Review and taxonomic notes on the genus Derostenus (Hymenoptera,
Eulophidae). Gumovsky A. V. — The genus Derostenus Westwood, 1833, is reviewed.
7 species are recognized for the genus, 2 of them described for a first time.
These are: D. gemmeus Westwood (European), D. punctiscuta Thomson (European),
D. freemani Yoshimoto (Nearctic), D. persicus sp. n. (Iran), D. trjapitzini sp.
n. (described from the Russian Far-East), D. sulciscuta Hansson (Oriental, East
Palearctic) and D. japonicus Hansson (Japan). The list of apomorphies of the genus
Derostenus is supplemented by two characters: the anterior margin of each notaulus
marked off by a drop-shape fissure, and the lateral panel of pronotum with a protruding
flange. This flange is present as a stub-like process near the notaular fissure
in the representatives of the gemmeus group, but being present as a plica in the
sulciscuta group. Also, the representatives of the sulciscuta group have the dense
brush of setae just in front of the notaular fissure. D. gemmeus recorded for
a first time in Ukraine, D. sulciscuta recorded for a first time in the Russian
Far-East (Primorye) and Kuril Archipelago, D. freemani recorded for a first time
in Wisconsin state (USA). Table of characters distinguishing each species, is
given.
Key words: Hymenoptera, Eulophidae, Entedoninae, Derostenus, morphology, distribution,

Mordellid Beetles (Coleoptera, Mordellidae)
in the Fauna of Kazakhstan and Middle Asia. Communication 3. Odnosum V. K.
— Rare and little known species from Êazakhstan and Middle Asia of the genera
Mordellistenula Stschegoleva-Barovskaja, Uhligia Horak, Mordellochroa Emery, Mordellistenochroa
Horak, Dellamora Normand are studied. Key diagnostic characters of males (maxillar
palpus, wings and genitalia) are used for the descriptions. Morphological diagnoses,
identification keys, new data on variability and geographical distribution of
these species are given. Type material of Mediimorda curvipalpis (Stschegoleva-Barovskaja,
1930) comb. n. is redescribed.
Key words: Coleoptera, Mordellidae, Êazakhstan, Middle Asia, diagnostics characters,

Distribution of ticks (Ixodoidea, Parasitiformes)
— ectoparasites of bats (Chiroptera) in Ukraine. Bobkova O. O. — Two species
of ticks — Ixodes vespertilionis (Koch) and Argas vespertilionis (Latreille, 1802)
— was founded during the studying of ectoparasites on the territory of Ukraine.
In total it was registered 90 specimens of ticks. New localities of registration
of A. vespertilionis on territory of Ukraine are resulted. Conditions of a habitation
of hosts and their ectoparasites are discussed.
Key words: Argas vespertilionis, Ixodes vespertilionis, ectoparasites, bats, Ukraine.

Wild mammal fauna of the Kyiv city and its
vicinities, and trends in its urbanization. Zagorodniuk I. V. — Review of
species composition of wild mammals occurred in the territory of the Kyiv megapolis.
Urban fauna is the poor variant of the wild fauna of the Kyiv region, and it is
consist just 1/3 of total list of species known from this territory. Main part
of species composition in urban communities (totally 23 species) are formed by
bats (8 species) and muroid rodents (7 species).
Key words: mammals, urban fauna, megacity, Kyiv, Ukraine.

Ulrtastructural study of Microsporidium kosewiense
sp. n. (Microspora, Thelohaniidae) — a Microsporidian Parasite of Psectrotanipus
larvae (Diptera, Chironomidae). Ovcharenko M. Î., Wita I. — The new microsporidium
is described, based primarily on ultrastructural characteristics. The parasite
infects the fat body cells of Psectrotanipus sp. Plasmodia with diplokaryotic
nuclei produce elongated diplokaryotic merozoites, which mature into sporonts.
Meiosis occurs before the octosporous sporogony. Sporophorous vesicle appears
before meiosis and probably divides after separations of uninucleate sporonts,
having an individual envelopes. Episporontal space contains granular inclusions
transformed into tubules or crystals during the spore maturation. The live spores
are uninucleate, oval shaped, 3.2 ± 0.5(2.9–3.5) x 2.2 ± 0.4(1.9–2.7) mkm in size.
The exospore is five-layered, the anisofilar polar filament is coiled into 3–5
tutns. The polaroplast is composed of a narrow anterior and wide posterior lamellae.
The posterior vacuole contains spongious posterosome.
Key words: microspora, new species, Diptera, Psectrotanipus.

The morphological reason for the stenobionticity
of Clausiliidae (Gastropoda, Pulmonata). Baidashnikov À. À. — Relationships
between the whorl parameters (the inter-sutural interval, width, whorl overlap,
the outer surface and the surface overlapped by adjacent whorl, etc.) were analyzed
in species of Clausiliidae and several other pulmonate families with high shell.
The present analysis shows that the outer whorl surface increasing in the following
cases: by transformation of the upper part of the spire from convex to slightly
concave; by the change of the shell shape from low and wide to high and narrow;
by the developement of the inner whorl armature. The high shell with inner whorl
armature developing at the early stages of post-embryogenesis is characterised
by the larger outer surface, than similar shells with the inner armature of the
whorl present only at the late stages of post-embryogenesis, or reduced. The microclimate
fluctuations in mollusc habitats may affect more significantly the species with
larger shell surface. Thus, the shell of Clausiliidae that have relatively larger
outer surface is more adapted to the moving on the upright substrates but more
sensitive to the microclimate instability, in comparison with the representatives
of other families with high shell, but smaller outer surface. Transformation of
the upper part of the spire from conical to dome-shaped and reduction of the inner
armature are treated as adaptations of a higher shell for xerothermic habitats,
in addition to the albinic and subalbinic surface.
Key words: Ñlausiliidae, stenobiont, spindle-like shape of shell, the outer whorl
surface, the inner whorl armature.

Morphologic Aspect of phylogeny of Hesperornithidae
(Ornithurae, Aves). Bogdanovich I. À. — Skeletal features of Hesperornithidae
pelvis and pelvic limbs were studied in compare with that of waterfowl recent
species. Comparative and functional analysis show that Hesperornithidae do not
compose one whole monophyletic group with loons and grebes as confirmed before
but consist an independent phyletic branch.
Key words: skeletal morphology, hesperornithes, phylogeny.
