With an estimated age of at least 140 million years, the cave crickets (Rhaphidophoridae) form the oldest exclusively wingless lineage within the long-horned grasshoppers (Ensifera). With respect to their morphology, cave crickets are generally considered to represent a 'primitive' group of Ensifera, for which no apomorphic character has been reported so far. Results: We present the first detailed investigation and description of the thoracic skeletal and muscular anatomy of the East Mediterranean cave cricket Troglophilus neglectus (Ensifera: Rhaphidophoridae). T. neglectus possesses sternopleural muscles that are not yet reported from other neopteran insects. Cave crickets in general exhibit some unique features with respect to their thoracic skeletal anatomy: an externally reduced prospinasternum, a narrow median sclerite situated between the meso-and metathorax, a star-shaped prospina, and a triramous metafurca. The thoracic muscle equipment of T. neglectus compared to that of the bush cricket Conocephalus maculatus (Ensifera: Tettigoniidae) and the house cricket Acheta domesticus (Ensifera: Gryllidae) reveals a number of potentially synapomorphic characters between these lineages. Conclusions: Based on the observed morphology we favor a closer relationship of Rhaphidophoridae to Tettigoniidae rather than to Gryllidae. In addition, the comparison of the thoracic morphology of T. neglectus to that of other wingless Polyneoptera allows reliable conclusions about anatomical adaptations correlated with secondary winglessness. The anatomy in apterous Ensifera, viz. the reduction of discrete direct and indirect flight muscles as well as the strengthening of specific leg muscles, largely resembles the condition found in wingless stick insects (Euphasmatodea), but is strikingly different from that of other related wingless insects, e.g. heel walkers (Mantophasmatodea), ice crawlers (Grylloblattodea), and certain grasshoppers (Caelifera). The composition of direct flight muscles largely follows similar patterns in winged respectively wingless species within major polyneopteran lineages, but it is highly heterogeneous between those lineages."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2016"],["dc.identifier.doi","10.1186/s12862-016-0612-5"],["dc.identifier.isi","000370324600001"],["dc.identifier.pmid","26891721"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13485"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41366"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Biomed Central Ltd"],["dc.relation.issn","1471-2148"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","The thorax of the cave cricket Troglophilus neglectus: anatomical adaptations in an ancient wingless insect lineage (Orthoptera: Rhaphidophoridae)"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Here we report a novel egg-deposition mode for Phasmatodea performed by an undescribed Vietnamese species of the enigmatic subfamily Korinninae that produces a complex egg case (ootheca), containing numerous eggs in a highly ordered arrangement. This novel egg-deposition mode is most reminiscent of egg cases produced by members of unrelated insect orders, e. g. by praying mantises (Mantodea) and tortoise beetles (Coleoptera: Cassidinae). Ootheca production constitutes a striking convergence and major transition in reproductive strategy among stick insects, viz. a shift from dispersal of individual eggs to elaborate egg concentration. Adaptive advantages of ootheca formation on arboreal substrate are likely related to protection against parasitoids and desiccation and to allocation of specific host plants. Our phylogenetic analysis of nuclear (28S, H3) and mitochondrial (COI, COII) genes recovered Korinninae as a subordinate taxon among the species-rich Necrosciinae with Asceles as sister taxon, thus suggesting that placement of single eggs on leaves by host plant specialists might be the evolutionary precursor of ootheca formation within stick insects."],["dc.identifier.doi","10.1038/srep07825"],["dc.identifier.isi","000347903800006"],["dc.identifier.pmid","25592976"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13640"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/38164"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","2045-2322"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Extreme convergence in egg-laying strategy across insect orders"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The present study provides a detailed comparative investigation of the skeletal and muscular thoracic morphology of 23 orthopteran species. For the first time, we investigate unstudied ensiferan key taxa including Gryllacrididae (raspy crickets), Stenopelmatidae (Jerusalem crickets), and Prophangalopsidae (hump-winged crickets). We identify novel thoracic characters that might represent apomorphies of Orthoptera: the connection of propleura and prosternum as pleurosternal bridge, the pterothoracic furcae that enclose the respective pleural arm from the ventral side, the mesofurca and mesospina that are situated in a single line along the sternacosta, and a stalked mesospina with a delimited dorsal plate. In particular, the morphology of the sternal apophyses turned out to show major differences between the two major subgroups of Orthoptera: Caelifera (short-horned grasshoppers) and Ensifera (long-horned grasshoppers). For example, the profurca bears a single arm in Caelifera and is branched in the majority of Ensifera. A number of thoracic muscles, like the Musculus mesofurca-propleuralis (IIspm9), could be identified and defined for Orthoptera, muscles that have never been described before to be present in other neopteran insects. Additionally, the obtained data set is used to reconstruct the orthopteran ground pattern of the thoracic skeletomuscular complex. Moreover, all characters potentially containing phylogenetic information are discussed and compiled in a morphological character matrix in order to be accessible for future phylogenetic studies."],["dc.identifier.doi","10.1093/isd/ixx006"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/57679"],["dc.language.iso","en"],["dc.title","Comparative Morphology of the Orthopteran Thorax With a Discussion of Phylogenetically Relevant Characters"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]
