On the tachinid fauna of the southeastern part of European Russia (Diptera,Tachinidae)

A list of tachinids (Diptera, Tachinidae) of the southeastern European part of Russia comprising 74 species is given. Eight species (Bithia jacentkovskyi, Estheria bohemani, Zeuxia nudigena, Stomina iners, Opesia descendens, Labigastera pauciseta, Cylindromyia rufifrons, Besseria reflexa) are for the first time recorded from Russia, three species (Acemya rufitibia, Atylomyia loewi, Crapivnicia donabilis), from the European part of Russia, and 25 species, from the southeastern European part of Russia. The male of Crapivnicia donabilis Richter found in Astrakhan Province is described. The genus Crapivnicia Richter is assigned to the tribe Goniini, based on the examination of the abdomen of C. donabilis female from Kalmykia which has shown the presence of dark microtype eggs.     

New taxa of Mesorthopteridae (Insecta: Grylloblattida) from the Permian of Russia

Aphilenia hauseri Wse. is a new synonym of A. unicolor Rtt.; A. inornata Chen is transferred to the genus Chloropterus.     

The genus <Emphasis Type="Italic">Osmoderma</Emphasis> (Coleoptera,Scarabaeidae, Trichiinae) in Siberia and the Russian Far East

A review of the species of the genus Osmoderma of Siberia and the Russian Far East is given. The species Osmoderma opicum coreanum Tauzin, 2013 was first identified in the fauna of Russia. The locality of O. davidis Fairmaire, 1887 in Buryatia, which was confirmed by material, is presented. The distribution of the East Asian species of this genus in the territory of Russia is analyzed in detail. The data on the phenology, trophic associations, and topical preferences are considered.     

The genus <Emphasis Type="Italic">Copris</Emphasis> (Coleoptera,Scarabaeidae) in the Far East of Russia

The species of the genus Copris of the Russian Far East are reviewed. Copris tripartitus Waterhouse, 1875 is recorded for the fauna of Russia for the first time. The distribution of the Eastern Asian species of this genus in Russia is analyzed in detail. The data on their phenology, trophic associations, and habitat preferences are considered.     

Analysis of the species composition of the genus <Emphasis Type="Italic">Chrysopilus</Emphasis> (Diptera,Rhagionidae) in the Eastern Palaearctic Region

The species of the genus Chrysopilus, inhabiting Russia and adjacent territories, are analyzed for the first time. The structure of the genitalia is examined, and new diagnostic characters of the species are given. Some species from the boundary areas are considered in detail, since the species composition of the genus has been poorly studied there. The data on 11 species distributed in eastern Russia and Japan are given.     

On the distribution of seed-eating <Emphasis Type="Italic">Dicraeus nartshukae</Emphasis> (Diptera,Chloropidae) and its host plant <Emphasis Type="Italic">Leymus mollis</Emphasis>

The distribution ranges of Dicraeus nartshukae Kanmiya (Diptera, Chloropidae) and its host plant Leymus mollis (Trin.) Pilger are discussed. Larvae of D. nartshukae develop in unripe seeds of Leymus mollis but not in the seeds of the closely related L. villosissimus and L. interior. The spikes, spikelets, and glumes of L. mollis are larger than in other species, and usually softly hirsute. The glumes of L. villosissimus and L. interior possess dense hirsute pubescence which appears to be unfavorable for oviposition of Dicraeus nartshukae. The absence of seedeating Dicraeus on L. villosissimus and L. interior is an additional argument in support of distinctness of these species. The distribution range of Dicraeus nartshukae is meridional, or Pacific littoral.     

The species composition and ecological features of pea crabs of the genus <Emphasis Type="Italic">Pinnixa</Emphasis> White, 1846 (Brachyura: Pinnotheridae) in Peter the Great Bay,the Sea of Japan

This paper provides an overview of pea crabs of the genus Pinnixa White, 1846 (Brachyura: Pinnotheridae) that occur along the Russian coast of the Sea of Japan. Three species of the genus have been recorded for this area: P. tumida Stimpson, 1858, P. rathbuni Sakai, 1934, as well as P. banzu Komai, Nishi & Taru, 2014, which is the first record for the fauna of Russia. All species clearly differ ecologically: P. tumida was found in Posyet Bay in the intestine of the burrowing holothurian Paracaudina chilensis (Müller, 1850); P. rathbuni, in burrows of the echiuroid Urechis unicinctus (von Drasche, 1881); and P. banzu, in tubes of the polychaete Chaetopterus cautus Marenzeller, 1879. The paper also provides a definitive key to Pinnixa species and data on the size, behavior, symbionts, and parasites of P. rathbuni and P. banzu.     

A new conifer species, Mesocyparis rosanovii sp. nov. (Cupressaceae, Coniferales), and Transberingian floristic connections

A new species, Mesocyparis rosanovii sp. nov. from the Lower Paleocene of the Amur Region, Russia, is characterized by a combination of advanced and primitive features: mixed opposite-alternate branching of vegetative shoots, leafy microsporophylls, as well as a relatively high number of sporangia per microsporophyll and seeds per cone scale. The Late Cretaceous-Early Paleogene genus Mesocyparis McIver et Basinger, which obviously embraces a natural group of closely related species, was a significant component of the vegetation in the middle and high latitudes of eastern Asia and western North America. The range of the genus testifies to terrestrial Transberingian connections between the continents during the Cretaceous warming phases.     

Are Cristaria herculea (Middendorff, 1847) and Cristaria plicata (Leach, 1815) (Bivalvia,Unionidae) separate species?

The number of species in the freshwater mussel genus Cristaria Schumacher, 1817 recognized from Far East Russia has varied over the last several decades. While some authors consider the occurrence of only one species, Cristaria plicata (Leach, 1815), widespread in East Asia, others, recognize two separate species Cristaria herculea (Middendorff, 1847) and Cristaria tuberculata Schumacher, 1817 from Far East Russia, distinct from C. plicata. For the present study, freshwater mussels, identified as C. herculea, were collected in the Upper Amur basin (Transbaikalia, Russia). The shell morphology and the whole soft body anatomy were analysed in detail and compared with previously published information on other Cristaria spp.. Additionally, a cytochrome oxidase subunit 1 (CO1) gene fragment was sequenced from foot tissue samples of selected animals, collected from the same region, and compared with published data. Based upon morphological similarities of glochidia and adult morphology and anatomy as well as the mitochondrial DNA sequence analysis, we consider C. herculea as a synonym of C. plicata. Further analysis of Far East Russia C. herculea and C. tuberculata specimens using both molecular and morphological characters should be carried in the future to enhance our knowledge about the taxonomy within the Cristaria genus. Moreover, a comprehensive revision of the genus Cristaria is needed, restricting the type locality and comparing topotypic specimens for both C. plicata and C. tuberculata, and including all recognized Cristaria species.     

The first record of the shore fly Paracoenia fumosalis (Diptera, Ephydridae) in the Palaearctic region

Paracoenia fumosalis Cresson previously known only from the USA and Canada is recorded in the Palaearctic Region for the first time. The adults were collected near a thermal hydrosulfuric spring in the Geiser Valley in Kamchatka. A key to species of the genus Paracoenia occurring in Russia is given.     

Une nouvelle espèce de Podocnemis (Pleurodira, Podocnemididae) provenant du Néogène de la formation Solimões, Acre, Brésil

A Neogene turtle from Brasil is described. It represents the first find of a new species close to the extant Podocnemis sextuberculata. Both species constitute a new clade in the genus. The synapomorphies they share and the differences between them are given. P. negrii nov. sp. is the second fossil species of the genus, after P. bassleri from the Neogene of Peru, which constitutes another clade with the extant P. expansa. The relationships between these two clades and the other species of the genus are not determinate.
