In addition to a previously published study about Siberian Colletes species, we here further report on poorly known species. Twenty six species are currently known from Siberia with C. cinerascens Morawitz 1893, C. kaszabi Kuhlmann 2002, and C. ebmeri Kuhlmann 2002 found in Russia for the first time and C. wacki Kuhlmann 2002 is newly recorded from the Asian part of Russia. The male of C. wacki is here described for the first time and a lectotype designated for the closely related C. conradti Noskiewicz 1936 to clarify the taxonomy of this group. Colletes uralensis Noskiewicz 1936 was erroneously recorded from Russia and is removed from the list of Russian species. Images and updated distribution maps are provided for the closely related C. kaszabi and C. uralensis as well as for C. conradti and C. wacki to facilitate their identification. An updated checklist of the 42 species of Colletes so far known from Russia is provided.
As a supplement to a previously published study on Siberian Hylaeus species, we here report further records of twenty six rarely collected and little known species. Thirty two species are currently known from Siberia, including Hylaeus dorni Dathe, 1986, H. gredleri Förster, 1871, H. hungaricus (Alfken, 1905), H. moricei (Friese, 1898), H. nimbatus Dathe, 1986, H. oehlkei Dathe, 2010 and H. stubbei Dathe, 1986, which are reported from Russia for the first time, and H. brevicornis Nylander, 1852, H. communis Nylander, 1852, H. pfankuchi (Alfken, 1919) and H. styriacus Förster, 1871, which are newly recorded from Siberia. Hylaeus (Hylaeus) pesenkoi Proshchalykin & Dathe, sp. nov. is described as new from Siberia (Altai Republic and Tyva Republic) and neighbouring Mongolia (Khovd and Govi-Altai Aimags). The females of H. dorni Dathe, 1986 and H. oehlkei Dathe, 2010 are described for the first time; H. peregrinus Dathe, 1986 was recognised as the female of H. stubbei Dathe, 1986 and is treated as a new synonym.
All stages and the ecology of the Southern Palaearctic Palpomyia schmidti collected from the vicinity of the saline Lake Elton in Russia are described and illustrated. The morphology of larvae and pupae as well as the detailed ecology of the larvae are described for the first time. P. schmidti is a halobiontic biting midge, widely distributed in the steppes and deserts of the Palaearctic region. It is proposed that the Palpomyia schmidti group should include five Holarctic species. P. downesi Grogan & Wirth, 1979 from north-western North America is recognized as a new junior synonym of the Eastern Palaearctic P. tuvae Remm, 1972. New synonymy.
Twenty-nine species of mites of the family Laelapidae s. str. have been recorded as associated with small mammals (rodents, insectivores) in Asiatic Russia (Siberia and the Russian Far East). These species belong to two subfamilies (Laelapinae, Myonyssinae) and six genera: Androlaelaps Berlese, 1903, Dipolaelaps Zemskaya & Piontkovskaya, 1960, Laelaps C.L. Koch, 1836, Hyperlaelaps Zakhvatkin, 1948, Myonyssus Tiraboschi, 1904, Oryctolaelaps Lange, 1955. A list of the species, with data on synonymy, geographic ranges, and relationships with mammal hosts is provided. Some considerations concerning patterns of distribution of the parasitic Laelaptidae of Asiatic Russia are presented as well as their classifications from the point of view of known host association records.
Records of leafroller moths (Tortricidae) from the Rostov-on-Don province of southern Russia are presented based on 10 years of field work (2005-2014). The list includes 91 species from 43 collecting sites; 80 species are recorded from the region for the first time. Compared to other well-surveyed, adjacent areas, the tortricid fauna is considerably more depauperate, and this may be explained in part by the predominance of steppe vegetation.
Material from Spitsbergen (Norway) collected by Spitzenberger (1996) was reinvestigated. A new genus Arctocypris and a new species Arctocypris. fuhrmanni n. gen. n. sp. are described in the present paper. A key to the genera of the subfamily Eucypridinae is provided. At the moment Arctocypris n. gen. comprises four species: Arctocypris arctica (Olofsson, 1918) comb. nov.; A. dulcifons (Diebel & Pietrzeniuk, 1969) comb. nov.; A. foveata (Delorme, 1968) comb. nov. and Arctocypris fuhrmanni n. gen., n. sp.
A new springtail species of the family Arrhopalitidae, Arrhopalites potapovi sp. nov., is described. It belongs to the caecus species group characterized by 3,2,1,1,1 anterior setae on dens and separates from Arrhopalites caecus (Tullberg) and other congeners by strongly differentiated cuticular spines on sixth abdominal segment, shape of female subanal appendages and foot complex. It was found under the loose bark of trees from two localities along Lake Baikal and it is the second representative of the genus Arrhopalites Börner sensu stricto in Russia.
For the European part of Russia 30 species of the bee genus Colletes are recorded. Colletes subnitens Noskiewicz 1936, C. wacki Kuhlmann 2002 and C. warnckei Kuhlmann 2002 were found in Russia for the first time and C. kozlovi Friese 1913 is newly recorded from the European part of Russia. For Colletes kozlovi, C. subnitens and C. wacki this is the first record for Europe. The female of C. subnitens Noskiewicz is here described for the first time. Illustrated keys to males and females of all species known from European part of Russia are provided.
In Russia and the adjacent territories, the genus Hephathus includes three species, H. nanus (Herrich-Schäffer, 1835), H. freyi (Fieber, 1868) = H. tshakaranus Dlabola, 1957, syn. n., and H. achilleae Mityaev, 1967. They are indistinguishable in genitalia shape, but differ in male calling signal structure and black pattern of face. Photos of habitus and face, drawings of genitalia and male 2(nd) abdominal apodemes, signal oscillograms, and distribution maps for all species are provided. H. orientalis Linnavuori, 1953 is indistinguishable from H. freyi in coloration and genitalia shape; therefore, investigation of male calling signals is necessary for elucidation of its status. Macropsis fergusoni Evans, 1942 from Tasmania and Asmaropsis troilos Linnavuori, 1978 from Eritrea differ from Palaearctic Hephathus in the shape of head, pro-, and mesonotum and apparently belong to other genera.
