Comparison of nucleotide sequences of ribosomal DNA of the mosquito genera Aedes and Ochlerotatus (Diptera: Culicidae: Aedini). P. 3-10.
Morphological study allowed identifying 9 species of mosquitoes of the genus Ochlerotatus and 2 species of the genus Aedes. Sequencing of the rDNA region was performed for all these speciemens. The sequences of rDNA were the following: A. cinereus — 868 bp, A. vexans — 889 bp, Och. cantans — 803 bp, O. excrucians — 801 bp, O. euedes — 794 bp, Och. cyprius — 777 bp, O. diantaeus — 758 bp, O. intrudens — 817 bp, Och. punctor — 783 bp, O. dorsalis — 748 bp, O. species — 767 bp. On average, the size of Aedes rDNA fragments exceeds rDNA of Ochlerotatus by 90—100 bp. The sequences are characterized by a high number of insertions and deletions, and also by point substitutions of nucleotides. It is important to notice that interspecific differences include not only different regions of the internal transcribed spacers, but also the conservative site which is represented by the 5.8S gene. Among four substitutions in this gene, one (C/A) represents the difference between Aedes and Ochlerotatus, the next (T/A) distinguishes A. cinereus from Ochlerotatus speciment and A. vexans, and two substitutions (A/C, T/G) testify the similarity between O. dorsalis and O. species and specimens of Aedes. Besides, two more deletions are typical for O. dorsalis and O. species. One deletion is common, it distinguishes them from the other examined species, and another one is typical only for O. dorsalis. When analyzing morphological characteristics and comparing nucleotide rDNA sequences of O. species with the database, the similarity to O. caspius has been revealed. On the whole, phylogenetic relationships among Ochlerotatus species correspond to subdivision into groups based on morphological characters. Probably, examination of the larger number of specimens will change the morphological division into groups.

Variability of the dimensional structure in the hemipopulation of Thominx neopulchra (Nematoda: Capillariidae) females from bats of the genus Myotis (Chiroptera: Vespertilionidae). P. 11-15.
Variability of the dimensional structure in the hemipopulation Thominx neopulchra females from 3 species of the genus Myotis bats in the Zhiguli State Reserve was examined. The size of T. neopulchra from different bat species varied within the limits constituting 10.17—13.41 mm. It was demonstrated that the variability of the dimensional structure in the subpopulation group T. neopulchra from Daubenton's bats did not depend on the number of parasites in the host and the season and is probably determined by the genetic polymorphism of the parasite population.

Morphology and taxonomy of two new cercariae of the group Microcotylae. P. 16-26.
Two new microcotylous cercariae are described. Their morphology is described and the differential diagnoses is given. All description are allustrated. For the first time, taxonomy of some microcotylous cercariae is discussed on the basis of their basic morphology.

A new nematode species, Physaloptera musayevi sp. n., from the lybian jird Meriones libycus and the social vole Microtus socialis in the Gobustan area of Azerbaijan republic. P. 27-33.
Nematodes belonging to the genus Physaloptera Rudolphi, 1819 were obtained from the Lybian jird Meriones libycus and the social vole Microtus socialis in the Gobustan area as a result of helminthological research. These nematodes significantly differed from other species of the genus in morphological and morphometric characters. In the present paper, they are described as the new species Physaloptera musayevi sp. n.

A checklist of protozoan and metazoan parasites of the burbot (Lota lota). P. 34-61.
The parasite fauna of the burbot (Lota lota) within its natural range is reviewed. The sent paper summarizes the data on parasites of the burbot from water bodies of Eurasia and North America, based on published monographs, reviewed journals, scientific reports, conference contributions, and PhD theses. The checklist includes all protozoan and metazoan parasites of the burbot. A total of 242 parasite species/taxa were recorded in the burbot (Kinetoplastomonada — 4, Parasitomonada — 3, Coccidiomorpha — 1. Microsporidea — 3, Myxosporidia — 35, Pleurostomata — 1. Cyrtostomata — 3, Peritricha — 20. Protozoa incertae sedis — 1. Monogenea— 8, Cestoda — 23, Digenea— 50. Nematoda— 36, Acanthocephala — 28, Hirudinea — 11. Bivalvia — 5, Crustacea — 10). Most parasites belong to digenean trematodes. Most of these species (183 species/taxa) were recorded on Eurasian and only 92 — in North America fishes. Several parasite species recorded from the burbot are discussed in relation to host specificity and their geographical distribution.
