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.
Key words: coevolution, Ereynetidae, slugs, biology, morphology, parasitism, facultative parasitism, adaptation.

Two New Species of the Genus Sycophila (Hymenoptera, Eurytomidae) from Yemen. Zerova M. D., van Harten A. Two new species of the genus Sycophila Walker from Yemen are described. Sycophila yemeni Zerova, sp. n. (type locality: Taizz, Yemen) is similar to Sycophila kestraneura (Masi) (Africa) but differs in shorter radial vein and longer gasteral petiolus in female. Sycophila setulosa Zerova, sp. n. (type locality: Taizz, Yemen) differs from all known Sycophila species in having the long bristles at the base of parastigma (upper side).

A Comparatively Kariological Analysis of the Toads Bufo (Amphibia, Anura,) from Ukraine. Radchenko V. ., nilo 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. alamita, the 11-th pair of chromosomes is subtelotsentrical, whereas the others are metotsentrical) and by general length of karyotipe: 115,5 m for B. bufo, 102,8 m for B. viridis, 105,5 m for B. alamita. 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.
