436 kbAnts (Hymenoptera, Formicidae) from the Rovno Amber. Dlussky
G. M., Perkovsky E. E. — One hundred and eight specimens of ants from the
Eocene Rovno amber are studied, with 101 specimens being identified up to the
subfamily, 93 to the genus and 80 to the species level. Described as new are Dolichoderus
zherichini Dlussky sp. n., Tapinoma aberrans Dlussky sp. n., T. electrinum Dlussky
sp. n., Oligomyr-mex nitidus Dlussky sp. n., O. ucrainicus Dlussky sp. n. About
74% ant specimens belong to species also known in the Baltic amber. However, in
terms of relative species abundance the two assemblages are essentially different.
In the Rovno am-ber assemblage, about 26% of ant specimens are represented by
the new genera and new species. In contrast, new collections of Baltic amber of
similar size yield much less proportion (normally 2–5%) of specimens belonging
to new species. Also, about 70% of Rovno ant specimens belong to recent genera,
as opposed to about 52% in the Baltic amber. This indicates a geographically independent
origin of Rovno and Baltic amber, but not necessary their different age.
Key words: Hymenoptera, Formicidae, ants, new species, Rovno amber.

About Polyploidy and Aneuploidy in Cells of
the Family Unionidae (Mollusca, Bivalvia) in the Area of Ukraine. Melnychenko
R. K. — The polyploidy and other cytogenetic anomalies have been found in
cells of the tissues of gills and gonads in Unionidae from different river basins
of Ukraine. The possible causes of this phenomenon are discussed.
Key words: mollusks, Unionidae, karyotype, polyploidy, cytogenetic anomaly.

Rhynocoris persicus (Heteroptera, Reduviidae):
Three Species or One? Putshkov P. V. — The study of type-specimens and other
material demonstrates that Rhynoco-ris persicus (Jakovlev, 1877) = Rh. christophi
(Jakovlev, 1877), syn. n. = Rh. analis (Jakovlev, 1889), syn. n. The two latter,
as well as Rh. christophi f. pic-tipes (Horvath, 1911), are only melanistic forms
of the former. The type of colour variability in Rh. persicus is similar to those
in Rh. iracundus (Poda, 1761) and Rh. monticola (Oshanin, 1870). Key taxonomic
characters and geographic range of Rhynocoris persicus (Jakovlev, 1877) as well
as those of its infraspecific forms are reconsidered. The species inhabits not
only the vast regions of the Fore Asia, but is present in Kazakhstan too. Besides
other characters, its main differences from Rh. iracundus and other Rhynocoris
species are the details of the aedeagal theca structure for male and the spindle-like
incrassation of the hind tibia for female. The latter character as well as the
wax-like substance covering this tibia may be associated with some unknown feature
of the reproductive biology probably related to egg-deposition process.
Key words: Heteroptera, Reduviidae, Rhynocoris, variability, diagnostic, new synonyms,

Himalayan Myrmica Species (Hymenop-tera, Formicidae). Radchenko A. G., Elmes G.
W. — First descriptions of queens of seven of Myrmica ant species and males
of four of these species are given. The spe-cies were first described between
1865 and 1947 from workers. They form part of the distinctive Himalayan Myrmica
fauna that inhabit the south-western slopes of the Himalaya. Drawings, measurements
and indices of the specimens are provided and the key characters that distinguish
them from the other related Himalayan Myrmica spe-cies are noted.
Key words: ants, Formicidae, Myrmica, Himalaya, sexual forms, first descrip-tions.

Structure and Diversity of Benthic Community
During Succession. Mazlumian S. À., Prosvirov Yu. V. — Successional studies
were performed under experimental and natural conditions in coastal waters of
Western Crimea (Black Sea). The studies involved evaluation of the temporal diversity
dynamics, species richness and even-ness in experimental and bottom communities.
In the period of increasing density of meroplankton, species diversity was higher
in the experimental community. How-ever, at the same period, species richness
was higher in the bottom community. In the period of low density of meroplankton
the diversity of experimental and bottom communities were similar. The season
of colonization determined the equilibrium steady-state of experimental community.
Key words: bentos, structure of communities, log-normal plotting method, diver-sity

The Peculiarities of Crossing and Reproduction
of the Land Snail Xeropicta der-bentina (Pulmonata, Hygromiidae) at Northern Boundary
of its Range. Kramarenko S. S. — Mate choice of the land snail is found to
be is accidental in regard to the shell banding pattern, while in regard to the
shell size the choice is as-sortative. The fecundity of the X. derbentina varied
from 6 to 111 eggs per clutch with average value — 41.1 + 3.9, and the egg diameter
— 1.45–1.78 mm (the general mean is 1.61 + 0.02); it is suggested that neither
the fecundity nor the egg size depend on the shell banding pattern or the shell
size.

The Influence of Anthropogenic Barriers on
Phenotypical Structure of Populations of Cepaea hortensis (Gastropoda, Helicidae)
under Urban Conditions. Sverlova N. V. — The influence of various anthropogenic
barriers on frequency of banded shells in populations of C. hortensis (Muller,
1774) was studied. Mass occurrence of the species in Lviv area was connected with
peculiarities of planting of trees and shrubs in the city and with transfer of
mollusks by people.

Acartia tonsa (Copepoda, Calanoida): a New
Species in the Caspian and Azov Seas Zooplankton. Prusova I. Yu., Gubanova A.
D., Shadrin N. V., Kurashova E. K., Tinenkova D. Ch. — Acartia tonsa Dana
is found in zooplankton samples from the Cas-pian and Azov Seas. It is supposed
that earlier this species was misidentified in the Caspian Sea as Acartia clausi
Giesbrecht. Examined females and males of A. tonsa from the Caspian Sea are figured
and described and compared with A. clausi from the Black Sea.

Crab Pilumnus hirtellus (Decapoda, Xanthidae)
Distribution in Small Phyllophora Field in the Karkinitsky Bay of the Black Sea.
Terentyev A. S. — Spawning aggrega-tions of Pilumnus hirtellus (Linnaeus,
1758) was found in small Phyllophora field in the Karkinitsky Bay. It was determined
that aggregations of red algae phyllo-phora serve as a spawning area for this
crab species. The dependence was found be-tween their abundance and abundance
of Phyllophora biomass. Minimum of algae bio-mass necessary for successful spawning
is 2 g/m2. In spawning areas animals were located by groups of 3.3 ± 0.6 individuals
with the correlation of males and fe-males — 1 : 1.1. One third of all females
had eggs. Males constituted the most part of single animals. Average carapace
width of females joining groups was 6.1 ± 2.7 more than that of single ones. We
did not found this difference among males.
Key words: Pilumnus hirtellus, small Phyllophora field, spawning aggregation.

Wintering of the Black Kite (Milvus migrans)
in Ukraine. Tsvelykh A. N., Panjushkin V. E. — Since 1998 wintering of the
Black Kite is recorded in Ukraine in the Danube delta and the Southern Crimea.
In the Crimea this species was consid-ered a rare migrant and occasionally summering
species (dates of records are pre-sented). There are detailed data on appearance
and changes of the largest winter-ing gathering of the species in the district
of Sevastopol. Number of wintering birds increased every year and was 70 individuals
of a different sex and age in 2001. The features of feeding, rest and roost behavior
of the species are de-scribed, as well as interrelationships with other wintering
birds, namely Raven, Hooded Crow and Woodpigeon.
