Rhynchotalona falcata (Crustacea: Anomopoda: Chydoridae): First recording in Slovakia with notes on its distribution and biology

Abstract

Rhynchotalona falcata (G.O. Sars, 1861) was found in the plankton of a gravel pit located in the lowlands of Slovakia. This is the first record of this taxon for Slovakia, although it is widely distributed in Western Europe. We do not know to date, whether it is a rare, native species of Slovakian fauna, or accidentally introduced one from north-west regions of Europe. Some notes on its biology and distribution in Europe are provided.
