Estimation of Divergence Rates for Upper Teeth
in Closely Related Species Myotis blythii and M. myotis (Chiroptera, Vespertilionidae).
Ghazali M. A., Dzeverin I. I. Greater and lesser mouse-eared bats (Myotis
blythii Tomes, 1857, M. myotis Borkhausen, 1797)are closely related species that
diverged about one million years ago. Size of the vestigial structures of the
toothrow (the third premolar and the third molar) and the proportion of the first
and second molar areas from the total area of the studied teeth have not practically
changed during that time. Other structures evolved with different rates. Using
the Lynchs method we prove that real rates of evolution are lesser than expected
for the traits which were formed under the influence of solely random factors
(mutations and random drift). Apparently, the stabilizing selection, was the principal
factor of the evolution of the two species was stabilizing selection.
Key words: Myotis blythii oxygnathus, Myotis myotis myotis, teeth, teeth area,
divergence, stabilizing selection.

Formation of the Orbito-Temporal Region of
Chondrocranium in Embryogenesis of the Sand Lizard, Lacerta agilis (Reptilia,
Squamata). Kovtun M. F., Yarygin A. N. Serial sections of 29 Lacerta agilis
Linnaeus, 1758 embryos on the successive developmental stages, stained with hematoxylin-eosin
or alcian blue-hematoxylin-eosin, were examined. It was found that trabecula cranii,
acrochordal cartilage and pilae metopticae are the initial components of the orbito-temporal
region of L. agilis scull. Taenia marginalis emerges first in embryogenesis and
then taenia medialis forms. Frontal parts of taenia marginalis, that are the split-type
structures, originate from planum supraseptale and their posterior parts originate
from pilae accessoriae. Fenestra septalis forms due to thinning of the medial
part of interorbital septum.
Key words: skull development, reptiles, orbito-temporal region, interorbital septum,
taenia marginalis, taenia medialis, planum supraseptale, pilae metopticae, pilae
accessoriae, pilae antoticae.

Ontogenetic Variability of Linear Size and
Body Proportions and Periodization of Postembryonic Maturity of the Sand Lizard
Lacerta agilis (Reptilia, Squamata). Maliuk A. Yu. Age variations by linear
size and body proportions have been studied in population of the sand lizard (Lacerta
agilis Linnaeus, 1758). It has been established, that not only linear body size
increases, but also body proportions have a lot of changes. It is shown that four
stages of maturity (juvenis, subadultus, adultus, adultus-senex) are well-defined
by linear size, body proportions and reproductive organs in postembryonic development
of this species.
Key words: Lacerta agilis, linear size, body proportions, ontogenetic variability,
stage of maturity.

Zoogeography of the Root Nematodes of the
Suborders Hoplolaimina and Criconematina from Far East of Russia. Volkova T. V.
Twenty nine species of the root nematodes are recorded from Sakhalin Region.
Cluster analyses shows that the Sakhalin nematode fauna is small similar with
other Far East Russian regions. The fauna of this region is characterized by the
predominance of Transpalearctic elements. Two species endemic to Sakhalin is known.
Key words: Hoplolaimina, Criconematina, zoogeography, Sakhalin Region.

Ecological Spectrums of Heterotrophic Flagellates
(Protista) in Water Bodies of Ukrainian Polissya Area. Shevchuk S. Yu., Dovgal
I. V. Dependence of 26 heterotrophic flagellate species development in central
part of Ukrainian Polissya area from operating pH and concentrations of dissolved
organic matter and oxygen in the waters is considered. Narrowing of existence
spectrums in certain types of water body characteristic for some species of heterotrophic
flagellates is stated; this peculiarity is strongly expressed in the bogs where
specific complex of hydrochemical conditions to have a place.
Key words: heterotrophic flagellates, Ukraine, ecological spectrums, tolerance.

New Information on the Hosts and Distribution
of the Marine Fish Leeches Trachelobdella lubrica and Pontobdella muricata (Clitellata,
Hirudinida). O#ktener A., Utevsky S. Yu. Fish leeches collected in the Aegean
Sea, the Sea of Marmara and the Black Sea were examined. Trachelobdella lubrica
(Grube, 1840) was recorded for the first time from the ballan wrasse Labrus bergylta
(Osteichthyes, Labridae), marine bream Diplodus vulgaris (Osteichthyes, Sparidae)
and the grouper Epinephelus aeneus (Osteichthyes, Serranidae) from aquiculture.
The leeches of this species were found in the Aegean Sea and the Sea of Marmara
on the body surface, in the mouth and gill cavities of their hosts. Leeches identified
as Pontobdella muricata (Linnaeus, 1758) were collected from the thornback ray
Raja clavata (Chondrichthyes, Rajidae) in the Black Sea.
Key words: Aegean Sea, Sea of Marmara, Black Sea, Annelida, Clitellata, Hirudinida,
Piscicolidae, parasites.

The First Nest Records of the Wasp Eumenes
punctaticlypeus kostylevi (Hymenoptera, Vespidae, Eumeninae) and Notes on its
Distribution in Crimea. Fateryga A. V., Matushkina N. A. Two nest records
of the rare solitary wasp Eumenes punctaticlypeus kostylevi Kurzenko, 1976 are
described for the first time. One non-completed nest was built in a stone surface
and another one was attached to a bush stem; the latter one consisted of six cells.
Nest cells are arranged in a cluster and have common internal walls. All cells
are spirally disposed around the stem and theirs collars look at different directions.
A male was reared in the first cell and three females in the second to fourth
cells. Examination of the collection materials revealed that the distribution
area of the species in Crimea embraces zones of Foothills and South Coast.
Key words: Eumenes, Vespidae, Eumeninae, nesting, Crimea.
