New and little known species of the dance-fly subgenus <Emphasis Type="Italic">Xanthempis</Emphasis> Bezzi,genus <Emphasis Type="Italic">Empis</Emphasis> L. (Diptera,Empididae), from the Caucasus

Five new species of the subgenus Xanthempis Bezzi are described from the Caucasus: Empis (Xanthempis) annae sp. n. (Russia: Krasnodar Territory), E. (X.) grichanovi sp. n. (Russia: Krasnodar Territory; Georgia), E. (X.) pseudoconcolor sp. n. (Russia: Krasnodar and Stavropol territories; Georgia: Abkhazia), E. (X.) teberdaensis sp. n. (Russia: Karachay-Cherkessia), and E. (X.) zamotajlovi sp. n. (Russia: Krasnodar Territory and Adygea). The females of E. (X.) alanica Shamshev and E. (X.) kovalevi Shamshev are described for the first time. New data on the distribution of some previously described species are reported. The geographical distribution of Xanthempis is discussed. A key to Xanthempis species from the Caucasus is compiled.     

Miocene ants (Hymenoptera,Formicidae) from Crimea

Ant imprints, new and previously known, from Middle Miocene deposits near Kerch (Crimean Peninsula, Russia) are described or redescribed. A new Myrmicinae species, Solenopsis atavinus sp. nov., is described based on a wingless female. A winged female similar to the earlier described Dolichoderus tauricus Dlussky, 1981 is found: due to the excellent preservation of this specimen, the new specimen and the holotype of D. tauricus are redescribed and can be reclassified as Ponerites tauricus (Dlussky, 1981), comb. nov. Oecophylla taurica sp. nov. is described based on a partly preserved imprint of a female thorax with a forewing, the venation of which allows it to be positively identified as a weaver ant. Two other species are transferred from the formal genus Camponotites to Oecophylla based on forewing venation: O. kraussei (Dlussky et Rasnitsyn, 1999), comb. nov. (Early Eocene, United States) and O. macroptera (Dlussky, 1981), comb. nov. (Middle Miocene, Stavropol, Russia). One of the studied forewing imprints is similar in venation to Paraphaenogaster microphthalmus Dlussky, 1981, described from the Middle Miocene of Vishnevaya Balka (Stavropol province, Russia) and so is attributed to this species. Dolichoderus tavridus sp. nov. is described based on a forewing.     

Five new species of <Emphasis Type="Italic">Conocybe</Emphasis> (Agaricomycetes,Bolbitiaceae) from Russia

Salicaceae-Feeding Leaf-Mining Insects in Siberia: Distribution,Trophic Specialization,and Pest Status

This paper provides an overview of the leaf-mining insect community feeding on willows (Salix spp.) and poplars (Populus spp.) in Siberia. According to published data and our own observations, 50 leaf-mining insect species (i.e., 24 species of Lepidoptera, 15 Coleoptera, 6 Diptera, and 5 Hymenoptera) feed on those two plant genera in Siberia. Using an integrative approach combining field work, morphological and DNA barcoding analyses, we identified 32 leaf-mining insect species from 14 regions across Siberia (i.e. 64% of all leaf-mining species known on Salicaceae in this part of Russia). Among them, 26 species most often found in parks and botanical gardens, represented new faunistic records for several poorly explored regions of Siberia. We have more than doubled the list of Salicaceae-feeding leaf-mining insects in Tomsk oblast, Altai krai, and the Republic of Tuva, and for the first time provided data on leaf-miners for the Khanty–Mansi Autonomous Okrug. The micromoth Phyllocnistis gracilistylella (Gracillariidae), recently described from Japan, was found on a new host plant (Salix caprea) in the south of Krasnoyarsk krai, is new for Russia. Eight leafmining insect species (i.e., five gracillariids: Phyllocnistis labyrinthella, Ph. unipunctella, Phyllonorycter apparella, Ph. sagitella, and Ph. populifoliella; two beetles: Zeugophora scutellaris and Isochnus sequensi; and one sawfly: Heterarthrus ochropoda) can outbreak on poplars, most often in urban plantations, botanical gardens, and plant nurseries in Siberia, and can also affect natural stands. Forty-five species of 50 leaf-mining insects known to feed on willow and poplar in Siberia also occur in Central and Eastern Europe. The remaining five species (Phyllocnistis gracilistylella, Phyllonorycter sibirica, Heterarthrus fasciatus, Tachyerges dauricus, and Isochnus arcticus) are recorded in Asia only. Species richness of the family Gracillariidae, the most diverse on Salicaceae in Siberia, displays 80% similarity to that in the European part of Russia and 71% to the Russian Far East. We discuss the faunal similarity of these regions and highlight the importance of applying an integrative approach combining ecological, morphological analyses, and DNA barcoding to explore and characterize the insect fauna of poorly studied regions of Asian part of Russia.     

Notes on the fauna and taxonomy of the click beetles (Coleoptera,Elateridae) of Russia and neighboring countries

New data on the distribution and taxonomy of some species of click-beetles in Russia and adjacent countries are given. Several species are recorded for the first time for the following territories: Brachygonus bouyoni (Chass.), B. dubius (Plat. et Cate) and Zorochros lewisi (Schw.), for Russia; Sericus sulcipennis (Baudi), for Ukraine; Berninelsonius hyperboreus (Gyll.), Cidnopus parallelus (Motsch.), and Limonius poneli Les. et Mertl., for Kazakhstan. New interesting findings of Sericus sulcipennis and Selatosomus songoricus (Kr.) are reported. Comments on some erroneous faunistic records of several elaterids, including some species from Middle Asia, are made. The following new synonymy is established: Haterumelater fulvago (Marseul, {dy1868}) = Elater tauricola Gurjeva, 1957, syn. n. Notes on the variability of Selatosomus latus (F.) are given, and its conspecificity with S. corpulentus (Cand.) is confirmed. The external morphology and genitalia of the little known Selatosomus nanus Gur. are studied, and the systematic position of this species is discussed.
