Tetrix tuerki (Orthoptera, Tetrigidae): Distribution
in Ukraine, Ecological Characteristic and Features of Biology. Pushkar T. I.
— The presence of Tetrix tuerki (Krauss, 1876) in the Ukrainian Carpathian Mountains
and Transcarpathian Region nowadays is confirmed. Three different morphological
forms of T. tuerki are distinguished based on the wings and prothorax lengths:
brachypterous, mesopterous and macropterous forms. Only two forms of adults (mesopterous
and brachypterous) and the larvae of middle and the last instars hibernate. Adults
of macropterous individuals of T. tuerki appear in June, developing from the hibernated
larvae. Some larvae of T. tuerki are emerged from eggs and become the adults at
the same year, transforming mesopterous and brachypterous forms. In spring T.
tuerki (brachypterous and mesopterous individuals) lives on sandy-pebble alluvion
of mountain river coasts, but in summer it (macropterous individuals) prefers
alluvions near the middle part of the river far from its coasts. All three morpho¬logical
forms of T. tuerki inhabit the middle flows of mountain rivers and the foothills
outside a mountain system; brachypterous and mesopterous individuals are widespread
in the upper reaches and in the lower flows of mountain rivers where alluvions
are rare. Body length of specimens of T. tuerki, inhabiting upper and lower flows
mountain rivers are smaller then in other river sides. Vibratory signals of T.
tuerki are described for the first time and the oscillograms of the vibratory
signals are provided.
Key words: Orthoptera, Tetrigidae, Tetrix tuerki, distribution, Ukrainian Carpathian
Mountains, alluvion of mountain rivers banks, phenology, vibratory signals.

Formation of Pattern and Diagnostic Instar
Features of the Head in Caterpillars from Genus Peridea (Lepidoptera, Notodontidae).
Dolinskaya I. V. — Pattern and colouration of caterpillar head of all larval
instar of 7 species from genus Peridea Stephens, 1828 are studied. Formation of
caterpillar head pattern in ontogenesis is discussed. Diagnostic characters, both
specific and larval instars, are recorded for the first time. Key to species according
to larval instars is given. Evidently, only larvae of the 1st instar demonstrate
different directions in the pattern formation. This characteristic can be used
for clearing of taxonomic relations in the genera and on the earliest ontogenetic
stages (1st larval instar) only. In the following (2nd–5th) instars, the pattern
became more or less of the same type. It depends on stripes shape or colouration
only and can serve as good specific diagnostic character. To determine larval
instar, both width of the head capsule and head pattern should be taken into account.
Key words: Notodontidae, Peridea, caterpillars, morphology, instars, head pattern,
diagnostic characters.

Morphological Variability and Differentiation
of the Goldfish, Carassius auratus, and Prussian Carp C. gibelio, (Cypriniformes,
Cyprinidae) in Reservoirs of Ukraine. Mezhzherin S. V., Kokodiy S. V. — Morphological
variability and differentiation bisexual Carassius auratus Linnaeus, 1758, three
clones unisexual C. gibelio Bloch, 1782 and hybrids C. auratus õ Ñ. gibelio on
20 plastic and 6 meristic characters are analyzed. It is established, that the
factor of a specific accessory renders extremely authentic influence on variability
of the most characters. Despite it, at paired comparisons all without exception
characters essentially transgress, that does not allow to use them in practical
diagnostics. Application of a complex of all characters gives an average level
of discrimination of 5 forms at a level of 86%. It is shown, that clones C. gibelio
are differentiated, first of all, on indexes of a body, and individual C. auratus
in the greater degree differs from C. gibelio s. l in number of elements in meristic
structures. Reliable differentiation of individuals of bisexual and unisex crucians
or identification of clones of the last is shown to be really feasible only on
gene markers in a combination with cytometric parameters. At the same time, use
of morphological characters is possible in some cases for homogeneous settlements
on series large enough and with taking into account sexual structure of a population.
Key words: Carassius auratus, Ñarassius gibelio, gynogenesis, clones, morphological
variation.

Peculiarities of the Intra- and Inter-Population
Structure of the Land Snail’s Brephulopsis Cylindrica (Gastropoda, Pulmonata,
Buliminidae) Conchiometry Variability. Kramarenko S. S. — The substantial
values of the intra-population variation conchiometry traits in the land snail’s
Brephulopsis cylindrica, Menke, 1828 are estimated. Generally, the intra-population
shell size and shape variation components are nearly 1/5 from sum of the intra-
and inter-population variability. Thus, peculiar spatial arrangement occurs for
the conchiometry variability within continuos populations (metapopulations) of
the land snail B. cylindrica, and a clinal pattern of the variation prevails.
The “conchiometry area effect” is detected in same cases, when a presence of the
intra-population subdivision of the shell size and shape occurs under absence
of the apparent spatial heterogeneity and “isolation-by-distance” model cannot
be received because of low dispersal ability of the land snail B. cylindrica.
Key words: land snail, Brephulopsis cylindrica, population spatial arrangement,
spatial autocorrelation, conchiometry “area effect”, North-Western Black Sea Coast,
Ukraine.

The Variety of Species and Peculiarities of
Distribution of Tetranychoid Mites (Trombidi-formes, Tetranychoidea) in Green
Plantings of Kyiv City. Zhovnerchuk O. V. — The 28 species of 10 genera of
tetranychoid mites are found on 101 plant species in Kyiv. The distribution of
tetranychoid mite species in various types of city plantings is analyzed. The
greatest variety of species is noted for botanical gardens. Schizotetranychus
tiliarium Hertmann, 1804 and Amphitetranychus viennensis Zacher, 1920 are found
to be the most noxious pests of plants in Kyiv. The cases of coexistence of different
species of tetranychoid mites on the same plant are noted.
Key words: tetranychoid mites, city green plantings, distribution of species,
