Abstract

Diacyclops cohabitatus Monchenko 1980 known only from the groundwater of the Carpathian mountains in Ukraine is redescribed from specimens collected in the Danube alluvial plain, the Lobau, at Vienna. In this area two stygobiont species belonging to the D. languidoides - group co-occur as well. D. cohabitatus can be differentiated from these latter Diacyclops species on the basis of several morphological traits of antennae, P4 and caudal rami. Its relationship with other members of the D. languidoides - group (e.g. D. languidoides goticus) is discussed.
