Contribution to the Microlepidoptera Fauna of the South of Krasnoyarsk Territory and the Republic of Khakassia

This paper provides a list of 125 species from 22 families of Microlepidoptera collected in the south of Krasnoyarsk Territory and in the Republic ofKhakassia, with 63 species (50%) and 2 families (Bucculatricidae and Elachistidae) recorded in the region for the first time, and 11 species from 6 families being new to Siberia: Cauchas fibulella, Nemophora fasciella, N. minimella (Adelidae), Phyllonorycter sorbicola, Phyllocnistis extrematrix (Gracillariidae), Cosmiotes freyerella, Elachista subocellea (Elachistidae), Caryocolum alsinella, Scrobipalpula diffluella (Gelechiidae), Agonopterix intersecta (Depressariidae), and Ypsolopha horridella (Ypsolophidae). Three species are new to science: Phyllonorycter sp. and Phyllocnistis verae (Gracillariidae) from the suburbs of Krasnoyarsk and Chrysoesthia sp. (Gelechiidae) from the Republic of Khakassia. Almost half of the faunistic findings belong to two families, Gelechiidae (34 species) and Gracillariidae (24 species). In the former family, the number of species distributed in Krasnoyarsk Territory and/or Khakassia was increased by 1.5 times based on our collection. Trophic specialization remains unknown only for 7 of the 125 species. Most (90%) of the remaining 118 species are phytophagous, the others are saprophagous; 53 species are known as leaf miners. Phytophagous species feed on plants of 36 families and 21 orders. The largest number of microlepidopteran species inhabit plants of the orders Rosales and Fagales (25 and 24 species, respectively). Twelve species are known as pests: Tineidae (4 species), Gracillariidae, Gelechiidae (2 species in each), Argyresthiidae, Choreutidae, Lyonetiidae, and Plutellidae (one species in each). Four pest species have expanded beyond the Palaearctic in the last century: Choreutis pariana (Choreutidae), Scrobipalpa atriplicella (Gelechiidae), Plutella xylostella (Plutellidae), and Niditinea fuscella (Tineidae).     

Contribution to the fauna of rove beetles of the subfamily Euasthetinae (Coleoptera,Staphylinidae) from Baikal Area and adjacent territories

A list of species of the staphylinid subfamily Euasthetinae from the Baikal Area and adjacent territories is given. Edaphus beszedesi Rtt. and Euasthetus mandschuricus Puthz are new records for Russia, Eu. superlatus Peyer., for Siberia, Eu. laeviusculus Mnnh., for the Baikal Area, and Eu. ruficapillus Lac., for western Siberia. [Records of Eu. bipunctatus and Eu. ruficapillus from “Kamenesch-Podolsk” in the original Russian text actually refer to the misspelled City of Kamenets-Podolskii in Western Ukraine and, thus, the records of these two species for Western Siberia are erroneous.—Ed.]     

Species divergence in <Emphasis Type="Italic">Iris</Emphasis> series <Emphasis Type="Italic">Lacteae</Emphasis> (Iridaceae) in Russia and adjacent countries based on chloroplast DNA sequence data

In Russia, the species of the genus Iris L., series Lacteae Doronkin, the taxonomic structure of which still remains controversial, are found in the south of Siberia and the Russian Far East, as well as in other regions of Asia. Sequence analysis of three chloroplast DNA regions (rps4, trnL–trnF, and trnS–trnG) shows that, in Russia and adjacent countries, there are two genetically and geographically isolated Lacteae species. I. oxypetala Bunge grows in the south of the Russian Far East, and I. lactea Pall. grows in Siberia, Mongolia, and Kazakhstan. Genetic differentiation between the populations of I. lactea is extremely low and statistically insignificant (the fixation index Φ_ST = 0.057, P > 0.05), pointing to the unity of the gene pool and the absence of other Lacteae species in this area.     

Diversity and distribution of leaf mining insects on birches (<Emphasis Type="Italic">Betula</Emphasis> spp.) in Siberia

The diversity and distribution of leaf mining insects developing on birches (Betula spp.) in Siberia were reviewed based on published records and our observations. Analysis of the literature revealed 52 species of leaf miners recorded as feeding on different Betula species in Siberia. Among them, three species were listed under different names and six species were erroneously recorded as birch consumers. Thus, the revised list of birch leaf miners contains 44 species. Five moth and four sawfly species are mentioned in the literature as pests of Betula. Four sawflies are known to be invasive in North America. Our collections comprised 25 species, including the micro-moth Stigmella continuella (Lepidoptera, Nepticulidae), a new species for Siberia found in Novosibirsk. Immature stages of 15 species were identified using DNA barcoding. Twenty species were recorded from several regions of Siberia for the first time. The dominant group is Lepidoptera (31 species), followed by Coleoptera (7), Hymenoptera (5), and Diptera (1). Two-thirds of all the known leaf miners develop exclusively on birches; the remaining species also colonize alders (Alnus, Betulaceae), some Rosaceae, Salicaceae, and Ulmaceae. In our observations, the majority of insects (96%) developed on B. pendula. About half of them were also observed on the East Asian birches B. dahurica, B. divaricata, B. costata, B. ermanii, and B. gmelinii; five species were found on the North American birches B. occidentalis and B. papyrifera. All the leaf mining species listed in our paper for Siberia also occur in Europe. The similarity between the miner faunas of these regions is discussed and it is warned about possible errors in diagnostics of the Siberian species using the keys and catalogues for the European fauna. The importance of DNA barcoding in the study of the local insect faunas of poorly explored regions is also emphasized.     

The Influence of Parasitoids (Hymenoptera,Eulophidae) on Survival of the Lime Leafminer <Emphasis Type="Italic">Phyllonorycter issikii</Emphasis> (Lepidoptera,Gracillariidae) in Udmurtia

The species structure of parasitoids (Hymenoptera, Eulophidae) of the invasive lime leafminer Phyllonorycter issikii (Kumata, 1963) (Lepidoptera, Gracillariidae) was reexamined ten years after the latest survey. The work was carried out in 2015 in three previously selected test plots within the city of Izhevsk. Extremely high survival rates (61.7 to 89%) of the leafminer were observed while the parasitoid complex had a negligible impact on its mortality (0.6 to 1.6%). A slight structural transformation of the parasitoid complex was noted, namely a decrease in the number of dominants and a change of the dominant species. In addition, the species structure of the parasitoids collected in 22 populated localities in Udmurtia was studied in 2016. Five new parasitoids of the lime leafminer were found: Pnigalio pectinicornis (Linnaeus, 1758), Sympiesis acalle Walker, 1848, Chrysocharis amanus Walker, 1839, Ch. pentheus Walker, 1839, and Ch. polyzo Walker, 1839. Two species of parasitoids of Ph. issikii were recognized as new to Udmurtia: Pnigalio agraules (Walker, 1839) and Pediobius saulius (Walker, 1839).     

New data on the distribution and host plants of weevils (Coleoptera,Curculionoidea: Apionidae,Curculionidae) in the south of Baikal Siberia and in Mongolia

Two weevil species, Rhinoncus autumnalis Korotyaev, 1980 and Orchestes medvedevi (Korotyaev, 1995), comb. n. (from Rhynchaenus), both described from Mongolia, are recorded from Russia (Buryatia) for the first time. A key to five Orchestes species associated with elms in Eastern Siberia, the Russian Far East, and Mongolia is provided. Aizobius sedi (Germar, 1818) is recorded for the first time from Eastern Siberia based on the recent findings in Buryatia and on older collections from Tuva where it is associated with Orostachys spinosa (L.) C.A. Mey. (Crassulaceae); it is also recorded for the first time from Kyrgyzstan and Mongolia. Magdalis (Aika) margaritae Barrios, 1984, native of Mongolia, Northern China and the south of the Russian Far East, is recorded from Buryatia. Lixus (Broconius) korotyaevi Ter-Minassian, 1989, formerly known in Russia only from southern Tuva, is recorded from Buryatia where it was collected on Suaeda ?prostrata Pallas, which is the first known host of this species. Rhamphus ?oxyacanthae (Marsham, 1802) is reported from Buryatia where it was collected from Cotoneaster melanocarpa, and from Mongolia.     

A new species,a new synonym,and new records of the hover-fly genus <Emphasis Type="Italic">Cheilosia</Emphasis> Meigen (Diptera,Syrphidae)

A new species, Cheilosia richterae sp. n., is described in the nominotypical subgenus, being most closely related there to Ch. annulifemur Stackelberg, 1930. Two species, Ch. sootryeni Nielsen, 1970 and Ch. rufimana (Becker, 1984), are recorded from Russia for the first time. Ch. kuznetzovae Skufjin, 1977 is recorded for the first time from the Urals and western Siberia. The subgenus Nephocheila Barkalov, 2002 is synonymized with Nephomyia Matsumura, 1916. Figures of the male and female heads and the male genitalia are given for all the species.     

New belemnites (Megateuthididae,Cylindroteuthididae) from the Bajocian and Bathonian of the Yuryung-Tumus Peninsula,northern Siberia,Russia and their palaeobiogeographic implications

New species of Paramegateuthis (Megateuthididae) and Cylindroteuthis (Cylindroteuthididae) are described from the Bajocian–Bathonian boundary interval of the Yuryung-Tumus Peninsula, northern Siberia, Russia. Additionally, Paramegateuthis subishmensis Stoyanova-Vergilova, 1983, first documented from the Sub-Mediterranean region, is described herein from the Arctic. We propose the presence of a temporary passage between the Boreal and Tethyan seas in the European part of Russia during the Early Bajocian Humphriesianum Chronozone as an explanation of the migration of P. subishmensis. New belemnite records from the Yuryung-Tumus section contribute to the palaeontological characteristics of the Arctic domain.     

New data on trophic relations between eulophid parasitic wasps (Hymenoptera,Eulophidae) and lepidopterans in Ul’yanovsk Province

Twenty seven species of the family Eulophidae were reared from 20 new lepidopteran hosts in Ul’yanovsk Province. Among newly revealed host-parasitoid associations, 27, 9, 3, and 3 are those with Phyllonorycter (Gracillariidae), Stigmella and single species of Ectoedemia (Nepticulidae), Yponomeuta (Yponomeutidae), and Tischeria (Tischeriidae), respectively. Ectoparasitoids prevailed among parasitoids of the genus Phyllonorycter, and endoparasitoids, among parasitoids of the genera Stigmella and Tischeria.     

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.     

Check-list of the Aphidiid-Wasp subfamily Trioxinae (Hymenoptera,Aphidiidae) from Russia and adjacent countries

A total of 64 species belonging to 10 genera of the subfamily Trioxinae (Hymenoptera, Aphidiidae) are recorded from the former USSR: Betuloxys Mackauer, 1960 (6), Binodoxys Mackauer, 1960 (11), Calaphidius Mackauer, 1961 (1), Falciconus Mackauer, 1959 (2), Harkeria Cameron, 1900 (1), Lipolexis, Förster, 1862 (1), Monoctonia Starý, 1962 (2), Monoctonus Haliday,1833 (6), Sergeyoxys Davidian, 2016 (1), and Trioxys Haliday, 1833 (33). Four species, Harkeria angustivalva (Starý, 1959), Monoctonia japonica Rakhshani et Tomanovic, 2015, Monoctonus mali van Achterberg, 1989, and Trioxys iziphia Mackauer, 1967 are recorded from Russia for the first time. The distribution of 20 species already known from Russia is clarified.     

Polymorphism of Y-chromosomal microsatellites in Russian population from Southern Federal district of the Russian Federation

Haplotype frequencies and allele distributions at 11 STR loci of the Y chromosome were evaluated in 180 unrelated individuals from Russian population of Southern Federal district of the Russian Federation (Rostov oblast, Krasnodar krai, and Stavropol krai). Among 153 Y-chromosomal haplotypes discovered, 62 were unique. In the sample of Russian population, the most frequent haplotype (frequency of 5.56%) was 16-11,14-13-30-25-11-11-13-14-11-10 (for the loci DYS19, DYS385a,b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, and DYS439, respectively). Despite the high diversity of Y-chromosomal haplotypes in the Russian populations from the south of Russia (the h value was 0.997, 0.995, and 0.994 in Rostov, Krasnodar, and Stavropol samples, respectively), analysis of molecular variance (AMOVA) showed the absence of differentiation between the populations (Φ_ST = 0.1%, P = 0.36). Comparative differentiation analysis performed for 13 Russian populations from the European part of Russia pointed to low among-population differentiation in Y-chromosomal lineages (Φ_ST = 0.52%, P = 0.03).     

Hidden diversity in the <Emphasis Type="Italic">Antrodia malicola</Emphasis> group (Polyporales,Basidiomycota)

Taxonomy of the Antrodia malicola group is revised based on DNA, morphological, ecological, and geographic data. This species complex is not related to Antrodia s. str. but constitutes its own lineage within the large Fomitopsis – Daedalea clade. The A. malicola group includes five species. Antrodia malicola s. str. is distributed in North America and East Asia, and a few records of this species are reported from Azores and Africa. Its European counterpart is A. kuzyana, comb. nova, with wider pores. Infraspecific variability of A. malicola and possible gene flow between it and A. kuzyana in East Asia are detected based on tef1 sequence data. Antrodia cyclopis, sp. nova, is described as a large-spored relative of A. malicola from New Guinea. Antrodia minuta is reported here from several European countries and Siberia, and its morphological characters and host preferences are discussed. Its close relative is A. tuvensis, sp. nova, from Central Siberia, an unusual member of the group with sparse, flexuous skeletal hyphae.     

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.     

A review of the genus <Emphasis Type="Italic">Deporaus</Emphasis> (Coleoptera,Rhynchitidae) from the Russian fauna: 1. Subgenera <Emphasis Type="Italic">Pseudapoderites</Emphasis> and <Emphasis Type="Italic">Japonodeporaus</Emphasis>

The genus Deporaus from the Russian fauna is revised. Four species (D. pacatus, D. azarovae, D. septentrionalis, and D. hartmanni) of the subgenera Pseudapoderites and Japonodeporaus are found. Keys to the subgenera and to the species of the subgenus Pseudapoderites are given. The genus Deporaus, subgenera Pseudapoderites and Japonodeporaus, and four species are redescribed. The distribution of these species in Russia is discussed.     

Fossil wood of <Emphasis Type="Italic">Betula erkovetskiensis</Emphasis> sp. nov. (Betulaceae) from the Miocene of the Erkovetskii Brown Coal Field,Amur Region,Russia

A new species, Betula erkovetskiensis Blokhina et O.V. Bondarenko (Betulaceae), from the deposits of the Sazanka Formation (upper Middle?Upper Miocene) of the Erkovetskii Brown Coal Field (Amur Region, Russia) is described based on anatomical features of fossil wood. The new species shows some wood anatomical characters of the extant birch subgenus Betula, B. davurica, B. nigra (section Dahuricae), and B. papyrifera (section Betula). Fossil wood of Betula is found in the Amur Region for the first time.     

Genetic polymorphism,haplotype distribution,and phylogeny of <Emphasis Type="Italic">Daphnia</Emphasis> (Cladocera: Anomopoda) species from the water bodies of russia as inferred from the 16S mtDNA gene sequencing

The data on the genetic polymorphism of the most widespread Daphnia species occupying different water bodies of Russia are presented. The phylogenetic relationships between the examined species were established, and the haplotype networks were constructed. A fragment of the 16S mitochondrial DNA gene was used as a genetic marker. The results of molecular phylogenetic analysis generally coincided with modern concepts in the systematics of the genus Daphnia. The representatives of the divergent mitochondrial lineages within the D. longispina, D. pulex, and D. magna complex remain poorly investigated morphologically. For D. dentifera, a new habitat on the territory of Russia, namely, the water bodies of the Lake Baikal basin, was identified. A conclusion was made that the 16S mtDNA gene could be successfully used in phylogeographic analysis of the genus Daphnia.     

On the ecology of some species of genus <Emphasis Type="Italic">Stuckenia</Emphasis> (Potamogetonaceae) in lakes of Zabaykalsky krai and the Republic of Buryatia

This paper clarifies the distribution and ecology of representatives of the genus Stuckenia (S. chakassiensis (Kaschina) Klinkova, S. pectinata (L.) Börner, S. macrocarpa (Dobroch.) Tzvelev, and S. vaginata (Turcz.) Holub) in brackish and saline lakes in eastern Russia. It is shown that S. chakassiensis grows in most Transbaikal lakes with a high salinity instead of S. pectinata, as was described earlier. Therefore, the range of this interesting and still insufficiently known taxon significantly extends to the east of Russia. Being very common in the mineralized waters of West Siberia, S. macrocarpa was not observed in Transbaikalia. In soda waters of Transbaikalia, S. chakassiensis forms thickets with a rather high productivity.
