New evolutionary evidence of Grylloblattida from the Middle Jurassic of Inner Mongolia, north-east China (Insecta, Polyneoptera)

The small modern insect order Grylloblattida has an abundant fossil record during the Late Palaeozoic and the Mesozoicirca. The relationships between these fossil taxa and the modern grylloblattids remain unclear because most of them are based on isolated wings or have poorly preserved body features. Modern grylloblattids are wingless insects. The new grylloblattid family Plesioblattogryllidae fam. nov. is erected for the new genus and species Plesioblattogryllus magnificus gen. nov., sp. nov. , from the Middle Jurassic of north-eastern China. The well-preserved specimen provides further evidence that could support its close relationships with the modern grylloblattids: (1) several very similar head structures, e.g. developed laciniae with inner row of setae, maxillary palps segmented into five, labial palps segmented into three, large labrum, and morphology of antenna; (2) paired eoplantulae on tarsomeres 1–4; (3) long ovipositor and large eggs comparable with those of modern taxa. The new genus has strongly developed mandibles with sharp pointed apical teeth and strong marginal teeth, and strong hook-like fore claws with basal teeth, suggesting it was carnivorous. The major differences between the extinct and extant Grylloblattida, such as the lack of wings, the eyes and ocelli either degenerated or absent, and the thorax degenerated in the modern forms, are probably related to their adaptation to their life under rocks and rock-crawler habits.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 152 , 17–24.     

An evolutional special case in the lower Orthorrhapha: some attractive fossil flies from the Middle Jurassic of China (Insecta: Diptera: Brachycera)

More than ten extinct Lower Brachycera families have been discovered throughout the world. These fossil records are of great significance in piecing together jigsaw puzzles of evolution for the Order Diptera. However, the distinct systematic relationships of the Diptera, one of the four largest orders, remain obscure. Herein, we erect a new family to enhance our systematic understanding of the Diptera. The Uranorhagionidae fam. nov. is a bewildering new extinct family comprising two new genera, Uranorhagio gen. nov. and Strenorhagio gen. nov. , and five new species, Uranorhagio daohugouensis sp. nov. , Strenorhagio deviatus sp. nov. , Strenorhagio grimaldi sp. nov. , Strenorhagio asymmetricus sp. nov. , and Strenorhagio conjugovenius sp. nov. , from the Middle Jurassic of China. Members of the new family are moderate to large in size and robust in shape. This family possesses a peculiar shape of vein R₂₊₃, the basal part of which is strongly fornical and nearly geniculate, and has the crossvein r–m at variable position. Furthermore, the Uranorhagionidae fam. nov. exhibits a mixture of distinct characters of two families in two disparate superfamilies, i.e. Rhagionemestriidae (Nemestrinoidea) and Rhagionidae (Tabanoidea), thus suggesting that this family might be in an inclusive position in dipteran phylogeny. We tentatively place this new family as a member of Tabanoidea, pending the discovery of more fossil specimens and further study. The comparison between the new family and other relative families will be discussed. © 2010 The Linnean Society of London, Zoological Journal of the Linnean Society, 2010, 158 , 563–572.

(Anisopodidae), Procramptonomyia ponomarenkoi sp. nov. and P. kovalevi sp. nov. (Procramptonomyiidae) are described from the Upper Jurassic deposits of Mongolia (Shar Teg); some features of Archirhyphus asiaticus Rohdendorf, 1964 are revealed. The latter two species are also known from the locality of Karatau (Kazakhstan, J_2/3). The genus Tega Blagoderov, Krzemi??ska, and Krzemi??ski, 1993 is transferred from the family Cramptonomyiidae into Anisopodidae (Teginae subfam. nov.).     

New species of Praeichneumonidae (Hymenoptera,Ichneumonoidea) from the Lower Cretaceous of Transbaikalia

Three new species of the fossil Lower Cretaceous family Praeichneumonidae are described from the Lower Cretaceous of Transbaikalia (Russia, Buryatia, Khasurty locality): Praeichneumon dzhidensis sp. nov., P. khamardabanicus sp. nov., and P. zakhaaminicus sp. nov. One poorly preserved specimen, Praeichneumon sp., is described. Rudiments of the second anal vein A2 and internal vein a₁–a₂ and bullae in crossveins of the fore- and hindwing are described in Praeichneumonidae for the first time.     

A New Neotropical Genus and Species of Odontocerinae (Trichoptera: Odontoceridae) from Southeastern Brazil

Anastomoneura gen. nov. and A. guahybae sp. nov. are described and illustrated based on adult male and female specimens from the Mantiqueira mountain range, Minas Gerais State. This is the third genus recorded of the family Odontoceridae from South America. The new genus is characterized by the forewing anastomosis of veins R₄ and R₅ and male genitalia with a unique, tubular, projection dorsad to the plates of tergite X.     

Provannid and provannid‐like gastropods from the Late Cretaceous cold seeps of Hokkaido (Japan) and the fossil record of the Provannidae (Gastropoda: Abyssochrysoidea)

A fauna of provannid and provannid‐like shells is described from Upper Cretaceous seep carbonates in Hokkaido, Japan. We describe two new provannid species, Provanna tappuensis sp. nov. and Desbruyeresia kanajirisawensis sp. nov. , with preserved protoconchs of unquestionable provannid type with decollate apex. This material confirms the occurrence of Provannidae as early as the Middle Cenomanian. We also describe Hokkaidoconcha gen. nov. and a new family Hokkaidoconchidae fam. nov. , with two named species, H. hikidai sp. nov. and H. tanabei sp. nov . Hokkaidoconchidae are possibly related to the Provannidae, judging from a similar, but not decollate larval shell, although the juvenile teleoconch whorls differ in being of a general cerithimorph appearance and the details of the aperture are unknown. Furthermore, we review the published fossil record of Provannidae and Abyssochrysidae, and we consider that in those older than the Eocene, there is no evidence preserved that unequivocally supports a position there. The Jurassic Acanthostrophia acanthica from Italy seems to be the oldest known record of Abyssochrysidae, and the most reliable occurrence of the family, older than from the Miocene. Other fossil, pre‐Miocene species that have been classified in the Abyssochryssidae are provisionally referred to Hokkaidoconchidae. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 154 , 421–436.

New genera and species of coelacanths from the Bear Gulch Limestone (Lower Carboniferous) of Montana (U.S.A.)

Four new species of coelacanths (Actinistia) from the Namurian E2b marine Bear Gulch Limestone of Montana are described, and a fifth species, originally described as an actinopterygian, is redescribed. Two new suborders are diagnosed. The taxonomy is: Suborder Coelacanthocdei, family Rhabdodermatidae, Caridosuctor populosum nov. sp., suborder Hadronectoroidei nov., family Hadronectoridae nov., Hadronector donbairdi nov. sp., Polyosteorhynchus simplex nov. sp. and Allenypterus montanusMelton. Lochmocercus aciculiodontus nov. sp. is incertae sedis.     

Three distinct but rare kovalevisargid flies from the Jurassic Daohugou biota,China (Insecta,Diptera, Brachycera,Kovalevisargidae)

Abstract: Three nearly complete male specimens of kovalevisargid flies are described as Kovalevisargus macropterus sp. nov., K. brachypterus sp. nov. and Kerosargus sororius sp. nov. (family Kovalevisargidae) from the Callovian–Oxfordian Daohugou biota in Inner Mongolia, China. These extend the range of the family Kovalevisargidae outside of Central Asia for the first time, reveal new morphological details about kovalevisargid flies and offer new evidence for the biostratigraphic correlation of nonmarine sedimentary strata of both the Karabastau and Daohugou Formations. Close similarities in the composition of insect taxa from both entomofaunas imply not only the geological age but also the sedimentary environment at that time being the same, or nearly so. Familial and generic diagnoses of kovalevisargid flies are supplemented based on information derived from these new species.     

Seminibacterium arietis gen. nov., sp. nov., isolated from the semen of rams

Two gram-negative, catalase- and oxidase-positive, bacillus-shaped bacterial strains were isolated from the semen of two rams. 16S rRNA gene sequencing demonstrated that both isolates represented a distinct subline within the family Pasteurellaceae with <95% sequence similarity to any recognized member of this family. Sequencing of rpoB and infB genes confirmed this finding with the semen isolates representing a new sub-line within the family Pasteurellaceae. The main cell fatty acids of strain DICM-00342^T were C_14:0, C_16:0, C_18:1ω7c and summed feature 3 (C_16:1ω7c/iso-C_15:0 2OH). Ubiquinone Q-8 was the major quinone and 1,3-diaminopropane was the predominat polyamine. Major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. The new genus can be phenotypically distinguished from currently described genera of this family based on physiological traits and a combination of signature amino acids in the RpoB protein sequence. On the basis of these results we describe a new genus and species for which we propose the name of Seminibacterium arietis gen. nov., sp. nov. (DICM11-00342^T = CCUG 61707^T = CECT 8033^T).     

Mesozoic leaf beetles of the tribe Mesolpinini trib. nov. (Coleoptera,Chrysomelidae) from the Lower Cretaceous

This publication is based on recent studies of Lower Cretaceous leaf beetles from the Yixian Formation (Liaoning, China), which are represented by five new species of one new genus Mesolpinus gen. nov. (M. antenattus sp. nov. [type species], M. adapertilis sp. nov., M. angusticollis sp. nov., M. basicollis sp. nov., and M. trapezicollis sp. nov.) assigned to a new tribe, Mesolpinini trib. nov. of the subfamily Chrysomelinae. This tribe, which includes only species from the Jehol biota, is the oldest known group of the family in the fossil record. A key to species of the genus Mesolpinus gen. nov. is provided and the position of the new tribe is discussed. A brief overview of the Mesozoic data on the subfamily Chrysomeloidea is given.
