New or Little-Known Beetle Species (Coleoptera) of the Families Histeridae and Scarabaeidae in the Faunas of Ciscaucasia,Western and Southeastern Kazakhstan

New data are presented on the distribution of Histeridae and Scarabaeidae in Russia and Kazakhstan. Three species, Pholioxenus schatzmayri J. Müller, 1910, Mendidaphodius linearis (Reiche et Saulcy, 1856), and Onthophagus ponticus Harold, 1883, are recorded from Kazakhstan for the first time, and one species, Atholus scutellaris (Erichson, 1834), is new to the fauna of Russia. The distribution ranges are refined for Microsaprinus therondianus (Dahlgren, 1973), Hypocacculus biskrensis (Marseul, 1876), Paravolvulus refector (Reitter, 1904), Hister megalonyx Reichardt, 1922, Bodilus longipennis (Rakovi?, 1984), Protaetia cyanescens jacobsoni (Kiseritzky, 1910), and Valgus hemipterus (Linnaeus, 1758). All these species are distributed mainly in the four zoogeographical regions: Hesperian, European, Saharo-Gobian (Sethian), and Scythian.     

New and little known crickets of the subfamily phalangopsinae (Orthoptera,Gryllidae): 5. Neotropical taxa of the tribe Paragryllini

One new genus, two new subgenera, and eight new species from Ecuador, Brazil, and Venezuela are described. The former genus Hattersleya Nischk et Otte is considered as a subgenus of the genus Neoacla Des. Acla multivenosa Chop., A. reticulata Chop., A. vicina Chop., Selvacla choreutes Otte, S. salvator Otte, S. alsiosus Otte, and S. sophos Otte are transferred to the genus Neoacla, and Desutteria epiplatys Nischk et Otte, to the genus Silvastella Des.-Gr. New data on the geographical and ecological distribution of some species are given.     

On distribution and ecology of some species of cleonines (Coleoptera,Curculionidae): IV. Genus <Emphasis Type="Italic">Lixus</Emphasis> F., subgenus <Emphasis Type="Italic">Eulixus</Emphasis> Reitt.

Data on habitats, food plants of larvae and adults, feeding, mating, oviposition, larval and pupal development, natural enemies, and distribution of seven weevil species (Lixus canescens F.-W., L. iridis Ol., L. myagri Ol., L. punctirostris Boh., L. subtilis Boh., L. incanescens Boh., and L. brevipes Bris.) are given. New host plants of L. canescens and L. iridis are revealed. Gall induction by L. brevipes is reported for the first time. Distribution of all the species in Ukraine and Russia (the latter based on the literature) are given in more detail. Information on the known and potential economic importance of every species is provided.     

On Frasnian ammonoids of the New Siberian Islands

Ammonoids from the basal beds of the Nerpalakh Formation (Lower Frasnian) of Belkovsky Island (New Siberian Archipelago) are systematically studied. Taxonomically, the assemblage studied (Manticoceras insulare sp. nov., Tornoceras typum (Sandberger, 1851), and T. contractum Glenister, 1958) is similar to the Early Frasnian ammonoid assemblage of South Timan, from which its is distinguished by the absence of the genera Timanites and Komioceras. The same beds contain conodonts of the Palmatolepis transitans Zone (= MN 4 Zone of the Montagne Noire standard succession), which allow the correlation of the beds studied with the Timanites keyserlingi and Komioceras stuckenbergi ammonoid zones of South Timan. The Early Frasnian ammonoids could supposedly have entered the region of the New Siberian Archipelago from the southwest at the time of a major transgression, which facilitated the distribution of the genera Manticoceras and Tornoceras. A new species of the genus Manticoceras is described.     

New data on the fauna,taxonomy and ecology of praying mantises (Dictyoptera,Mantodea) from Russia

Two little-known species of praying mantises, Severinia turcomaniae (Saussure, 1872) and Rivetina nana Mistshenko, 1967, are reported for the faunas of Russia and Europe for the first time based on the material collected in Astrakhan Province of Russia. New data on the morphology, ecology, and distribution of these species are given. The male genitalia of S. turcomaniae and the female of R. nana are described for the first time. The lectotype of Oxythespis turcomaniae Saussure, 1872 is designated and deposited in the collection of the Zoological Museum of the Moscow University. The synonymy of O. turcomaniae and Mantis wagneri Kittary, 1849 is shown to be insufficiently justified; M. wagneri is provisionally placed in the genus Severinia Finot, 1902. Since R. nana Lindt, 1968 is most probably not a synonym of R. nana Mistshenko, 1967 but a separate species, a substitute name R. pseudonana Shcherbakov nom. n. is proposed for the former. Some characters traditionally used for the identification of Rivetina species are shown to be significantly variable and thus unreliable. A key to 11 praying mantis species of the Russian fauna is provided. The recent discovery of S. turcomaniae and R. nana in the northern Caspian Sea region is assumed to reflect the expansion of the natural ranges of thermophilic species caused by increasing aridity of the climate.     

New data on the taxonomy,distribution, and ecology of the weevil genus <Emphasis Type="Italic">Otiorhynchus</Emphasis> germar (Coleoptera,Curculionidae)

The subgenus Pocusogetus Rtt. of the genus Otiorhynchus Germ. is revised.

Fisht, the Western Caucasus). O. fischtensis is transferred from the subgenus Vicoranius Rtt., its lectotype is designated. A key to species of Pocusogetus is given. The systematic position of the subgenera Pocusogetus and Vicoranius in the genus Otiorhynchus is discussed. New data on the geographical distribution and ecology of the little-known species of the subgenera Obvoderus Rtt., Pseudoprovadilus Magnano, and Clypeorhynchus Yunakov et Arzanov are given. Some features of ecological differentiation between Otiorhynchus species in the alpine and subalpine zones of the Caucasus are discussed.

New data on the taxonomy and morphology of weevils of the genus <Emphasis Type="Italic">Plinthus</Emphasis> (Coleoptera,Curculionidae)

The taxonomic composition of the genus Plinthus Germar, 1817 is considered. The procedure of dissection of the weevil genitalia, variations in the endophallus armature, proventriculus, and crop in Plinthus species are described, and the terminology for these structures is explained.

New data on the taxonomy, morphology, and distribution of species from the subgenera Plinthomeleus Reitter, 1913 and Plinthus s. str. are presented. Keys to the subgenera of Plinthus and to species groups of the subgenus Plinthomeleus are given. Plinthus squalidus is recorded from the Caucasus and Russia for the first time.     

Mesozoic rissoid gastropods: History of the study,systematics, and diversity

The history of the study and review of generic and species diversity of Mesozoic rissoid gastropods are provided. The generic composition of Jurassic rissoid gastropods is revised, so that it is proposed to regard them as the family Rissoidae, comprising the genera Bralitzia, Buvignieria, Palaeoceratia, and Palaeorissoina. It is tentatively proposed to assign the genus Hudlestoniella to Rissoidae; this is caused by insufficient morphological knowledge of this genus. The family Palaeorissoidae is regarded as a synonym of Rissoidae. Stratigraphical and geographical distribution of Rissoidae genera is reviewed. From the Jurassic of European Russia, the following species of the genus Buvignieria are described: B. calloviana Gründel, B. imminuera Gründel, B. paucicostata Gründel, B. eichwaldiana (Rouillier), B. choroshovensis Gerasimov, and B. gruendeli sp. nov. The morphological characteristics and stratigraphical distribution of these species are provided. Based on extensive material, the taxonomic significance of particular conchological characters for the establishment of species is discussed.     

New sepulcids (Hymenoptera: Sepulcidae) from the Lower Cretaceous of Asia: II. Ghilarellinae and Trematothoracinae

Five new species of sepulcids (Hymenoptera: Sepulcidae) are described from the Lower Cretaceous of Transbaikalia and Mongolia (localities Khasurty, Baissa, and Bon-Tsagan). The new species belong to the subfamilies Ghilarellinae and Trematothoracinae: Ghilarella alexialis sp. nov., G. masculina sp. nov., Trematothorax zhangi sp. nov., T. brachyurus sp. nov., and T. extravenosus sp. nov. The genus Trematothoracoides Zhang et al., 2001 (syn. nov.) is synonymized with Trematothorax Rasnitsyn, 1988. A complete list of species of Sepulcidae is provided.

A key to 29 species of the hover-fly genus Paragus from Asia is given and provided with original figures of the male genitalia, abdomen, and head for each species. New data on the distribution of Paragus species are reported.     

New and little-known crickets of the subfamily phalangopsinae (Orthoptera,Gryllidae): 4. Neotropical genus <Emphasis Type="Italic">Uvaroviella</Emphasis>

The former genera Acla Heb., Aclodes Heb., and Paraclodes Des.-Grand., are considered subgenera of the genus Uvaroviella Chop. Five new subgenera and nine new species of this genus from Ecuador and Guyana are described. Two new species names are proposed due to the secondary homonymy, and one old species name was resurrected from synonymy as a replacement name. Lectotype for U. cavicola Chop. is designated. New data on the geographical and bitopical distribution of some species are given. The paper is based on the material from the collections of the Zoological Institute, Russian Academy of Sciences, St. Petersburg (ZIN), and the Natural History Museum, London (NHM).     

A review of the fauna of the subgenus <Emphasis Type="Italic">Troginus</Emphasis>, genus <Emphasis Type="Italic">Carpelimus</Emphasis> (Coleoptera,Staphylinidae), from tropical Africa

The review includes seven species, three new species are described: Carpelimus maliensis, C. neuterus, and C. xenosus spp. n. The names Trogophloeus variegatus Cameron, 1944, T. ruandanus Cameron, 1956, and Carpelimus maroccanus Gildenkov, 2004 are synonymized with Carpelimus atomus (Saulcy, 1864). Carpelimus rondaensis is downgraded to the subspecies C. boops rondaensis (Fagel, 1957). Lectotype of Trogophloeus dundoensis Cameron, 1950 is designated. New data on the morphology and distribution of Carpelimus (Troginus) species are given.     

New data on the changes in the abundance and distribution of several species of beetles (Coleoptera) in European Russia and the Caucasus

Changes in the abundance and distribution of selected species of beetles in European Russia and in the Caucasus are reported. Most of these species have been recorded from the Northwestern Caucasus in the last 10–15 years. The abundance and distribution during the last two years have changed most sharply in the introduced species, the Harlequin lady beetle Harmonia axyridis and two East Asian bruchids, Megabruchidius dorsalis and M. tonkineus. In 2016, the latter has been found in Georgia for the first time, and Harmonia axyridis was found in St. Petersburg. Abundance of the weevil Alcidodes karelinii with the range situated mostly east of the Caucasus and Volga River remains in Northwestern Caucasus at about the previous level. The flea-weevil species, a leaf miner on Ulmus pumila, misidentified previously as Orchestes mutabilis, is described in this paper as Orchestes steppensis sp. n. based on the material from Russia, Kazakhstan, Mongolia and Northern China; no its further distribution westward in 2015–2016 has been found. This species, rapidly widening its range in North America in the recent decade, is misidentified there as Orchestes alni. A key for differentiation of Orchestes alni, O. mutabilis and O. steppensis sp. n. is provided with photographs of adults of all three species. Magdalis armigera has increased abundance in Northwestern Caucasus in 2016 and was for the first time found in Northwestern Russia (Pskov Province) in 2015. Regular faunistic surveys during several decades provide a possibility of recording considerable changes in the abundance of some common species of Coleoptera, often associated with changes in their distribution.     

Distribution Peculiarities of the Sand (<Emphasis Type="Italic">Riparia riparia</Emphasis> Linnaeus 1758) Martin and the Pale Sand (<Emphasis Type="Italic">Riparia diluta</Emphasis> Sharpe et Wyatt 1893) Martin (Passeriformes,Hirundinidae) in the Sympatry Zone in Southern Central Siberia

The relationships between the sand martin (Riparia riparia Linnaeus 1758) and the pale sand martin (Riparia diluta Sharpe et Wyatt 1893) in sympatric conditions in southern Central Siberia are discussed. New data on the distribution patterns of these two closely related martin species in the study area, the location of the breeding colonies, and nesting in mixed-species colonies are presented. Information on the morphology and habitat preferences of R. riparia and R. diluta, including conesting species, is provided. In the sympatry zone in southern Central Siberia, the pale sand martin is shown to be more abundant, with mixed colonies of R. riparia and R. diluta also being found. Both species studied differ significantly in the morphometric characters. When looking for the location of a breeding colony, R. riparia and R. diluta display different habitat requirements.
