(Protohymenidae) displays features in venation similar to taxa known from early and late Permian from the USA and Russia. A new palaeodictyopteran wing attributable to Carrizopteryx cf. arroyo (Calvertiellidae) provides data on fore wing venation previously unknown. Thus, all these new discoveries show close relationship between late Pennsylvanian and early Permian entomofaunas. Keywords Ephemeropterida; Diaphanopterodea; Megasecoptera; Palaeodictyoptera; gen. et sp. nov; early Asselian; wing venation Introduction The fossil record of insects from continental deposits near the Carboniferous-Permian boundary is important for correlating insect evolution with changes in climate and in plant ecosystems. One of the most prolific localities is Carrizo Arroyo situated in central New Mexico, USA, with an approximately 100-m-thick section of the latest Pennsylvanian (late Gzelian) to Early Permian (early Asselian or equivalent Wolfcam- pian) fauna and flora (Lucas et al. 2016, Schneider et al. 2016). Other well-known © Koninklijke Brill NV, Leiden, 2017 DOI 10.1163/1876312X-48022160 Downloaded from Brill.com09/27/2021 05:05:25AM via free access <UN> <UN> 494 J. Prokop and J. Kukalová-Peck / Insect Systematics & Evolution 48 (2017) 493–511 insect localities slightly older than Carrizo Arroyo come from Europe as Wettin in Germany and Commentry in France (both Gzhelian) or somewhat younger as Obora in the Czech Republic (Sakmarian–Artinskian). Insects occur in two freshwater lay- ers inter-bedded by marine deposits of the Bursum Formation (Red Tanks Member) of early Asselian age. The entomofauna was first collected almost forty years ago by Kukalová-Peck & Peck (1976) and later extended by Lucas and Krainer (2004), Ras- nitsyn et al. (2004) and by Schneider et al. (2004). However, a number of specimens housed in private and institutional collections are still awaiting description. The fol- lowing insect groups, almost entirely represented by wings, were described in pre- ceding studies: Archaeognatha, Odonatoptera, Diaphanopterodea, Palaeodictyoptera, Megasecoptera, Orthoptera, Caloneurodea, “Grylloblattida”, Blattodea, “Hypoper- lida”, Psocodea, Hemiptera, “Miomoptera”, Mecopterida (Kukalová-Peck and Peck 1976; Shear et al. 1992; Rowland 1997; Rasnitsyn et al. 2004; Schneider et al. 2004; Nel et al. 2012). The material described here was collected by the second author (JKP) in 1976 with the assistance of legendary Czech collectors Mr. Karel Havlata and Mrs. Anna Havlatová (both sampled for decades together with JKP famous Early Permian Moravian localities in the Boskovice furrow). In this contribution, we describe new taxa of Hydropalaeoptera (Ephemeropterida: Syntonopteroidea) and of †Rostropalae- optera (Diaphanopterodea, Megasecoptera, Palaeodictyoptera). Material and methods The fossil specimens preserved in fine grained greenish grey sediment were observed under a stereomicroscope WILD M5A in a dry state. The venation pattern line draw- ings were made directly through a stereomicroscope with a coupled camera lucida. Photographs were taken by digital camera Canon D550 with lenses MP-E 65 mm and EF 50 mm. Original photographs were processed using the image-editing software Adobe Photoshop CS and for some images were used stacking software Helicon Focus Pro 6.2.2. Type material is housed in the Kukalová-Peck collection, awaiting deposition in the Canadian Museum of Nature, Ottawa, ON, Canada. Specimen No. 2927/20639 is deposited in the collection of The Natural History Museum in San Diego, CA, USA. We follow the wing venation nomenclature in general of Kukalová-Peck (1991). The venational symbols used here specified as follows: symbols in capitals denote the longi- tudinal veins (ScA/ScP, subcostal anterior/posterior; RA/RP, radial anterior/posterior; MA/MP, medial anterior/posterior; CuA/CuP, cubital anterior/posterior; AA/AP, anal anterior/posterior); ‘IN-’, concave vein between AA1+2 and AA3+4. Other symbols used for morphological structures: ng, nygma. Systematics and higher divisions follow the concept of Ephemeropterida: Syntonopteroidea sensu Prokop et al. (2010), Pal- aeodictyopteroida sensu Bechly (1996, 2014), Riek (1976), and Sinitshenkova (2002).

  • THE ORIGIN and EVOLUTION of HYMENOPTEROUS INSECTS [P
    THE ORIGIN AND EVOLUTION OF HYMENOPTEROUS INSECTS [p. 24] Chapter 3 EVOLUTION OF THE INFRACLASS SCARABAEONES A. P. Rasnitzyn* Dragonflies [order Odonata] and mayflies [order Ephemeroptera], which have retained a primitive thorax structure (absence of a cryptosternum) but are specialized in other respects, occupy the most isolated position in the infraclass. They are similar to each other in a number of characters, but the nature of the latter does not allow drawing a conclusion about any close relationship of the two orders. Indeed, the primitiveness of the structure of the thorax common to both of them, like any symplesiomorphy, is not evidence of a common origin. The adaptations of the larvae of mayflies and dragonflies to an aquatic way of life are different, and they show, rather, an independent transition to development in water. The loss of the ability to fold the wings as well is connected with different processes in them: in mayflies, with the ephemerality of the imago, the function of which is essentially limited to nuptial flight and oviposition; and in dragonflies, with the metamorphosis of the adult insect to an active aerial predator. It is highly probable that mayflies and dragonflies are independent evolutionary branches. The belonging of dragonflies and mayflies to a common trunk of Scarabaeones, that is, the isolation of them from Protoptera as part of a single trunk with the remaining members of the infraclass (except Protoptera), is confirmed by the metamorphosis of the style of the ninth segment in mayfly males into part of the copulatory organ [endophallus], and in dragonfly females into a sheath of the ovipositor.

  • Evolution of the Insects David Grimaldi and Michael S
    Cambridge University Press 0521821495 - Evolution of the Insects David Grimaldi and Michael S. Engel Frontmatter More information EVOLUTION OF THE INSECTS Insects are the most diverse group of organisms to appear in the 3-billion-year history of life on Earth, and the most ecologically dominant animals on land. This book chronicles, for the first time, the complete evolutionary history of insects: their living diversity, relationships, and 400 million years of fossils. Whereas other volumes have focused on either living species or fossils, this is the first comprehensive synthesis of all aspects of insect evolution. Current estimates of phylogeny are used to interpret the 400-million-year fossil record of insects, their extinctions, and radiations. Introductory sections include the living species, diversity of insects, methods of reconstructing evolutionary relationships, basic insect structure, and the diverse modes of insect fossilization and major fossil deposits. Major sections cover the relationships and evolution of each order of hexapod. The book also chronicles major episodes in the evolutionary history of insects: their modest beginnings in the Devonian, the origin of wings hundreds of millions of years before pterosaurs and birds, the impact that mass extinctions and the explosive radiation of angiosperms had on insects, and how insects evolved the most complex societies in nature. Evolution of the Insects is beautifully illustrated with more than 900 photo- and electron micrographs, drawings, diagrams, and field photographs, many in full color and virtually all original. The book will appeal to anyone engaged with insect diversity: professional ento- mologists and students, insect and fossil collectors, and naturalists. David Grimaldi has traveled in 40 countries on 6 continents collecting and studying recent species of insects and conducting fossil excavations.

  • Carboniferous Protodonatoid Dragonfly Nymphs and the Synapo- Morphies of Odonatoptera and Ephemeroptera (Insecta: Palaeoptera)
    Palaeodiversity 2: 169–198; Stuttgart, 30.12.2009. 169 Carboniferous protodonatoid dragonfly nymphs and the synapo- morphies of Odonatoptera and Ephemeroptera (Insecta: Palaeoptera) JARMILA KUKALOVÁ-PECK Abstract Three extremely rare fossil protodonatoid dragonfly nymphs are described from the middle Pennsylvanian (Moscovian) of Mazon Creek, Illinois: Dragonympha srokai n. gen., n. sp. (Meganisoptera), a large, nearly com- plete young nymph with an extended labial mask and uplifted wing pads; Alanympha richardsoni n. gen., n. sp. (Meganisoptera), a nymphal forewing with two articular plates attached to it; and Carbonympha herdinai n. gen., n. sp. (Eomeganisoptera), a detached nymphal forewing. Plesiomorphic states in Dragonympha n. gen. indicate ho- mologies unresolved in modern Odonata. The segmented head bears 3rd tergum ventrally invaginated. The extended labial mask still shows limb segments. The prothorax bears a pair of winglets. The short wing pads are fully articu- lated, twisted, uplifted and streamlined with body. The mesothoracic anepisternum is placed between acrotergite and prescutum. The abdominal leglets form long, segmented, serial gill filaments. In the ontogenesis of modern dragonflies, the wing and articulation disc occurs just above subcoxal pleuron and far from tergum. Wing sclerites are arranged in eight rows protecting eight blood pathways running towards eight wing veins. The sistergroup of Odonatoptera has not yet been convincingly resolved with computer cladistic approaches. Reasons are examined and discussed. More accurate, evolution-based character evaluations are shown with examples. The role of a correct model of the pan-arthropod limb and the origin of insect wings is discussed. Groundplan characters in dragonflies and mayflies are compared in their Paleozoic and modern states, their obscurity is clarified and complex synapo- morphies are proposed.

The Dermaptera are a small order of insects, marked by reduced forewings, hindwings with a unique and complicated folding pattern, and by pincer-like cerci. Hindwing characters of 25 extant dermapteran species are documented. The highly derived hindwing venation and articulation is accurately homologized with the other pterygote orders for the first time. The hindwing base of Dermaptera contains phylogenetically informative characters. They are compared with their homologues in fossil dermapteran ancestors, and in Plecoptera, Orthoptera (Caelifera), Dictyoptera (Mantodea, Blattodea, Isoptera), Fulgoromorpha and Megaloptera. A fully homologized character matrix of the pterygote wing complex is offered for the first time. The wing venation of the Coleo- ptera is re-interpreted and slightly modified . The all-pterygote character analysis suggests the following relationships: Pterygota: Palaeoptera + Neoptera; Neoptera: [Pleconeoptera + Orthoneoptera] +

However, the fossil record o pteralia in extinct orders is extremely scanty. This paper is concerned with the wing bases of certain Paleozoic Paleoptera, namely, Palaeodictyop- tera, Megasecoptera and Diaphanopterodea rom the Upper Carboni- ferous (Namurian) of Czechoslovakia, the Upper Carboniferous (Stephanian) of France, and the Lower Permian of Czechoslovakia and Kansas. Independently of the Neoptera, the Diaphanopterodea acquired the ability to flex the wings backwards over the abdomen. In this respect, the order is of special interest, and an attempt is made here to compare the pteralia o the Diaphanopterodea with those of extant Ephemeroptera. Our present knowledge of the wing base in Paleozoic Paleoptera is restricted to the axillary plate o several palaeodictyopteran adults (Kukalova, 96o, 969-7o), and palaeodictyopteran nymphs (Woot- ton, 972; Sharov, 97I) [See figures , 2 and 4]. Recently, the wing base has been described in the Diaphanopterodea, Family E1- moidae (Kukalova-Peck, 974) (/]g. 8). In the present paper, the axillary plates in Martynoviidae and Asthenohymenidae o the Order Diaphanopterodea are included, and for the first time the axillary sclerites in Megasecoptera are described. The interpretation and terminology of the pteralia in extinct Pale- optera are necessarily dependent upon the detailed functional mor- phology of extant Ephemeroptera and Odonata. At the same time, the wing base structures found in extinct orders provide an evolu- tionary view and might be helpful in unraveling the enigmatic archi- *This research has been aided in part by a Publication Grant from Carleton University and in part by a National Science Foundation Grant, GB 39720, F.

  • The Occurrence and Diversity of Coal Measure Insects
    Journal of the Geological Sociev, London, Vol. 144, 1987, pp. 5W-511, 3 figs. Printed in Northern Ireland The occurrence and diversity of Coal Measure insects E. A. JARZEMBOWSKI Booth Museum of Natural Hktory, Dyke Road, Brighton BN1 5AA, UK Abslrnd Insects are generally considered to be rare in the Upper Carboniferous Coal Measures. However, recent work in the Westphalian D of SW England suggests that many have been overlooked in the past. This is because wings, which are the most characteristic insect fossils, may be mistaken for detached ‘fern’ pinnules, which are much more common. The resemblance may be functional convergence rather than leaf-mimicry. The earliest members of the class Insecta in the strict sense occur in the Upper Carboniferous. Eleven major divisions or orders are represented in the Coal Measures of which only four are still living. Primitively wingless insects (Archaeognatha) are present, relatives of familiar living insects such as the silverfish. There are numerous winged insects, some ofwhich could fold their wings (Neoptera) and others which could not (Palaeoptera). Palaeopterous insects were more diverse than today. They include three extinct orders (Palaeodictyoptera, Megasecoptera, Diaphanopterodea) which were probably plant suckers like present clay bugs. Other extinct palaeopterous insects (order Protodonata) were probably aerial predators like modem dragonflies, and included some of the largest insects of all time (‘giant dragonflies’). By far the most common neopterous insects were cockroaches (Blattodea) which outnumber all other insects in theUpper Carboniferous. This abundance is perhaps less surprising when one considers the general picture of the coal forests as warm, humid, and rich in organic matter.
