Genus <Emphasis Type="Italic">Chelonus</Emphasis> Jurine (Hymenoptera,Braconidae, Cheloninae) in the fauna of Russia and adjacent territories. <Emphasis Type="Italic">Ch. olgae</Emphasis> Kok. species-group

The Ch. olgae species-group is established in the genus Chelonus characterized by the metasomal carapace narrowing towards the apex (much more strongly than towards the base) and not or weakly incurved. This group is analogous to the M. retusus group of the closely related genus Microchelonus, although some differences in the carapace structure emphasize parallel development of these morphological features in the two genera. New species are described as follows: Ch. borisi sp. n. (Russia: Leningrad Prov.), Ch. cardui sp. n. (Russia: Voronezh Prov.; Moldova), Ch. kokoujevi sp. n. (Russia: Belgorod and Chelyabinsk provinces), Ch. speijeri sp. n. (Spain), Ch. ubsunuricus sp. n. (Russia: Tuva), and Ch. yurii sp. n. (Kazakhstan). Chelonus subannulatus Abdinbekova, 1971 is synonymised with Ch. submuticus Wesmael, 1835(syn. n.).

The distribution of the Eastern Asian species of this genus in Russia is analyzed in detail. The data on their phenology, trophic associations, and habitat preferences are considered.     

The subspecies of <Emphasis Type="Italic">Chrysolina limbata</Emphasis> (Coleoptera,Chrysomelidae)

Examination of 1492 specimens of Ch. limbata (Fabricius, 1775) from the entire distribution range resulted in the discrimination of six subspecies: limbata (West Europe excluding the Apennine Peninsula, the Crimea, north and south of European Russia, the Great Caucasus, Northern Kazakhstan, and southern West Siberia), discipennis (Ménétriés, 1848) (southeast of European Russia, Western Kazakhstan), hochhuthii (Suffrian, 1851) (south of East Siberia, Eastern Kazakhstan, Mongolia, Northern China), luigionii (Depoli, 1936) (the Apennines, the Alps, Herzegovina, the Mediterranean coast of France); russiella ssp. n. (deciduous forests, forest-steppe and steppe of European Russia and Ukraine); volodi ssp. n. (alpine regions of the Lesser Caucasus and eastern Turkey). Ch. limbata findelii (Suffrian, 1851) is a new junior synonym of Ch. limbata limbata.     

Ecological features and distribution of the mosquito <Emphasis Type="Italic">Aedes communis</Emphasis> (De Geer, 1776) in the Northwestern European Russia

Distribution and biotopic and seasonal associations of the mosquito Aedes communis in Northwestern European Russia is discussed.     

A new species of the genus <Emphasis Type="Italic">Siteroptes</Emphasis> (Acari,Heterostigmata, Pygmephoridae) from European Russia

A new species, Siteroptes longisetissimus Khaustov et Ermilov sp. n., is described from European Russia (Nizhnii Novgorod Province).

Colasposoma dauricum (Mannerheim, 1849) is recorded for the first time from Altaiskii Territory of Russia and Southeastern Kazakhstan. A review of the distribution of this species with a dotted map is given.     

New Data on the Distribution of the Flea-Weevil <Emphasis Type="Italic">Orchestes steppensis</Emphasis> Kor. (Coleoptera,Curculionidae: Rhamphini) in European Russia

An elm flea-weevil Orchestes steppensis Korotyaev, 2016 was found on Ulmus pumila L. in the southeastern corner of Voronezh Province; formerly the westernmost records of this species in European Russia were those in Saratov Province and at the western boundary of Stavropol Territory. New data on the distribution of this and allied species in European Russia are reported.     

A new genus for <Emphasis Type="Italic">Hysteropterum boreale</Emphasis> Melichar, 1902 (Hemiptera,Auchenorrhyncha: Fulgoroidea: Issidae) from China

A new genus is erected for Hysteropterum boreale Melichar, 1902 which is redescribed. Lectotype is designated in the type series of the species deposited in the Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia).

On the knowledge of the geographic variation of the satyrid <Emphasis Type="Italic">Oeneis jutta</Emphasis> (Hübner, [1806]) (Lepidoptera,Satyridae) in the Northeast of European Russia

Analysis of the geographic variation of external characters of the satyrid Oeneis jutta (Lepidoptera, Satyridae) in the northeast of European Russia was carried out. Variation of the forewing length, diameter of eyespots, their total number and frequency of occurrence on the upper side of wings were studied. The regional populations of Oe. jutta were shown to lack significant differences in the characters studied. Besides the similarity of external characters, similar ecological traits also suggest that Oe. jutta populations from the northeast of European Russia belong to the nominative subspecies. The probable history of distribution of Oe. jutta across Europe also suggests that the nominative subspecies occurs in the territory studied.     

Contribution to the study of the northern limits of the range of <Emphasis Type="Italic">Apocyclops dengizicus</Emphasis> (Lepeschkin, 1900) (Copepoda,Cyclopoida)

The copepod Apocyclops dengizicus (Lepeschkin, 1900), a denizen of the saline waterbodies of the desert and semidesert regions of the world, was found in one of the tributaries of the hyperhaline Lake Elton (Volgograd oblast). This finding marks the northernmost locality where this species has been recorded in Russia. An analysis of the latest published data shows that the northern limit of the range of this species crosses the Russian Transvolga Region and middle Kazakhstan approximately along the 50th latitude. The northernmost locality where this copepod has been recorded to date is still its type locality, Lake Siletiteniz (53°N) in northern Kazakhstan. The possibility of finding A. dengizicus in adjacent oblasts of Russia as far north as the 55th latitude, where there are many highly mineralized waterbodies fit for this species, cannot be excluded.     

<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).
