Analysis of Regional Peculiarities of Strongylid (Nematoda,
Strongylidae) Biodiversity in Domestic Horses in Ukraine. Kuzmina T. A.
— Analysis of regional peculiarities of species composition and structure of
strongylid communities in domestic horses from various parts of Ukraine is presented.
More than 86,000 strongylid specimens were collected using the diagnostic deworming
technique from 180 horses in 10 regions (Kyivska, Kyrovogradska, Poltavska,
Kharkivska, Sumska, Donetska, Ternopilska, Zakarpatska, Khersonska and AR Crimea)
and identified to the species level. Thirty-three strongylid species from 12
genera were found — 26 species in the subfamily Cyathostominae and seven — in
the subfamily Strongylinae. General structure of the strongylid community appeared
to be multimodal. The highest biodiversity of strongylids was found in horses
from Southern regions of Ukraine (29 species from 12 genera) and the lowest
in Eastern regions (15 species from six genera). However, no statistically significant
differences in species composition of strongylid communities in horses from
various regions of Ukraine were found (p > 0.05). Comparison of strongylid
biodiversity in domestic horses from Ukraine with that from others countries
revealed the highest similarity of the strongylid communities from Ukraine,
Czech Republic, and Poland; the lowest was in horses from South Africa and north-western
Europe (France and the UK). Our results showed that the peculiarities of horse-keeping
conditions influenced the biodiversity of the strongylid communities in domestic
horses much more than climatic conditions in various regions.
Key words: strongylida, Cyathostominae, strongylid community, domestic horses,

New Species of Aphids of the Family Lachnidae
(Homoptera, Aphidoidea) from Ukraine and Russia. Mamontova V. A. —
Three new species of lachnids are described. Cinara meridionalis Mamontova,
sp.. (from the Black Sea Biospheric Nature Reserve, Ukraine) is similar to C.
setosa (Borner, 1950), differing by body coloration, distinctive sclerotization
of the abdominal tergites VII and VIII, 10 additional setae on 4th segment of
rostrum (C. setosa with 6 setae), and also by relatively shorter 5th antennal
segment. Cinara stekolshchikovi Mamontova, sp. n. (Primorskiy Kray, Far East
Russia) is similar to C. watanabei Inouye, 1970, differing by having sclerites
only on abdominal tergites I and VIII and lacking wide sclerotized crossband
on abdominal tergite III and marginal sclerites on abdominal tergites II–III,
short setae on antenna, and also siphuncular cones half as wide as in C. watanabei.
Trama orobanches Mamontova, sp. n. (Dnipropetrovsk Region, Ukraine) is similar
to T. rara Mordvilko, 1908, differing from it and other species of the genus
by the presence of secondary rhinaria on the antennal segment 3 of the aptera,
shorter setae on body and its appendages and smaller eye. Types are deposited
in the collections of the Institute of Zoology, National Academy of Sciences
of Ukraine (Kyiv) and Zoological Institute of Russian Academy of Sciences (Saint
Petersburg).

Meiosis, Embryonic, and Larval Development
of Anadara inaequivalvis (Bivalvia, Arcidae) Taken from the Black Sea. Pirkova
A. V. — Development of Anadara inaequivalvis (Bruguiere, 1789) mussel,
a colonizer in the Black Sea, is studied. The ova 52.5 ± 1.67 micr.m were laid
at the stage of diakinesis of meiosis prophase, and fertilized at the stage
of metaphase I. The duration of meiosis stage, embryonic and larvae development
at 25 °Ñ is established, while scrutinizing a metaphase plate of 18 bivalents,
measures 2.3–11.2 micr.m. Microphotos of early veliger, the structure of shell
and lock are presented, larvae measurements are given, and the structure of
provinculum is described.

On Influence of Latitudinal Changes in
Summer Temperatures on the Late Eocene Aphids Germaraphis (Homoptera, Aphidoidea)
and on Their Symbiotic Relationships with Ants. Perkovsky E. E. — Buchnera
aphidicola is an obligate symbiont of Aphidoidea that suffers from overheating,
thus it is a good reason for their relatively small quantity in the regions
with hot summer. Rovno amber forest was situated 5° to the south from the Baltic
amber forest, and this increased the probability of the periodical summer overheating
of aphids and hence weakens the vital capacity of Buchnera and their hosts.
This results in multiple reduction of aphids quantity up to complete destruction
of aphids colonies with mutant Buchnera (for example, with mutation ibpA). This
weakened the mutualistic interconnections of dominant species of the Rovno amber
ants with certain aphids species, particularly with dominant species Germaraphis
dryoides (Germar et Berendt, 1856). Since occurrence of myrmecophile aphids,
especially the long-beaked aphids like Germaraphis, directly depends on intensity
of ants' efforts to take care of aphids, the above has lead to multiple decrease
of the share of Germaraphis and especially G. dryoides in Rovno amber fauna.
Key words: symbionts, mutualism, evolution, thermal tolerance, syninclusions,
Aphidinea, Buchnera, Formicidae, Eocene, amber, Ukraine, Russia.

Biometrics and Taxonomic Status of Myotis
blythii (Chiroptera, Vespertilionidae) from Crimea: Cranial Size and Shape.
I. Dzeverin, M. Ghazali. — Crimean Myotis blythii (Tomes, 1857) were
attributed by various researchers either to European subspecies, Myotis blythii
oxygnathus (Monticelli, 1885), or to the Middle East subspecies, M. b. omari
Thomas, 1906. The multivariate analysis of variation based on 29 craniometric
characters indicates that Crimean Myotis blythii are the specimens of M. b.
oxygnathus.

Bird Distribution in Biotopes of Open
Agricultural Lands in Breeding Season. Kuzmenko T. M. — Based on comparative
analysis of the vegetation structure in fields of different crops and taking
into account intensity of land cultivation and types of avifauna communities
formed in these fields, we identified five groups of fields in the Left-Bank
Polissya and Wood-and-Steppe zone of Ukraine. The greatest number of breeding
species and the most abundant species are in the first group (cereals, flax,
white mustard, and buckwheat). The largest total average density, the highest
average density of breeding species with nesting of two characteristic species
is typical for fields of the second group (rapeseed and peas). The smallest
proportion of breeding birds and the large dominant proportion were seen in
low crops and in dense closed crops (soybean, lupine), these values are slightly
higher than those in fields of beet and potatoes.
