobiological significance, and explains why amber inclusions are especially valuable for studying how TALKS organisms interacted in the past. Here we present extraordinary amber assemblages of inclusions that provide evidence of some ethologies associated with social or pre-social aggregations in springtails (Hexapoda: Collembola). Such behaviors, while critical for the success of species, are frequently impossible to determine for fossil species. The earliest evidence of aggregating behavior in Collembola was documented in an entomobryomorhan species, Proisotoma communis, preserved in Late Albian Peñacerrada I (Spain) amber (Sánchez-García et al., 2018). The discovery of fossil evidence for swarming in P. communis demonstrated considerable ethological stasis of some behaviors that are common in extant Collembola. Now, direct evidence of aggregating behavior in Collembola is provided by newly found associations of entomobryomorphan springtails preserved in fossil and Recent resins, produced by both gymnosperms and angiosperms, from different locations and ages: in Cenomanian (99 Ma) Burmese amber; and in Miocene (20 Ma) Dominican amber; as well as in Recent Hymenaea verrucosa resin from Madagascar. This considerably expands the fossil evidence of this behavior. It is remarkable that all of the springtail assemblages are found in litter amber/resin pieces, and also preserve different elements and organisms typical of the forest floor. The diverse samples composed of litter-inhabiting fauna were entombed by resin flows directly onto the ground from different parts of the source trees. The superb preservation of the samples has allowed us to study not only their content, but their taphonomical characteristics. These specimens POSTERS constitute surprising examples of swarming on the forest floors and shed new light on the edaphic habitats of these deep-time forests.

Microtomography has allowed us to observe in three dimensions the morphology of a new species of Eocene cockroach preserved in a cracked amber fragment from the Oise lowermost Eocene amber (France). The current classification of the Blattodea, even at a familial rank, is primarily based on genitalia characters, but these structures are generally not preserved in fossils, rendering any assumptions on their affinities very doubtful. In our case, the scanned specimen, a male, has its genitalia partially devaginated. This allows very precise observation and, consequently, an assignment to the modern family Ectobiidae, more precisely to the subfamily Blattellinae, with a high level of confidence. To our knowledge, this is the first reliable fossil of this subfamily. It is of major interest in understanding the evolution of modern roaches, as well as studying the phylogeny and dating the Blattellinae. Moreover, this taxonomic identification highlights a case of regarding the exceptionally elongated morphology of this fossil. POSTERS

Laboratory of Evolutionary Entomology and Museum of Amber Inclusions, Department of Invertebrate Zoology and Parasitology, Faculty of Biology, University of Gdańsk, 59, Wita Stwosza St., PL80-309 Gdańsk, Poland; e-mail: [email protected] The Museum of Amber Inclusions (MAIUG) was established in

1998 by the University of Gdańsk Senate. The founder of the Museum, TALKS Professor Ryszard Szadziewski, was then the head of the Department of Invertebrate Zoology. The MAIUG is now an integral part of the Laboratory of Evolutionary Entomology and the Department of Invertebrate Zoology and Parasitology, Faculty of Biology, University of Gdańsk, Poland. The university’s collection of amber inclusions is extensive, preserving numerous amber pieces, and particularly amber samples with biological inclusions for taxonomic research. In addition, it is a fundamental tool for understanding the palaeobiodiversity, palaeobiology and palaeoecology of the ancient amber forest.

The Museum was an outgrowth of the collaboration between scientists and the amber-workers of Gdańsk, who were focused on a return to the pre-World War II tradition of collection and research on the natural history of amber. The museum’s collections and activities began humbly with an initial number of 63 amber pieces with inclusions, 50 kg of raw Baltic amber, and a small dark room with a simple polishing machine and steel cabinet housed in the former Department of Invertebrate Zoology in Gdynia in 1998. The collection was erected for scientific purposes, but with a growing number of specimens and growing interest in amber inclusions, the educational and exhibition aspects of the museum were developed, as well as meetings and courses devoted to amber and its inclusions. In 2013, the Department and Museum moved to a new building of the Faculty of Biology. In this building,

the Amber Laboratory was established, with new equipment for POSTERS preparation of amber samples and for documenting inclusions, which has significantly facilitated new research. The Museum now contains a 150m2 exhibition area with a life-size diorama of the Baltic amber forest, and a diverse selection of Baltic amber inclusions on display. The MAI UG collection presently includes nearly 6000 amber pieces with

8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene 133 over 15000 described zooinclusions, including over 60 Type specimens. Eocene Baltic amber is the main component of the collection. However, other fossil resins with and without bioinclusions are also housed there. A fossil database of the bioinclusions is available, with numerous data recorded concerning each amber piece itself, organisms entombed within (inclusions and syninclusions), its provenance, collectors and investigators, as well as treatment. All these data are unique and provide a reliable base for understanding the palaeobiodiversity, palaeobiology and palaeoecology of the ancient amber forest, and also enable researchers to carry out taxonomic and taphonomic studies concerning amber and its inclusions.

They exhibit a setose arolium and short first tarsomere, which are evaluated here as potential apomorphic characters of Systellognatha. Tarsal euplantulae and numerous crossveins in the costal field are plesiomorphies shared with remaining Systellognatha. The plesiomorphic proximal origin of RP excludes the position of the new family in the crown group Systellognatha, and RA reaching the wing apex might be an autapomorphic character of the new family. Also discussed is the first Cretaceous larval specimen of : , along with another four new species that are placed within the recently described Acroneuriinae genus Largusoperla Chen et al., 2018.

8th International Conference on Fossil Insects, Arthropods & Amber | Edited by Paul C. Nascimbene 135 Unique characteristics of amber ((Hemiptera, Aphidomor- pha) fauna from the mid-Cretaceous Burmese amber of northern Myanmar

Piotr Wegierek & Aleksander Herczek

Department of Zoology, University of Silesia in Katowice, Bankowa 9, 40-007 Katowice, Poland; email: [email protected] The Cretaceous and particularly mid-Late Cretaceous constitute a crucial period in aphid phylogeny. It was during this period that most recent groups of insects originated. Only several Cretaceous TALKS have been described based on rock impressions. Our understanding of Late Cretaceous fauna relies primarily on genera and species found as amber inclusions.

Aphids are reported from several Mesozoic fossil resins, including Lebanese, Spanish and New Jersey ambers, which all originated in a warm climatic zone. Although each of these amber sites has yielded thousands of inclusions, aphids in these sites have been scarce (a total of 5 species described from 5 inclusions). In contrast, aphids are quite common in mid-Cretaceous Burmese amber.

The majority of described aphid taxa from this amber belong to family Burmitaphididae; 3 species represent Isolitaphidae; whereas Parvaverrucosidae and Szelegiewicziidae contain one species each. The Burmese amber aphid fauna is highly endemic: representatives of Isolitaphidae, and Parvaverrucosidae have only been reported from that location. Interestingly, the Burmitaphididae family, which is the richest overall in fossil species (6) and specimens (16), contains only a single specimen from Spanish amber: Alavesiaphis margaritae Peñalver and Wegierek, 2008. The uniqueness of fauna from Burmese amber is also manifest by the fact that the frequency of males present as inclusions in this amber is very high; this is not typical of aphids elsewhere.

Accordingly, the question arises: what abiotic and biotic conditions

POSTERS were responsible for forming such a unique aphid fauna from Burmese amber?

10, D-38678 Clausthal-Zellerfeld, [email protected]; elke.groening@ TALKS tu-clausthal.de The large quarry within the Piesberg N Osnabrück, Lower Saxony, Germany, is mainly known for its rich and exceptionally preserved fossil flora. But it is also a very important Late Carboniferous (Pennsylvanian: Westphalian C/D) locality for fossil insects. More than 200 specimens, mainly preserved as isolated wings, have been collected during the last three decades. Most of them were found by two collectors over the last 10 years. They are still housed in private collections and are not yet described. They altogether comprise more than 20 new individuals of Odonatoptera: . Their description is in preparation by the present authors. Thus the Piesberg is one of the most important Fossil-Lagerstätten of Late Carboniferous Odonatoptera in Europe. Till now only Erasipterella piesbergensis BRAUCKMANN, 1983 and Piesbergtupus hielscheri ZESSIN, 2006 had been named. One of the new specimens is a nearly complete animal which is documented herewith for the first time. Some additional photographs show how the Piesberg quarry developed during the last few years.
