Updated checklist and distribution of the inland-water calanoid copepods (Copepoda: Calanoida) of Romania

No recent studies on the distribution of calanoid copepods in Romanian inlandwaters are available. During a long-term survey aimed at large branchiopods, we collected two diaptomid species that are new for the fauna of the country, and supplemented the available data on the distribution of other calanoid species with new records. As already observed in the case of large branchiopods, the habitats of the mountain basins of the Eastern Carpathians seem to be characterized by a quite distinct species assemblage. The high calanoid species richness of Romanian inland-waters, and the need for further, more comprehensive surveys aimed at mapping the actual diversity of this order in Romania are stressed.
