Study of Biology, Morphology and Taxonomy of the Nematode Stephanofilaria assamensis (Filariina, Stephanofilariidae). Saparov K. A., Akramova F. D., Azimov D. A., Golovanov V. I. — Biological characters of Stephanofilaria assamensis Pande, 1936, a parasite of cattle, were studied under environmental conditions of Uzbekistan with the emphasis on morphology of all developmental stages. Bloodsucking flies Haematobia atripalpis Bezzi, 1895, Lyperosia titillans Bezzi, 1907 and L.irritans Linnaeus, 1758 were established as intermediate hosts. Prevalence of the nematode larvae in the flies constituted 2.1, 1.5, and 1.2 %, respectively. Characters for the species identification were revised. On that basis S. zaheeri Singh, 1958 is regarded as a synonym of S. assamensis. The place of Stephanofilaria genus in the system of Stephanofilariidae is discussed.


Fauna and distribution patterns of the endohelminths of Cypriniformes from water bodies of the mid-course of the Syrdarya River were investigated. Forty-nine endohelminth species were recorded from Cypriniformes in this region, including 18 species of trematodes, 13 species of cestodes, 14 species of nematodes and 4 species of acanthocephalans. Twenty-nine species are first reported from this region. Original data on the composition and structure of endohelminth communities are given.
