species of the Black Sea fishes. Belofastova I. P. — Records and own
materials on four species of the genus Acanthocephaloides, (A. propinquus (Dujardin,
1845) Meyer, 1933; A. incrassatus (Molin, 1858) Meyer, 1933; A. kostylewi Meyer,

species with 4–6 hooks in 10–12 longitudinal rows on the proboscis; it parasitizes
and parasites in 29 species of Black Sea fishes; A. kostylewi is a specific parasite
of Solea nasutus (Pallas, 1814) with 5–7 hooks in 12–16 longitudinal rows on the
proboscis and apparently is closely related to Solearhynchus soleae (Porta, 1905)

New species of the parasitic copepod Salmincola mica sp. n. (Lernaeopodidae) from the round whitefish Prosopium cylindraceum (Coregonidae), of the Anadyr River. Shed’ko M. B. — At inspection of the coregonid fishes from the Anadyr River (Chukchi Peninsula) two females (mature adult and young adult) of the new species Salmincola mica sp. n., were found on the tip of the gill filaments of round whitefish Prosopium cylindraceum. The diagnosis of S. mica sp. n.: second maxilla has a marked inflation around of the basis bulla, winh is clavate, long; length of maxilliped palp is less than 1/3 length of subchela (exclusive of claw); ventral process 4 of terminal segment of endopod of second antenna is as large as dorsal hook 1 and armed with relatively large spines, also it has another much smaller process 5; the ventral papilla of the first maxilla is reduced, exopod has short seta; the mandible has seven teeth, the proximal three being much smaller than the rest. The description of the found copepods is resulted.Key words: new species, Salmincola mica, copepoda, Coregonidae, Prosopium cylindraceum.

Intrapopulational differentiation of
the marsh frog Rana ridibunda (Amphibia, Anura) according to length and body proportions.
Peskov V. N., Kotserzhynska I. M. — Age and sex variations of body proportions
have been studied in population of the marsh (Rana ridibunda Pall., 1771) frog
from Kyiv sity. It has been shown, that males and females of Rana ridibunda clearly
differentiate into three groups: subadultus, adultus–I and adultus–II according
to body proportions. It has been established, that not only degree, but also a
character of sex differences changes with age according to body proportions.
Key word: marsh frog, body proportions, age changes, sex differences, morphogenesis.

Complex Analysis of Morphological Characters
of Gamasid Mite Varroa destructor (Parasitiformes, Varroidae). Akimov I. A., Benedyk
S. V., Zaloznaya L. M. — The study of seasonal variability of mite V.
destructor was carried out. The summer generation of mites appears to be characterized
by the largest morphological variability whereas the winter one has stable characters.
We failed to evolve the complex of morphological characters that would allow us
to identify, with high level of reliability, certain phenotype of the mite. Significant
stability of morphological characters of V. destructor in the course of time was
determined. The mean values of the length and width of the body allow to consider
the Ukrainian population of Varroa mite, which parasitize the honey bee Apis mellifera
Linnaeus, as the Korean haplotype of Varroa destructor Anderson et Trueman, 2000.
Key words: Varroa destructor, gamasid mites, morphology, seasonal variability.

Application of the diagnostical deworming
method to the horses intestinal helminths investigation. Kuzmina T. A., Kharchenko
V. A., Starovir A. S., Dvoinos G. M. — Commonly, the intestinal helminth
communities of horses are studied by the post mortem methods. The aim of our investigation
was to study the intestinal strongylid community of brood horses from three regions
of Ukraine after deworming using aversektin anthelmintic drugs. Twenty five strongylid
species were found in the horse examined. Every horse was parasitized by 7 to
20 strongylid species. The most prevalent species were Cylicocyclus nassatus and
Cyathostomum catinatum. They were found in 100% of horses examined and composed
respectively 36.5% and 17.5% of the total number of the strongylids collected.
Cylicocyclus leptostomus, Cylicocyclus ashworthi, Cylicostephanus calicatus, Cylicostephanus
longibursatus and Cylicostephanus minutus were found in 80% of horses examined
and composed in sum 36.1% of the total number of the strongylids collected. Besides
the Strongylida, the adult and larval stages of Parascaris equorum, Oxyuris equi
and the larvae of the gastric bots of the genus Gasterophilus were found in faecal
samples. The possibility of using the diagnostical deworming method to study the
species composition of horses was discussed.
Key words: Strongylida, horses, the diagnostical deworming method, helminths of

koreanus, P. muelleri, P. vespertilionis, Lecithodendrium linstowi, Prosthodendrium
ascidia, P. chilostomum, P. longiforme, Parabascus duboisi. Some morphological
and ecological characteristics of parasites are discussed. Differences between
tematodes fauna of sibling species were detected: M. brandtii infected by 9 trematode
species, but M. mystacinus infected just by 2 species — Plagiorchis koreanus e
Prosthodendrium ascidia.
Key words: Trematoda, Monorchiidae, Myotis brandtii, M. mystacinus, Samarskaya

The nematode (Nematoda) fauna of potato
tubers with ditylenchose. Zhilina T. N. — Species composition of nematodes
found in ditylenchose attacked potato tubers is analysed. These species belong
to three ecotrophic groups: phytohelminths (plant parasites), mycohelminths (mycotrophs)
and saprotrophs (saprobios feeders). Saprotrophs is the predominant group over
others species. Two species, Ditylenchus destructor Thorne, 1945 (phytohelminths)
and Mesodiplogaster lheritieri (Maupas, 1919) Goodey, 1963 (saprotrophs), have
in the number the dominating status in affected tubers of potato plant.

V. I. — Karyotype of «western» form of common spadefooted toad, the Pelobates
fuscus (Laurenti, 1768) from three region of Ukraine was investigated. 13 pairs

at the short shoulder of 7-th pair chromosomes. The sexual chromosomes are not
identified.
