Nests of ants in the Ponerinae subfamily harbor a rich diversity of invertebrate commensals that maintain a range of interactions which are still poorly known in the Neotropical Region. This study aims to investigate the diversity of these invertebrates in nests of several species of the genus Neoponera and search for possible differences in their commensal fauna composition in two distinct habitats: the understory and the ground level of cocoa tree plantations. -
The Mitochondrial Genomes of Palaeopteran Insects and Insights
www.nature.com/scientificreports OPEN The mitochondrial genomes of palaeopteran insects and insights into the early insect relationships Nan Song1*, Xinxin Li1, Xinming Yin1, Xinghao Li1, Jian Yin2 & Pengliang Pan2 Phylogenetic relationships of basal insects remain a matter of discussion. In particular, the relationships among Ephemeroptera, Odonata and Neoptera are the focus of debate. In this study, we used a next-generation sequencing approach to reconstruct new mitochondrial genomes (mitogenomes) from 18 species of basal insects, including six representatives of Ephemeroptera and 11 of Odonata, plus one species belonging to Zygentoma. We then compared the structures of the newly sequenced mitogenomes. A tRNA gene cluster of IMQM was found in three ephemeropteran species, which may serve as a potential synapomorphy for the family Heptageniidae. Combined with published insect mitogenome sequences, we constructed a data matrix with all 37 mitochondrial genes of 85 taxa, which had a sampling concentrating on the palaeopteran lineages. Phylogenetic analyses were performed based on various data coding schemes, using maximum likelihood and Bayesian inferences under diferent models of sequence evolution. Our results generally recovered Zygentoma as a monophyletic group, which formed a sister group to Pterygota. This confrmed the relatively primitive position of Zygentoma to Ephemeroptera, Odonata and Neoptera. Analyses using site-heterogeneous CAT-GTR model strongly supported the Palaeoptera clade, with the monophyletic Ephemeroptera being sister to the monophyletic Odonata. In addition, a sister group relationship between Palaeoptera and Neoptera was supported by the current mitogenomic data. Te acquisition of wings and of ability of fight contribute to the success of insects in the planet. -
First Evidence of Specialized Feeding on Ectomycorrhizal
Bluhm et al. BMC Ecol (2019) 19:10 https://doi.org/10.1186/s12898-019-0227-y BMC Ecology RESEARCH ARTICLE Open Access Protura are unique: frst evidence of specialized feeding on ectomycorrhizal fungi in soil invertebrates Sarah L. Bluhm1*, Anton M. Potapov1,2, Julia Shrubovych3,4,5, Silke Ammerschubert6, Andrea Polle6 and Stefan Scheu1,7 Abstract Background: Ectomycorrhizal fungi (ECM) play a central role in nutrient cycling in boreal and temperate forests, but their role in the soil food web remains little understood. One of the groups assumed to live as specialised mycorrhizal feeders are Protura, but experimental and feld evidence is lacking. We used a combination of three methods to test if Protura are specialized mycorrhizal feeders and compared their trophic niche with other soil invertebrates. Using pulse labelling of young beech and ash seedlings we analysed the incorporation of 13C and 15N into Acerentomon gallicum. In addition, individuals of Protura from temperate forests were collected for the analysis of neutral lipid fatty acids and natural variations in stable isotope ratios. Results: Pulse labelling showed rapid incorporation of root-derived 13C, but no incorporation of root-derived 15N into A. gallicum. The transfer of 13C from lateral roots to ectomycorrhizal root tips was high, while it was low for 15N. Neutral lipid fatty acid (NLFA) analysis showed high amounts of bacterial marker (16:1ω7) and plant marker (16:0 and 18:1ω9) fatty acids but not of the fungal membrane lipid 18:2ω6,9 in A. gallicum. Natural variations in stable isotope ratios in Protura from a number of temperate forests were distinct from those of the great majority of other soil invertebrates, but remarkably similar to those of sporocarps of ECM fungi. -
Biochemical Divergence Between Cavernicolous and Marine
The position of crustaceans within Arthropoda - Evidence from nine molecular loci and morphology GONZALO GIRIBET', STEFAN RICHTER2, GREGORY D. EDGECOMBE3 & WARD C. WHEELER4 Department of Organismic and Evolutionary- Biology, Museum of Comparative Zoology; Harvard University, Cambridge, Massachusetts, U.S.A. ' Friedrich-Schiller-UniversitdtJena, Instituifiir Spezielte Zoologie und Evolutionsbiologie, Jena, Germany 3Australian Museum, Sydney, NSW, Australia Division of Invertebrate Zoology, American Museum of Natural History, New York, U.S.A. ABSTRACT The monophyly of Crustacea, relationships of crustaceans to other arthropods, and internal phylogeny of Crustacea are appraised via parsimony analysis in a total evidence frame work. Data include sequences from three nuclear ribosomal genes, four nuclear coding genes, and two mitochondrial genes, together with 352 characters from external morphol ogy, internal anatomy, development, and mitochondrial gene order. Subjecting the com bined data set to 20 different parameter sets for variable gap and transversion costs, crusta ceans group with hexapods in Tetraconata across nearly all explored parameter space, and are members of a monophyletic Mandibulata across much of the parameter space. Crustacea is non-monophyletic at low indel costs, but monophyly is favored at higher indel costs, at which morphology exerts a greater influence. The most stable higher-level crusta cean groupings are Malacostraca, Branchiopoda, Branchiura + Pentastomida, and an ostracod-cirripede group. For combined data, the Thoracopoda and Maxillopoda concepts are unsupported, and Entomostraca is only retrieved under parameter sets of low congruence. Most of the current disagreement over deep divisions in Arthropoda (e.g., Mandibulata versus Paradoxopoda or Cormogonida versus Chelicerata) can be viewed as uncertainty regarding the position of the root in the arthropod cladogram rather than as fundamental topological disagreement as supported in earlier studies (e.g., Schizoramia versus Mandibulata or Atelocerata versus Tetraconata). -
New Insects from the Earliest Permian of Carrizo Arroyo (New Mexico, USA) Bridging the Gap Between the Carboniferous and Permian Entomofaunas

Carrizoneura carpenteri gen. et sp. nov. (Syntonopteridae) demonstrates traits in hindwing venation to Lithoneura and Syntonoptera, both known from the Moscovian of Illinois. Carrizoneura represents the latest unambiguous record of Syntonopteridae. Martynovia insignis represents the earliest evidence of Mar- tynoviidae. Carrizodiaphanoptera permiana gen. et sp. nov. extends range of Diaphanopteridae previously restricted to Gzhelian. The re-examination of the type speciesDiaphanoptera munieri reveals basally coa- lesced vein MA with stem of R and RP resulting in family diagnosis emendation. Arroyohymen splendens gen. et sp. nov. (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. -
Phylogenetic Definitions in the Pre-Phylocode Era; Implications for Naming Clades Under the Phylocode
PaleoBios 27(1):1–6, April 30, 2007 © 2006 University of California Museum of Paleontology Phylogenetic definitions in the pre-PhyloCode era; implications for naming clades under the PhyloCode MiChAel P. TAylor Palaeobiology research Group, School of earth and environmental Sciences, University of Portsmouth, Portsmouth Po1 3Ql, UK; [email protected] The last twenty years of work on phylogenetic nomenclature have given rise to many names and definitions that are now considered suboptimal. in formulating permanent definitions under the PhyloCode when it is implemented, it will be necessary to evaluate the corpus of existing names and make judgements about which to establish and which to discard. This is not straightforward, because early definitions are often inexplicit and ambiguous, generally do not meet the requirements of the PhyloCode, and in some cases may not be easily recognizable as phylogenetic definitions at all. recognition of synonyms is also complicated by the use of different kinds of specifiers (species, specimens, clades, genera, suprageneric rank-based names, and vernacular names) and by definitions whose content changes under different phylogenetic hypotheses. in light of these difficulties, five principles are suggested to guide the interpreta- tion of pre-PhyloCode clade-names and to inform the process of naming clades under the PhyloCode: (1) do not recognize “accidental” definitions; (2) malformed definitions should be interpreted according to the intention of the author when and where this is obvious; (3) apomorphy-based and other definitions must be recognized as well as node-based and stem-based definitions; (4) definitions using any kind of specifier taxon should be recognized; and (5) priority of synonyms and homonyms should guide but not prescribe. -

Published online at www.senckenberg.de/arthropod-systematics on 30.viii.2017. Editors in charge: Christian Schmidt & Klaus-Dieter Klass Abstract The female cephalothorax of Xenos vesparum (Strepsiptera, Xenidae) is described and documented in detail. The female is enclosed by exuvia of the secondary and tertiary larval stages and forms a functional unit with them. Only the cephalothorax is protruding from the host’s abdomen. The cephalothorax comprises the head and thorax, and the anterior half of the first abdominal segment. Adult females and the exuvia of the secondary larva display mandibles, vestigial antennae, a labral field, and a mouth opening. Vestiges of maxillae are also recognizable on the exuvia but almost completely reduced in the adult female. A birth opening is located between the head and prosternum of the exuvia of the secondary larva. A pair of spiracles is present in the posterolateral region of the cephalothorax. -

A Phylogenetic Analysis of the Basal Ornithischia (Reptilia, Dinosauria)
A PHYLOGENETIC ANALYSIS OF THE BASAL ORNITHISCHIA (REPTILIA, DINOSAURIA) Marc Richard Spencer A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements of the degree of MASTER OF SCIENCE December 2007 Committee: Margaret M. Yacobucci, Advisor Don C. Steinker Daniel M. Pavuk © 2007 Marc Richard Spencer All Rights Reserved iii ABSTRACT Margaret M. Yacobucci, Advisor The placement of Lesothosaurus diagnosticus and the Heterodontosauridae within the Ornithischia has been problematic. Historically, Lesothosaurus has been regarded as a basal ornithischian dinosaur, the sister taxon to the Genasauria. Recent phylogenetic analyses, however, have placed Lesothosaurus as a more derived ornithischian within the Genasauria. The Fabrosauridae, of which Lesothosaurus was considered a member, has never been phylogenetically corroborated and has been considered a paraphyletic assemblage. Prior to recent phylogenetic analyses, the problematic Heterodontosauridae was placed within the Ornithopoda as the sister taxon to the Euornithopoda. The heterodontosaurids have also been considered as the basal member of the Cerapoda (Ornithopoda + Marginocephalia), the sister taxon to the Marginocephalia, and as the sister taxon to the Genasauria. To reevaluate the placement of these taxa, along with other basal ornithischians and more derived subclades, a phylogenetic analysis of 19 taxonomic units, including two outgroup taxa, was performed. Analysis of 97 characters and their associated character states culled, modified, and/or rescored from published literature based on published descriptions, produced four most parsimonious trees. Consistency and retention indices were calculated and a bootstrap analysis was performed to determine the relative support for the resultant phylogeny. The Ornithischia was recovered with Pisanosaurus as its basalmost member. -
Formation of the Entognathy of Dicellurata, Occasjapyx Japonicus (Enderlein, 1907) (Hexapoda: Diplura, Dicellurata)
S O I L O R G A N I S M S Volume 83 (3) 2011 pp. 399–404 ISSN: 1864-6417 Formation of the entognathy of Dicellurata, Occasjapyx japonicus (Enderlein, 1907) (Hexapoda: Diplura, Dicellurata) Kaoru Sekiya1, 2 and Ryuichiro Machida1 1 Sugadaira Montane Research Center, University of Tsukuba, Sugadaira Kogen, Ueda, Nagano 386-2204, Japan 2 Corresponding author: Kaoru Sekiya (e-mail: [email protected]) Abstract The development of the entognathy in Dicellurata was examined using Occasjapyx japonicus (Enderlein, 1907). The formation of entognathy involves rotation of the labial appendages, resulting in a tandem arrangement of the glossa, paraglossa and labial palp. The mandibular, maxillary and labial terga extend ventrally to form the mouth fold. The intercalary tergum also participates in the formation of the mouth fold. The labial coxae extending anteriorly unite with the labial terga, constituting the posterior region of the mouth fold, the medial half of which is later partitioned into the admentum. The labial appendages of both sides migrate medially, and the labial subcoxae fuse to form the postmentum, which posteriorly confines the entognathy. The entognathy formation in Dicellurata is common to that in another dipluran suborder, Rhabdura. The entognathy of Diplura greatly differs from that of Protura and Collembola in the developmental plan, preventing homologization of the entognathies of Diplura and other two entognathan orders. Keywords: Entognatha, comparative embryology, mouth fold, admentum, postmentum 1. Introduction The Diplura, a basal clade of the Hexapoda, have traditionally been placed within Entognatha [= Diplura + Collembola + Protura], a group characterized by entognathy (Hennig 1969). However, Hennig’s ‘Entognatha-Ectognatha System’, especially the validity of Entognatha, has been challenged by various disciplines. -

GRAENING1, YANA SHCHERBANYUK2 & MARYAM ARGHANDIWAL3 Department of Biological Sciences, California State University, Sacramento 6000 J Street, Sacramento, CA 95819-6077. E-mail: [email protected]; [email protected]; [email protected] Abstract The first checklist of California dipluran taxa is presented with annotations. New state and county records are reported, as well as new taxa in the process of being described. California has a remarkable dipluran fauna with about 8% of global richness. California hosts 63 species in 5 families, with 51 of those species endemic to the State, and half of these endemics limited to single locales. The genera Nanojapyx, Hecajapyx, and Holjapyx are all primarily restricted to California. Two species are understood to be exotic, and six dubious taxa are removed from the State checklist. Counties in the central Coastal Ranges have the highest diversity of diplurans; this may indicate sampling bias. Caves and mines harbor unique and endemic dipluran species, and subterranean habitats should be better inventoried. Only four California taxa exhibit obvious troglomorphy and may be true cave obligates. In general, the North American dipluran fauna is still under-inven- toried. Since many taxa are morphologically uniform but genetically diverse, genetic analyses should be incorporated into future taxonomic descriptions. -

By exfernal observations of these eggs ,we presented several features of of the egg structure and embryogenesis. The egg is snow-white in colo r, nearly spherical with a Iong diameter of about 130μm , and furnished with numerous ,various-sized and -shaped protub 巴rances on its surface. The newly formed blastoderm blastoderm is extraordinarily thick. On the inner side of the blastoderm at the ventral side ,a pair of cellular aggregations , which may be involved in the mesoderm segregation , is formed. The differentiated germ band is long enough to almost occupy the egg circumference. The blastokinesis is a simple flection of the embryo. The egg period is speculated speculated to be about two months. The extraordinarily thick ,early blastoderm and manner of mesoderm segregation shown in this species may be unique in Hexapoda. The long germ band and simple blastokinesis are features common to to those of other entognathans.
