A Review of Predaceous Mites of the Genus Typhloctonus (Parasitiformes,
Phytoseiidae) in Ukraine with the Description of an Unknown Male of T. tuberculatus.
Kolodochka L. A. — Predaceous mites of the genus Typhloctonus Muma, 1961 from
different plants in Ukraine are reviewed. Four species of the genus Typhloctonus
are occurring in Ukraine: T. tiliarum (Oudemans, 1930), T. aceri (Collier, 1957),
T. runiacus Kolodochka, 1980 and T. tuberculatus (Wainstein, 1958) described,
illustrated, measured and keyed (on females). These species differ not only by
the features earlier indicated but by some additional characters revealed in this
study. Type material of Typhlodromus tuberculatus Wainstein, 1958 have been revised
and lectotype designated. Unknown male of T. tuberculatus is described, measured
and illustrated. Study of the holotype Seiulus (Typhloctonus) arutunjani Kuznetsov,
1984 shows it to be a junior synonym of the Typhloctonus tuberculatus (Wainstein,
1958).
Key words: phytoseiid mites, Typhloctonus, Ukraine.

Formation Peculiarities of Embryonic Pharynx
in Early Embryogenesis of the Planarian Dugesia lugubris (Turbellaria, Tricladida).
Kanana Yu. P. — We studied the formation of embryonic pharynx in early embryogenesis
of the planarian Dugesia lugubris O. Schmidt, 1861 using dated material. It is
shown that there is no formation of the embryonic gut in D. lugubris during this
time. The possibility that the embryonic pharynx can be considered as a case of
either recapitulation of some stage in the phylogenesis of the planarians or,
more likely, of embryonic adaptation, is discussed.
Key words: embryogenesis, turbellaria, planarian, embryonic pharynx, embryonic
gut.

Distribution, Biology of Development and
Ecology of the Mollusk Conventus conventus (Bivalvia, Pisidiidae) in Streams and
Small Lakes of the Northern Part of Murmansk Region. Frolov A. A. — C. conventus
is established to inhabit littoral zone of lakes with depth more than 14 meters.
It populates exclusively areas with abrupt slope of the bottom to the profundal.
Settlements of C. conventus in streams are registered for the first time. Based
on analysis of some environmental parameters of habitat (pH, stream velocity)
and comparison of obtained results with published data, a conclusion about wide
ecological flexibility of this species is made.
Key words: bivalvia mollusks, lakes, shoals, streams.

Host-Parasite Coevolutionary Relationships
of Mites of the Genus Riccardoella (Prostigmata, Ereynetidae) and Terrestrial
Mollusks. Akimov I. A., Zabludovska S. A. — In a laboratorial culture of parasitic
mites Riccardoella (Proriccardoella) oudemansi Thor, 1932 on their host — slug
Deroceras reticulatum (Gastropoda) — the behavior and host-parasite relationships
between these species and the effect of optimal and extreme conditions on the
parasite were studied on their host, slug Deroceras reticulatum (Gastropoda).
The development of R. (P). oudemansi from egg to mature stages, variation of the
number of each stage in the optimal and extreme conditions were traced. The negative
effect of mites on their host, a slug, while feeding leads to underdevelopment
and death of the host was detected. Parasitic status of R. (P). oudemansi was
elucidated to be not well-established with transition to the optional under the
extreme conditions.

parasitism, adaptation.

(upper side).

A Comparatively Kariological Analysis of
the Toads Bufo (Amphibia, Anura,) from Ukraine. Radchenko V. ²., Ìànilo V. V.
— Karyotipes of three species of toads Bufo bufo (Linnaeus, 1758), Bufo viridis
(Laurenti, 1768) and Bufo calamita (Laurenti, 1768) from the fauna of Ukraine
are examined: The diploid number consists of 22 chromosomes, NF = 44. Differences
among these three species occur in the morphology of chromosomes (the 10-th pair
of chromosomes in B. bufo has submetatsentrical structure, the others are metatsentrical;
the 4-th pair of B. viridis is is submetatsentrical, whereas the others are metatsentrical;
in B. ñalamita, the 11-th pair of chromosomes is subtelotsentrical, whereas the
others are metotsentrical) and by general length of karyotipe: 115,5 µm for B.
bufo, 102,8 µm for B. viridis, 105,5 µm for B. ñalamita. The secondary constrictions
are found on the short shoulder of the 10-th pair in the B. calamita and on the
long shoulder of 5-th pair of chromosomes in B. bufo. Sexual chromosomes are not
identified. Chromosomal formulas of B. bufo and B. viridis are — 2n = 20V + 2sV
= 22, NF = 44 and in B. calamita 2n = 20V + 2sT = 22, NF = 44.
Key words: toads, karyotype, humeral index, centromere index, Ukraine.
