The Intraspecific Variability of the Species of Genus Vestia (Gastropoda, Pulmonata, Clausiliidae) in Ukraine. Baidashnikov Ŕ. Ŕ. — Variability of the following indices in V. turgida (Rossmassler, 1836), V. gulo (Bielz, 1859) and V. elata (Rossma#ssler, 1836) is discussed: height and width of the shell, number of ribs per 1 mm in the penultimate and tip whorls, number of whorls in the shell, index of shell height/shell width. The influence of the presence or absence of rocks in the forests, or the biotopic factor, and the conditions of the forests in the area from Ukraine Carpathians to the Podolian Height, or the territorial factor, in the variability of these parameters is analyzed. The most variable species is V. turgida. V. gulo has the minimal variability. The degree of the intraspecific variability is explained by the interspecific difference of the shell structure and peculiarities of habitats. The biometric analysis confirms the subspecies rank of V. turgida procera. The shell structure in genus Vestia is suggested to explain the lowest values of the studied parameters (the whorl amount of the shell, the shell height/shell width ratio) than in sympatric representatives of other genera.
Key words: variability, shell parameters, Clausiliidae, Vestia, Ukraine.

The Genus Schizopera (Copepoda, Harpacticoida) in Uzbekistan (Central Asia). Mirabdullayev I. M., Ginatullina E. N. — Species of the genus Schizopera G. O. Sars, 1905 occurring in Uzbekistan are reviewed. Schizopera spinulosa Mirabdullayev et Ginatullina, sp. n. from Aydarkul Lake and Schizopera setulosa Mirabdullayev et Ginatullina, sp. n. from Ustyurt Plateau are described. In addition, S. jugurtha (Blanchard et Richard, 1891), S. reducta Borutsky, 1971 and S. aralensis Borutsky, 1971 have been previously recorded from Uzbekistan.
Key words: Copepoda, Harpacticoida, Schizopera, new species, Uzbekistan.

Review of Palaearctic Species of the Genus Iconella (Hymenoptera, Braconidae, Microgastrinae): Species with Propodeum Lacking the Median Longitudinal Carina. Kotenko A. G. — Twelve Palearctic species of the genus Iconella Mason, 1981 are considered; they share in having no median longitudinal carina on the propodeum. These species belong mostly to laspeyresiella group of the Apanteles sensu Nixon, 1965 in the sense of Papp (1982). Key to these species as well as the data on their distribution, type and other studied material, and their hosts (if known) are given. Iconella memorata Kotenko, sp. n., I. valiko Kotenko, sp. n. are described. Apanteles nephus Papp, 1974 and A. robustus Hedqvist, 1965 erroneously placed in the genus Iconella are removed for the Apanteles sensu Mason, 1981. Iconella britannica (Wilkinson, 1941) comb. n., I. erdoesi (Papp, 1973) comb. n. are transferred from the Apanteles sensu Achterberg, 2002.
Key words: Hymenoptera, Braconidae, Microgastrinae, Iconella, Apanteles, Palearctic Region.

Peculiarity of Ecology of Yellow-Legged Gull, Larus cachinnans (Laridae, Charadriiformes), during Nesting Period on Ukrainian Enclosed Inland Waters. Atamas’ N. S. — Nesting and feeding of Yellow-legged gull, Larus cachinnans Pallas, 1811, on the artificial reservoirs (fishing ponds) of Vinntsa and Lugansk Regions is considered. Feeding on artificial and on natural reservoirs (Svitjaz’ lake, Volyn Region) is compared. The distinction in main forage group ratio is shown. Namely fish was the main forage on the fishing pond, and rodents were ones on the lake. The primary cause of this was a low producing ability of explored natural reservoir in comparison with artificial ones, in which the sizeable number of the dead fish has arisen because of fishing management on such ponds. The principal limiting factor during the forming of colony for artificial reservoir was presence of the isolated site for nesting. At the same time on the lake there was a presence feeding resources enough. The three models of the forming of colony on the different reservoir depending on a presence of feeding resources were considered.
Key words: enclosed artificial reservoirs, Larus cachinnans, colony, feeding, limiting factors.

Morphological Peculiarities of the Hair Follicles of Ungulate Animals. Katsy G. D. — The morphological differences in the types of hair follicles (HF) in representatives of 18 genera are described. In the species that have predominance of the primary HF in the skin (cattle, horse et al.) the sweat secretion system is dominant, but in those that have polytypic HF (sheep, goat, deer et al.) — steroid system. The HF of the south species are situatied skin-deep, whereas they are deep in the species from temperat climate.
Key words: hair follicles, sweat glands, subcutaneous glands, types of skin.
Redescription of the Preimaginal Stages Protaetia (Eupotosia) affinis affinis (Coleoptera, Scarabaeoidea, Cetoniinae). Vasko B. N. — Illustrated descriptions of the 1-3-rd instar larvae and pupa of Protaetia (Eupotosia) affinis affinis (Andersch, 1797) are given. Original data on bionomics of this species are provided.
Key words: Scarabaeoidea, Eupotosia, morphology, biology, larvae, pupae.

Heterotrophic Flagellates of the Aeration Tanks in Sewage Treatment Construction from Zhitomir (Ukraine). Shevchuk S. Yu. — The data about finds of 12 heterotrophic species of flagellates in the activated sludge of the aerotanks in sewage treatment construction from Zhitomir are presented together with morphological features of found organisms and original pictures.
Key words: activated sludge, heterotrophic flagellates, Ukraine.
New Data on Distribution of Terrestrial Mollusks of the Subgenus Limacus (Gastropoda, Pulmonata, Limacidae) in Ukraine. Balashov I. A., Sverlova N. V. — New finds of molluscs of the subgenus Limacus Lehmann, 1864 made during 1998–2006 have been described in the territories of Odessa, Nikolaev, Herson, Zaporoje, Donetsk and Kyiv regions. These finds possibly show anthropochorous expansion of species distribution.
Key words: terrestrial mollusks, Limacidae, Limacus, anthropochory, Ukraine.

The New Eocene Ipelates (Coleoptera, Agyrtidae) from the Bitterfeldian Amber. Perkovsky E. E. — Second Late Eocene agyrtid species — Ipelates weitshati Perkovsky, sp. n. is described from the Bitterfeldian amber. It is strongly differs from the I. kerneggeri Perkovsky from Baltic amber by right hind angles of pronotum and longer antennae with narrower segments of the club (7th antennal segment 1.9 times as long as wide, 11th antennal segment 2.5 times as long as wide). It differs from the recent species of Ipelates with right hind angles of pronotum, I. striatipennis (Lewis) and I. castaneicolor (Champion), by the smaller size and sculpture of pronotum.
Key words: Coleoptera, Agyrtidae, Ipelates, taxonomy, Eocene, amber.

Distribution and Numbers of Great Grey Shrike, Lanius excubitor (Aves, Passeriformes), in Ukraine. Poluda A. M., Gavris G. G., Davydenko I. V. — Based on literature data and own observations, the number of the Great Grey Shrike breeding in Ukraine is shown to be extremely low during XX century, except the nineties. In that time, the breeding area of the species covered part of Western Ukraine, namely the Carpathians foothills in Lviv, Ivano-Frankivsk, Chernivtsi, Zakarpattya Regions, northern areas of Volyn and Rivne Regions as well as Zhytomyr region. Noticeable increase in number of birds breeding in the Polissia and considerable extending of breeding area were recorded in the late eighties. Nowadays the species breeds throughout the Ukrainian Polissia and in the Carpathians foothills. Birds breeding in the Carpathians and Volyn region belong to the subspecies L. excubitor homeyeri Cabanis. Intermediate form to nominative subspecies occur of Volyn and Zhytomyr Regions and possibly in Kyiv and Chernihiv Regions.
Key words: Great Grey Shrike, distribution, number, Ukraine.
