Rhabdias pearsoni sp. n. (Nematoda, Rhabdiasidae) from keelback, Tropidonophis mairii (Reptilia, Colubridae) in Australia. Kuzmin Yu. I., Tkach V. V. Rhabdias pearsoni Kuzmin et Tkach, sp. n. is described based on specimens found in the lung of the keelback Tropidonophis mairii (Gray, 1841) from southern Queensland, Australia. The new species is most similar morphologically to Rhabdias horigutii Yamaguti, 1943 and Rhabdias vibakari Kuzmin, 1999 with all three species lacking buccal capsule. The new species differs from R. horigutii by the smaller circumoral lips and papillae, and shorter tail. R. pearsoni sp. n. differs from R. vibakari by position of the nerve ring (in R. vibakari, it is closer to the anterior end than in the new species) and shorter tail. Australian R. pearsoni sp. n. is geographically isolated from R. horigutii and R. vibakari, both occurring in Eastern Asia.
Key words: Nematoda, Rhabdiasidae, Rhabdias pearsoni sp. n., snakes, keelback, Tropidonophis mairii, Australia.

New Species of Ants of the Genus Dolichoderus (Hymenoptera, Formicidae) from Late Eocene Ambers of Europe. Dlussky G. M. Nine new species of the ant genus Dolichoderus Lund from Late Eocene ambers of Europe are described: D. brevipalpis sp. n. (Baltic amber), D. brevipennis sp. n. (Bitterfeld amber), D. granulinotus sp. n. (Baltic amber), D. kutscheri sp. n. (Bitterfeld amber), D. lucidus sp. n. (Rovno amber), D. perkovskyi sp. n. (Rovno and Scandinavian ambers), D. pilipes sp. n. (Rovno and Scandinavian ambers), D. punctatus sp. n. (Baltic amber), and D. vlaskini sp. n. (Rovno amber). The key to species and information about distribution in different Late Eocene ambers are provided for the first time. In the Rovno and Scandinavian ambers, relative number and species diversity of Dolichoderus have found to be higher than in Baltic and Bitterfeld ambers.
Key words: Hymenoptera, Formicidae, Dolichoderus, ants, new species, key, Baltic amber, Bitterfeld amber, Rovno amber, Scandinavian amber.

Morphology of some Loricate Heterotrophic Species of Flagellate (Choanomonada, Bicosoecida, Jakobida), with Emphasis on Taxonomical Problems of Asexual Protist Species. Tikhonenkov D. V., Mazei Yu. A., Mylnikov A. P., Kireev A. V. Morphology of the some loricate heterotrophic flagellate species in the natural and clonal populations are investigated. Differential diagnoses and descriptions of species are provided. Some taxonomic problems of loricate heterotrophic flagellates and protists identification are discussed. A new replacement name Salpingoeca skujae Tikhonenkov et Mazey, nom. n. for Salpingoeca urnula Skuja, 1948, nom. praeocc., non Salpingoeca urnula Korshikov, 1926 is proposed.
Key words: morphology, heterotrophic flagellates, species descriptions.

The Structure and Functions of the Skin of Bats Flying Membrane (Vespertilionidae, Chiroptera). Kovalyova I. M. The data published till now about the constitution of the flying membrane skin in bats contain many contradictory items of information concerning individual structures. The author conducts researches in micromorphological constitution of the skin of flying membranes Nyctalus noctula and Eptesicus serotinus (Chiroptera), from the point of view of performing heat regulating and respiratory functions.

Morpho-functional analysis vessels bed of the tail samiaquatic rodents are given. Peculiarities of anatomical and histological structure of the main and peripheral vessels, which contribute to realization of thermoregulatory function and make blood vessels of the tail important part in the system of thermoregulation are noted.

Peculiarities of the Orientation Flight in Different Castes of the Honeybee Apis mellifera (Hymenoptera, Apidae). Lutsenko Yu. V. Using the video analysis, the orientation flight characteristics of different honeybee Apis mellifera Linnaeus castes are determined and differences between them are detected. The orientation flights of different bee castes differ by the speed, quantity of orientation turnings, by the time of flight fulfillment, when the bee flies backwards, and by the flight duration within the frame limit.
Key words: Hymenoptera, Apidae, bees, orientation flight, homing.

Description of a New Species of the Genus Globulencyrtus (Hymenoptera, Chalcidoidea, Encyrtidae) from Australia with Information on G. politus, the Type Species, a Parasitoid of Mites of the Family Caeculidae (Acarina). Trjapitzin V. A., Simutnik S. A. Globulencyrtus dahmsi Simutnik et Trjapitzin, sp. n. from Australia with unknown biology is described. Globulencyrtus Hoffer, 1975 was hitherto considered to be a monotypic genus. G. politus (Hoffer, 1957) is known as a single hymenopteran endoparasitoid of predatory mites of the family Caeculidae. Information on this species and on its host Microcaeculus steineri delamarei Coineau is provided. The new species differs from the type-species by the scutellum with two large and deep grooves in the base and by the arcuate vein of the forewing rudiments. Holotype of the new species is deposited in the collection of the Department of Entomology, University of California (Riverside, California, USA).
Key words: Encyrtidae, Globulencyrtus dahmsi, Australia, Globulencyrtus politus.
