Abstract

Phylogenetic relationships among the Palaearctic genera of the subfamily Simuliinae are analyzed based on the matrix of 100 morphological characters and 37 taxa, including 6 outgroups. Parsimonic analysis was resulted in 3 consensus trees (weighting based on CI, RI and RC indices) of slightly different topology, which show monophyly of the subfamily Simuliinae, tribes Stegopternini, Nevermanniini, Wilhelmiini and Simuliini, and a possible sister-group relationships between the latter two tribes. Tribe Ectemniini is apparently a paraphyletic formation. The analysis also supports transferring of the Stegopternini and Nevermanniini from Prosimuliinae to Simuliinae.

Abstract

The key to 37 Palaearctic species and 6 subspecies of the genus Stagetus Wollaston, 1861 is composed. New morphological characters for species differences were used

Abstract

The species Globicornis (Hadrotoma) ingelehmannae sp. n. from Baltic amber is described, illustrated and compared with all known amber species of Globicornis Latreille, 1829. New species differs by the shape of antennae and black setation on dorsal and ventral surfaces.

Abstract

The Terellia virens group includes eight species of uniformly greenish flies with white setulose abdomens and hyaline wings, variable in the characters of the male and female terminalia. Three new species are described and illustrated: Terellia freidbergi sp. n. from Middle and Near East, from flower heads of Centaurea behen L., T. ivannikovi V. Korneyev et Evstigneev, sp. n. from European Russia, Kazakhstan and Uzbekistan, breeding in flower heads of Ce. chartolepis Greuter, and T. whitei V. Korneyev et Mohamadzade, sp. n. reared from flower heads of Cousinia spp. in Kazakhstan, Kyrgyzstan, Turkmenistan and Iran. Illustrated diagnoses or redescriptions of other species and a key to the species of Terellia with hyaline wings and white setulose abdominal tergites are given.

Abstract

The article presents the most complete data on the distribution of ectoparasites in the boreal Palaearctics (gamasid mites of the genera Spinturnix, Macronyssus, and Steatonyssus, bat flies of the family Nycteribiidae, fleas of the family Ischnopsyllidae) and its preferences for the hosts. On the basis of these data as well as the data for the resettlement of bats in Eurasia 30 species of boreal bat ectoparasites combined into three faunal complexes (Transpalaearctic, European-Ural and Siberian-Far East) and two groups (European-Ural species, penetrating to the east and Siberian-Far East, penetrating to the west). The boundary between the European-Ural and Siberian-Far East faunal complexes is situated presumably along the Irtysh River. The resulting zoning provides a new look at the parasitocenosis of ectoparasites in the taiga zone of the Palaearctics.
