Abstract

Results of investigation of the benthic crustacean fauna (Copepoda, Harpacticoida) are presented in the paper. Harpacticoids were investigated in the springs located in territories of the basins of the rivers Tisza (Danube basin) and Dniester within Ukraine. Harpacticoids were found in 46 microzoobenthos samples from the springs. In total, 18 species of Harpacticoids were identified, among them 14 species were found in the springs of the Tisza river basin, and 17 species were registered in the springs of the Dniester river basin. The species of Attheyella (Attheyella) crassa, Attheyella (Attheyella) wierzejskii wierzejskii, Bryocamptus (Bryocamptus) tarnogradskyi, Bryocamptus (Limocamptus) luenensis, Bryocamptus (Rheocamptus) spinulosus occidentalis were found most often in microzoobenthos samples. Bryocamptus (Bryocamptus) minutus minutus, Moraria (Moraria) brevipes brevipes, Proserpinicaris gorganensis were recorded for the Tisza basin once only. Bryocamptus (Bryocamptus) vejdovskyi vejdovskyi, Elaphoidella bidens decorata were recorded once for the Dniester basin. A comparison of the species composition of Harpacticoids according to the Jacquard index showed the similarity of the fauna of the springs of the Tisza and different areas of Dniester basins in the range of 0.41–0.23.
