Upper Devonian conodonts of northeastern European Russia

The conodont succession in the Upper Devonian facially different sections of northeastern European Russia (Chernyshev Ridge, Subpolar and Polar Urals, Pai-Khoi) are studied. The sections are subdivided and correlated taking into account the global standards for stages. The Frasnian Montagne Noire zonation (Klapper, 1989) is used for the first time for northeastern European Russia; the authors correlated this zonation with the scale of Ziegler and Sandberg (1990). Famennian deposits are subdivided using scale of Ziegler and Sandberg (1984) and miospore zonation. The age of local geological units (formations) is specified; the formations of different regions of northeastern European Russia are correlated to each other and to the regional subdivisions of EEP and Southern Urals. A total of 93 species of Ancyrodella, Mesotaxis, Palmatolepis, Polygnathus, and Zieglerina are described. Two new species Ctenopolygnathus parallelus sp. nov. and Polygnathus masonae sp. nov. are distinguished and five species are described in the open nomenclature. Special chapter is devoted to the phylomorphogenesis of Ancyrodella.

A catalog of mosquito species (Culicidae family) from the Asian region of Russia

A new checklist of mosquitoes (Culicidae) recorded in the Asian part of Russia includes 79 species. The checklist is provided with taxonomic comments and compared with ones compiled by previous authors. In a comparison to the checklist of Kukharchuk (1980) including 73 species, 10 species are added into the present checklist and 6 species mentioned by this author are excluded, as far they were not actually found in Asian part of Russia. The names of 9 species are chanced according to the International Code of Zoological Nomenclature (1966). In the checklist of Stojanovich and Scott (1995) including 64 species, 5 species were included erraneously and 21 species were missed. The classification and valid species names are listed according to the Catalog of the Mosquitoes of the World (Knight, Stone, 1977) and its supplements (Knight, 1978; Ward, 1984, 1992; Gaffigan, Ward, 1985), except 5 species. These species (Aedes implicatus, Ae. esoensis, Ae. rossicus, Ae. albescens, Ae. subdiversus) are considered in the comments to the checklist.

Lamyctes inexpectatus sp. n., characterized by a distinctive shape of the female gonopods, is described from European Russia. The new species is compared with other species of the genus Lamyctes from Russia, and a key to these species is given. Types of the new species are deposited at the Zoological Institute, Russian Academy of Sciences, St. Petersburg.     

Two ant species (Hymenoptera,Formicidae) from the Northern Caucasus,new to the fauna of Russia

Two ant species, Leptothorax gredleri Mayr, 1855 previously known from Western and Eastern Europe and Solenopsis juliae (Arakelian, l991) formerly known from the Transcaucasia (Armenia), were found in the Northern Caucasus (the republics of Kabardino-Balkaria and Karachay-Cherkessia) for the first time; both the species are new to the fauna of Russia. The distribution, ecology, and morphological characters of the species are considered.     

Chalcids of the subfamily Pteromalinae (Hymenoptera,Pteromalidae) as parasitoids of the bark beetles (Coleoptera,Scolytidae) in the fauna of Russia and adjacent territories

Eighteen species of ten genera of bark beetle parasitoids were found in the fauna of Russia and adjacent countries. Sixteen species of the parasitoids are recorded as new to the faunas of Belarus, Ukraine, Azerbaijan, Kazakhstan, Tajikistan, Uzbekistan, Kyrgyzstan, and regions of Russia. An annotated list of nineteen species of pteromalids, with data on the material examined, geographic distribution, and hosts is given. New hosts are reported for five species of the bark beetle ectoparasitoids. An original key to eighteen species and ten genera of Pteromalidae parasitizing bark beetles is provided.     

Description and DNA barcoding of Tipula ( Pterelachisus) recondita sp. n. from the Palaearctic region (Diptera, Tipulidae)

Tipula (Pterelachisus) recondita Pilipenko & Salmela, sp. n. is described. The new species is collected from two localities: Finland, Kittilä (North boreal ecoregion) and Russia, Primorski kray (Zone of temperate broadleaf and mixed forests). Although variation in the structure of male hypopygium between the Finnish and Russian populations is observed, DNA barcode sequences differ only by three nucleotides (0.2 % K2P distance), supporting presence of one widespread species. K2P minimum distances between the new species and 17 other species of the subgenus range from 5.3 to 15.8 % (mean 8.8 %). The new species is forest-dwelling, known from an old-growth herb-rich forest (Finland) and Quercus mongolica forest (Russia). The new species is perhaps closest to Tipula (Pterelachisus) imitator Alexander and in lesser extent to Tipula (Pterelachisus) pauli Mannheims; the inner gonostylus of both species are illustrated.     

Bacillariophyta in mountainous water bodies of the Barguzin Ridge

The species composition of Bacillariophyta in mountain glacial lakes of the Barguzin Ridge (the Cis-Baikal Region) is studied for the first time. More than 200 taxa, including new ones for the flora of Russia (60), are found. The predominance of representatives of the class Pennatophyceae (92%) in the species composition is recorded. The problem of discovering Baikal endemics in high-mountain water bodies is considered.     

<Emphasis Type="Italic">Xanthorhoe dudkoi</Emphasis> sp. n., a new species of geometrid moths (Lepidoptera,Geometridae) from the high mountains of Southeastern Altai

The new species Xanthorhoe dudkoi is described. This species is distinguished by the structure of the valval costa, the presence of 5–7 spines at the base of the aedeagal vesica in the male, and by a large oval-trapezoid ostium and a massive, well-chitinized ductus bursae in the female. The new species is similar to Odontorhoe tauaria Staudinger, 1822 in the color and pattern of wings. The type material of the new species is deposited at the Institute of Animal Systematics and Ecology (Novosibirsk, Russia) and in the private collection of V.V. Ivonin (Novosibirsk, Russia).     

Devonian antiarchs (Pisces,Antiarchi) from central and Southern European Russia

Antiarchi (Pisces, Placodermi) from the Devonian of central and southern European Russia (Central Devonian Field) are studied. Antiarchs belong to three families, the Asterolepididae, Remigolepididae (suborder Asterolepidoidei), and Bothriolepididae (suborder Bothriolepidoidei). The diagnoses of the order, two suborders, three families, and five genera (two of which are new) are given. Sixteen species, including one new, are described; ten taxa are determined in open nomenclature. Morphological structures of representatives of these families are considered in detail. Classifications of antiarchs and their position in the system of the lower vertebrates are discussed. Devonian vertebrate localities of central and southern European Russia that have yielded antiarchs are listed. Each locality is characterized by its ichthyoassemblage.     

New Species of Oribatid Mites (Acari,Oribatida) from Sakhalin Island

Entomological Review - Two new oribatid mite species collected in the park zone of Yuzhno-Sakhalinsk (Sakhalin Island, Russia) are described. Xenillus similis sp. n. is a large pale brown mite with...     

Neogene Deep-sea Smelts (Argentiniformes: Microstomatidae) from the Far East Russia

Deep-sea smelts (Argentiniformes: Microstomatidae, Bathylaginae) from the Miocene of Far East Russia (Sakhalin and Urup islands) are described. The specimens described belong to four taxa, one of which is assigned to a new species of the genus Leuroglossus. Like Recent smoothtongues, the new species has thickened medial rays in the caudal fin. The small number of abdominal vertebrae makes the new species similar to the extant southern smoothtongue L. stilbius, which occurs along the eastern coasts of the Pacific Ocean. The new species differs from extant smoothtongues in the short snout, which is not longer than the orbit. Phylogenetic analysis of morphological features of the new species, using a matrix of characters of living deepsea smelts, shows that it occupies a basal position in the genus Leuroglossus. Three other extinct taxa cannot be reliably classified below the level of the subfamily Bathylaginae or tribe Bathylagini because of insufficient preservation of available specimens. The new records of deep-sea smelts in Far East Russia show that this fish subfamily was widespread and highly morphologically differentiated in the Neogene.
