Mesozoic Trachypachidae (Insecta: Coleoptera) from China

Abstract: Four well‐preserved beetles, attributed to Eodromeinae within Trachypachidae, are described from the Mesozoic of Inner Mongolia, China. Eodromeus robustus sp. nov., E. daohugouensis sp. nov. and Unda chifengensis sp. nov. are from the Middle Jurassic of Daohugou. The diagnostic characters for the two genera are revised, and all species of these genera are keyed. A new genus and species, Sinodromeus liutiaogouensis gen. nov., sp. nov., is described from the Lower Cretaceous Yixian Formation of Liutiaogou. The current fossil records of Trachypachidae from China are reviewed, and only five species (four described here) can be convincingly attributed to this family. The morphological disparity of Mesozoic Eodromeinae suggests that they evolved a broad spectrum of locomotory lifestyles.     

Pronemouridae fam. nov. (Insecta: Plecoptera), the stem group of nemouridae and notonemouridae,from the Middle Jurassic of Inner Mongolia,China

Abstract: A new family, Pronemouridae fam. nov., with a new genus, Pronemoura gen. nov., and five new species of fossil stoneflies are described from Daohugou village (Middle Jurassic), Inner Mongolia, China: P. shii sp. nov., P. angustithorax sp. nov., P. longialata sp. nov., P. minuta sp. nov. and P. peculiaris sp. nov. Wing venation of pronemourinids presents some or considerable variety in the fore and hind wings of the same or different individuals. Pronemourinidae, retaining plesiomorphic characters (short, multisegmented cerci and CuA with forks), should be treated as the stem group of Nemouridae and Notonemouridae. Based on fossil data, we propose a model in which the extant plecopterid distribution began in the Early Cretaceous. Nemouridae and Notonemouridae must have occurred in Asia and begun to migrate from here by at least the Early Cretaceous.     

New Phoenicopsis leaves (Czekanowskiales) from the Middle Jurassic Daohugou Biota,China and their roles in phytogeographic and paleoclimatic reconstruction

The Middle Jurassic Jiulongshan Formation, distributed in the Daohugou area, Ningcheng County, Inner Mongolia, China, is famous for yielding abundant, well-preserved fossil vertebrates and invertebrates. However, only a few fossil plants have been reported to date. In this paper, one new species of Czekanowskiales, Phoenicopsis (Windwardia) daohugouensis n. sp. is described based upon leaf morphology and epidermal characters. The new species represents the first record of Czekanowskiales from the Daohugou Biota. The discovery of the new species reveals the significance of the Daohugou flora as one of the deciduous forests in the temperate-warm temperate zone of Eurasia during the Middle Jurassic.     

Phylogenetic relationships of the Mesozoic paraneopteran family Archipsyllidae (Insecta: Psocodea)

The Middle Jurassic Archipsylla sinica sp. n. is the first record of the enigmatic Mesozoic family Archipsyllidae from China. This well-preserved Chinese material bears several apomorphies allowing an attribution of this family to the Psocodea. The presence of four-segmented tarsi in Archipsyllidae suggests that the reduction in number of tarsomeres occurred independently at least two times in the modern paraneopteran lineages Psocodea (“Psocoptera” + Phthiraptera) and Condylognatha (Thysanoptera + Hemiptera).     

A Redescription of Climacostomum virens (Ehrenberg) Stein and Proposal of a New Heterotrich Ciliate Family, Climacostomidae fam. n.

SYNOPSIS. Structure of the vegetative and asexually dividing forms of the large ciliate Climacostomum virens is redescribed with emphasis on stomatogenesis. These findings are discussed in relation to the taxonomic and possible evolutionary position of Climacostomum among heterotrichous ciliates. Comparative considerations of the buccal and somatic structures as well as of the stomatogenic patterns in this and other closely related ciliate genera indicate the need for placing Climacostomum and Fabrea in a new family, CLIMACOSTOMIDAE . The morphologic evidence suggests that Climacostomum may represent a line linking Fabrea and Stentor.     

New fossil hangingflies (Insecta: Mecoptera: Raptipedia: Cimbrophlebiidae) from the Middle Jurassic of Inner Mongolia,China

Abstract: Two new genera with six new species of hangingflies (Mecoptera: Raptipedia: Cimbrophlebiidae) are described. They were collected from the Middle Jurassic nonmarine sedimentary strata of the Jiulongshan Formation in Daohugou, Inner Mongolia, north‐eastern China. This report of Cimbrophlebiidae from the Yanliao Biota provides detailed morphological information and evidence of a broad diversity of Cimbrophlebiidae during the Middle Jurassic. A key to the known species of Cimbrophlebiidae is provided.     

On taxonomy and distribution of fossil Cerophytidae (Coleoptera: Elateriformia) with description of a new Mesozoic species of Necromera Martynov 1926

In this paper the data on fossils of the family Cerophytidae are reviewed. New synonymy on generic names Necromera Martynov 1926 (proposed in composition of the family Oedemeridae); Idiomerus Dolin in Dolin et al. 1980, n. syn. (proposed in composition of Elateridae) and Leptocnemus Hong & Wang 1990, n. syn. (proposed without any family attribution) is established. New materials on this family from Mesozoic deposits of Asia are cited. As a result, it was established that this spreads in deposits of both Upper Jurassic and Lower Cretaceous. Mercata festira Lin 1986 described from Lower Jurassic as member of Silphidae and Abrotus reconditus Dolin in Dolin et al. 1980 described from Upper Jurassic as a member of Elateridae are transferred to Cerophytidae. Diagnoses of the genus Necromera and family Cerophytidae in compression fossils are elaborated. Necromera admiranda n. sp. is described from the Upper Jurassic-Lower Cretaceous in Liaoning, China. The historical development of the family from the Lower Jurassic is discussed.     

A new genus of Elateriform beetles (Coleoptera,Polyphaga) from the Middle-Late Jurassic of Karatau

A new coleopteran genus, Anacapitis gen. nov., comprising A. karataviensis sp. nov., A. incertus sp. nov., and A. oblongus sp. nov., is described from the Karabastau Formation of the Karatau locality (southern Kazakhstan, Middle-Late Jurassic) in the infraorder Elateriformia. The systematic position of the new genus within the suborder Polyphaga is discussed.     

A new,well-preserved genus and species of fossil Glaphyridae (Coleoptera,Scarabaeoidea) from the Mesozoic Yixian Formation of Inner Mongolia,China

A new genus and species of fossil Glaphyridae, Cretohypna cristatagen. et sp. n., is described and illustrated from the Mesozoic Yixian Formation. This new genus is characterized by the large body; large and strong mandibles; short labrum; elytra without longitudinal carina; and male meso- and possible metatibia apically modified. A list of described fossil glaphyrids of the world is provided. This significant finding broadens the known diversity of Glaphyridae in the Mesozoic China.     

Two new false click-beetles from China (Coleoptera: Elateroidae: Eucnemidae)

Thambus planifrons Muona & Meng sp. nov. and Otho rutriclypeus Muona & Meng sp. nov. are described from China. Both genera are recorded for the first time from China. Except for the European T. friwaldszkyi Bonvouloir, 1871, and the Japanese T. curvicaria Hisamatsu, 1956, all other previously known species belonging to Otho were from the Americas. Eight Otho species have been described from disparate parts of Asia earlier.urn:lsid:zoobank.org:pub:10B667F6-F11E-454B-9653-D66A2D7ABFA1.     

A new lasiosynid beetle from the Middle Jurassic of China with remarks on the systematic position of Lasiosynidae

A new beetle species, Lasiosyne laxa n. sp., is described from the Jurassic Daohugou deposits in Inner Mongolia, China. Its morphological significance and systematic position within the genus Lasiosyne Kirejtshuk et al., 2010a, Kirejtshuk et al., 2010b and the family Lasiosynidae are discussed. The research history of Lasiosynidae is summarized for the first time. The affiliation of Lasiosynidae to the superfamily Byrrhoidea is discussed in detail.     

Tettigarctidae (Insecta: Hemiptera: Cicadoidea) from the Middle Jurassic of Inner Mongolia, China

Three new species of Tettigarctidae from the Middle Jurassic of Daohugou, China are described: Shuraboprosbole daohugouensis nov. sp., S. minuta nov. sp., and S. media nov. sp. The revised diagnostic characters of Shuraboprosbole Becker-Migdisova are provided based on well-preserved whole-bodied fossil tettigarctids. So far, only four definitive species of Tettigarctidae are recorded from the Mesozoic of China. The pronotum concealing major of mesonotum seems to be an autapomorphy of Tettigarctinae. The “cicadellid-like tarsi” found in Cicadellidae and Brazilian Tettigarctidae are probably a parallel evolution.

Phylogenetic analysis of the minute brown scavenger beetles (Coleoptera: Latridiidae), and recognition of a new beetle family,Akalyptoischiidae fam.n. (Coleoptera: Cucujoidea)

We infer the first phylogenetic hypothesis for Latridiidae Erichson (Coleoptera: Cucujoidea). Portions of seven genes (18S ribosomal DNA, 28S ribosomal DNA, 12S ribosomal DNA, 16S ribosomal DNA, cytochrome c oxidase I and II and histone III) were analysed. Twenty‐seven latridiid species were included, representing both subfamilies and more than half of the currently recognized genera. Eight outgroup taxa from other families of Cucujoidea were included. Parsimony and partitioned Bayesian analyses were performed on the combined dataset. In both phylogenetic analyses, the enigmatic Akalyptoischion Andrews (Latridiinae) was recovered outside of Latridiidae. The subfamilies Corticariinae and Latridiinae (without Akalyptoischion) were each recovered as monophyletic in both analyses. A new family, Akalyptoischiidae fam.n. is erected based on the results of the phylogenetic study and further support from adult morphology, key features of which are illustrated.
