96 kbNew and Little-Known Tephritidae (Diptera, Cyclorrhapha) from
Europe. Korneyev V. A. Two new species of the tribe Terelliini (Tephritinae)
are described. Terellia (Cerajocera) cyanoides Korneyev sp.n. from northeastern
Ukraine differs from other species of the subgenus by combination of banded wing,
unmodified pedicel, black-spotted katepisternum and small size; its larvae bore
stems of Jurinea sp. ex cyanoides aggr. on sand dunes in pine forests. Orellia
tragopogonis Korneyev et Dirlbek sp. n. from Spain fits near O. scorzonerae (Robineau-Desvoidy),
differing by fused apical and preapical wing crossbands, fore femur dorsally white
setose and by larger size; its larvae feed in flower heads of Tragopogon dubium.
14 species of Tephritidae are recorded for the first time from certain European
countries. Keys to species of Terellia subgenus Cerajocera and Orellia are provided.
Key words: Diptera, Tephritidae, Europe, new species, new records.

The change of the biological periods and phases
in the annual life cycle of the beavers (Castor fiber) in the Krasnoyarsk region.
Panov G. M. The changes of the biological periods and phases occurred in
the annual life cycle of the beavers (Castor fiber Linnaeus, 1758) acclimatised
in the Krasnoyarsk Region (Russia) are considered on the background of main climatic
characteristics in the Don River basin (the place of origin of beavers-acclimatisants)
and the area of acclimatisation. The study revealed partial or complete difference
in the timing of the biological periods and phases between the two compared beaver
populations as well as some consequences of these changes in the beavers from
Central Siberia. Conclusions are made regarding the causes of several unsuccessful
attempts of the beaver release in the Krasnoyarsk Region and some recommendations
concerning their further acclimatisation in the northern part of the region.
Key words: beaver, acclimatisation, climate, biological periods and phases, Krasnoyarsk
region.

Morphology of the Family Skrjabillanidae (Spirurida,
Camallanina). Sokolov S. G. Data on the morphology of the cephalic end,
caudal end and ovejector of Skrjabillanus tincae Schigin et Schigina, 1958, S.
scardinii Molnar, 1966, and Molnaria intestinalis (Dogiel et Bychowsky, 1934)
are provided. New data on the structure of cloak in these species are presented,
and the 2 groups teeth are recognized in skrjabillanid nematodes: the oesophageal
teeth and onchia. The validity of the genus Agrachanus Tichomirova, 1971 is discussed
and its synonymy with Skrjabillanus is accepted.

Morphometric variation in wood mice, Sylvaemus
(Muridae) from Ukraine fauna. Lashkova E. I. Intra- and inter-specific variation
in four Sylvaemus species of Ukraine fauna has been studied. 4 ex-ternal and 23
craniometric characters were measured for 1596 specimens. Diagnostic value of
some characters as well as multiple trends in character sets variation have been
analyzed. Principal compo-nents analysis shows that morphogenetic dependence between
general skull size and sizes of auditory capsules, incisive apertures, several
structures of rostrum, and some other characters, are of allometric nature and
are essentially similar in four closely related species in Ukraine.
Key words: Sylvaemus, variation, principal components analysis, Ukraine territory.

Seasonal and Age Dynamics of Cestode Fauna
of the Starling Sturnus vulgaris in Left-Bank Ukrainian Polissya. Greben
O. B. The results of studies on seasonal and age changes of cestode infestation
in Sturnus vulgaris (Linnaeus, 1758) during spring-autumn 1999 in Chernihiv Region
are presented. Seven cestode species were found. Monopylidium musculosum (Fuhrmann,
1896) Fuhrmann, 1899 and Variolepis farciminosa (Goeze, 1782) Spassky et Spasskaja,
1954 were registered most often. Infestation was found to be maximal in April
starlings. Then it decreased in nestling season and gradually increased before
autumn migration. Nestlings from the primary eggs were free from cestodes. Infection
occurred only in the secondary clutch nestlings directly before they left the
nest. Infestation of young birds by cestodes is increasing gradually up to flying
away for the winter.
Key words: Cestoda, Sturnus vulgaris, seasonal changes, age changes, Polesye,

First report of Steinernema bicornutum (Nematoda,
Rhabditida, Steinernematidae) from the North Caucasus. Ivanova E. S., Spiridonov
S. E. Steinernema bicornutum Tallosi, Peters & Ehlers, 1995 was isolated
by Galleria baiting from soil samples collected near Krasnodar (North Caucasus).
The differences were found between the type (Yugoslavian) population and Krasnodar
isolate in the average length of infective juveniles and spicules. All these differences
(except spicule length in the second generation males) are not statistically significant.
The RFLP analysis was able to distinguish nematodes from these two populations
of S. bicornutum only in the Cfo I profiles (one restriction site in the type
culture and two restriction sites in the Krasnodar isolate). The 715 bp long fragment
of ribosomal gene (ITS1 + 5.8S + ITS2) of the Krasnodar isolate of S. bicornutum
was sequenced and compared with similar sequence of the type strain. In accordance
with RFLP data, one additional Cfo I restriction site was found in the Krasnodar
S. bicornutum. Totally, the difference in 18 pairs of nucleotides per fragment
of 715 bp was found between Krasnodar and type cultures, including 17 substitutions
and one deletion (in type culture). Reported morphological and molecular differences
are considered as inter-populational ones, and described nematodes from Krasnodar
as another isolate of S. bicornutum.
Key words: entomopathogenic nematodes, Rhabditida, Steinernema, S. bicornutum,
new isolate, morphology, rDNA.

On the Systematic Position of the Marine Fish
Leech Heptacyclus albus (Hirudinea, Piscicolidae). Utevsky S. Yu. The systematic
position of the marine fish leech Heptacyclus albus Epstein et S. Utevsky, 1996
from the North Pacific is reconsidered. Such diagnostic features as small anterior
sucker, weak pigmentation and transparent body, as well as peculiarities of its
biology (attaching to the isthmus of the fishes of the genus Myoxocephalus), allow
to transfer this species to the genus Oceanobdella and consider O. microstoma
from the North Atlantic and adjacent regions of the Arctic as its closest relative.
Oceanobdella alba comb. n. and O. microstoma may be considered an example of speciation
by geographical isolation.
Key words: Heptacyclus albus, Heptacyclus virgatus, Oceanobdella alba, Hirudinea,
Piscicolidae, leeches.

The Growth and Longevity of Chamelea gallina
(Mollusca, Veneridae) in the Black Sea. Boltacheva N. A., Mazlumyan S. A.
Annual growth rings were found in the study of shell sections of Chamelea gallina
(Linnaeus, 1758), from which the age and the longevity of Chamelea gallina were
determined. Based on standard individuals, maximum age of molluscs was assessed
as 9 years. Results obtained are compared with those known for Mediterranean population
of the same species. It was also found that Chamelea gallina collected from different
localities of the same area have comparable maximum shell length but considerably
differ in the growth rate.
Key words: Mollusca, Veneridae, Chamelea gallina, Black Sea, growth, longevity,

Peculiarieties of natural and synantropical
acari of Wright Side and Central Forest-steppe of Ukraine. Kovalishina S. P.
On the territory of Central Woodland-Steppe of Ukraine, 37 species of Acariformes
ticks belonging to 26 genera of 3 families were found. Shift to the protein enriched
food was resulted in ontogenetic changes of Acariformes and gave rise to different
ecological forms. The complexes of synanthropic Acaroidea imitate the formation
of natural sites. The structure and the number of ticks depend on the conditions
of environment and is a plastic and dynamic system.
Key words: ticks, acaricomplex, natural, synanthropic, Central (Cis-Dnieper) Woodland-Steppe
