The Karyotypes of Earthworms of the Genus Aporrectodea (Oligochaeta,
Lumbricidae) of the Fauna of Ukraine. Kotsyuba I. Yu., Vlasenko R. P., Garbar
O. V. The karyotype analysis of earthworms of the genus Aporrectodea Oerley,
1885 in the fauna of Ukraine shows that most of them are diploid (A. caliginosa,
A. longa, A. georgii (2n = 36) and A. dubiosa (2n = 32)). The karyotype of the
latter is described for the first time. Under the standard for this genus chromosome
number x = 18, A. dubiosa has υ = 16, whereas the standard chromosome number for
this genus is 18. Two species of the genus, A. rosea and A. trapezoides, are polyploid
(x = 18). The new polyploid race (6n = 108) is discovered in A. trapezoides.
Key words: earthworms, Aporrectodea, karyotype, polyploidy.

family Euglesidae: Euglesa korniushini Frolov, sp. n., Euglesa lyudmilae Frolov,
sp. n., Euglesa shcherbinai, Frolov, sp. n. Ecological characteristics of new
species are provided.

The Morphology and Biology of the Trematode
Gigantobilharzia acotylea (Digenea, Schistosomatidae). Akramova F. D., Azimov
D. A., Shakarboev E. B. Morpho-biological traits of the trematode Gigantobilharzia
acotylea Odhner, 1910 at all stages of ontogeny are studied. Mollusks Physa fontinalis
and Anisus spirorbis widespread in the waterbodies of the Syrdarya River valley
were found to be intermediate hosts of this trematode under natural and experimental
conditions in Uzbekistan. Prevalence of infection of P. fontinalis and A. spirorbis
by Gigantobilharzia spp. parthenitae and cercariae reached 0.4 and 0.3%, respectively.
Experimentally, 100% of these mollusks were infected. The maturation of cercariae
in intermediate hosts ranged from 23 to 44 days depending on temperature. The
cercariae actively penetrated the skin of birds and reached maturity in 3035
days. A complex of traits of various developmental stages, particularly cercariae
necessary for the differentiation of the Gigantobilharzia spp. is suggested based
on of the analysis of morpho-biological peculiarities of these trematodes.
Key words: trematoda, Gigantobilharzia acotylea, life cycle, miracidium, cercariae,
parthenitae, schistosomula, definitive host, intermediate host.

Ontogenetic Development of Olfactory Organs
in Grass Shrimp Pandalus kessleri (Decapoda, Pandalidae). Blinovΰ N. K., Cherkashin
S. A. The olfactory organ in decapod crustaceans is represented by the outer
antennular flagellum with specialized sensilla called aesthetascs. Characteristic
structures of the lateral antennular flagellum with olfactory setae in larvae,
juveniles and adults of grass shrimp Pandalus kessleri Czerniavski, 1878 are described.
Key words: grass shrimp, olfactory organ, development, aesthetasc.

Characteristics of Sex and Age Composition
of Calidris alpine (Aves, Charadriiformes) Migrating Across Sivash. Chernichko
I. I. The paper shows features of distribution based on regular captures
and measurements since 1986 on two sites of Sivash (Central and Eastern), which
are different in their hydrological regime and composition of forage macrozoobenthos.
Shorter-billed males reliably prefer Central Sivash for storage of fat reserves
at the expense of feeding on larvae of chironomids and possibly the brine shrimp.
For longer-billed females it is more profitable to concentrate on Eastern Sivash,
where they prefer to feed on polychaete worms. On basis of size characteristics
of the captured birds and their time dynamics, the paper considers suggested terms
of passage of different subspecies and populations of the Dunlin across the Azov-Black
Sea coast of Ukraine. Also differences in age composition of migratory waders
on different sites of Sivash are shown compared to other water bodies of the near
Black Sea area.
Key words: waders (Dunlin), migration, sex and age composition, the Azov-Black
Sea coast of Ukraine.

Phenetic Analysis of Intraspecific Variability
in Sable, Martes zibellina (Mammalia, Carnivora), by Complex of Nonmetric Skull
Traits. Monakhov V., Ranyuk M. The series of nonmetric cranial characters
proposed for revealing the intraspecific differentiation in sable is considered.
Studied treats have 069% of variability however the main share of significant
differences provided by those with variability more than 20% were appeared. Our
tests confirm existence of intraspecific divergence between sable populations
(and age/sex intrapopulational groups) which were found by other morphologic characters
earlier. We propose to use that series of nonmetrical treats for diagnostic descriptions
and population structure probing.
Key words: sable, Martes zibellina, Russia, monitoring of populations, craniologic
nonmetric traits, population structure.

Morphological Characteristics of Male Genitalia
in Some Species of the Genus Eurytoma (Eurytomidae, Hymenoptera). Klymenko S.
I. Based on the analysis of morphological characteristics of related species
of the genus Eurytoma, several groups of cryptic species poorly distinguishing
by external morphology, but clearly confined to certain hosts are shown to have
morphological differences of male genitalia that are highly species-specific and
can be useful for identification of cryptic species of the genus Eurytoma (E.
rosae Nees, E. strigifrons Thomson, and E. jaceae Mayr species complexes).
Key words: Hymenoptera, Eurytomidae, Eurytoma, genitalia, phallobase.
