Abstract

We report findings of 43 species of rare or previously unknown species of water beetles from the Czech Republic. One species of the Hydrophilidae, Dactylosternum abdominale (Fabricius, 1792), is new to the Czech Republic. We confirm the presence of the following three species in the Czech Republic: Enochrus hamifer Ganglbauer, 1901 (Hydrophilidae, recent record from Moravia), Hydraena reyi Kuwert, 1888 (Hydraenidae, recent record from both Bohemia and Moravia) and Heterocerus parallelus Gebler, 1830 (Heteroceridae, old record from Bohemia). Dryops anglicanus Edwards, 1909 (Dryopidae) is recorded as new to Moravia, based on a recent record. We also confirm recent occurrence of Dytiscus semisulcatus O. F. Müller, 1776, Nebrioporus assimilis (Paykull, 1798) and Oreodytes septentrionalis (Gyllenhal, 1827) (all Dytiscidae) in Bohemia and of Colymbetes striatus Linné, 1758, Hydroporus marginatus (Duftschmid, 1805) (both Dytiscidae), Hydraena minutissima Stephens, 1829 (Hydraenidae) and Pomatinus substriatus (Ph. Müller, 1806) (Dryopidae) in Moravia. At present, 405 species of water beetles are known from the Czech Republic: one species of the Sphaeriusidae, 11 species of the Gyrinidae, 18 species of the Haliplidae, one species of the Hygrobiidae, two species of the Noteridae, 132 species of the Dytiscidae, 28 species of the Helophoridae, three species of the Georissidae, six species of the Hydrochidae, one species of the Spercheidae, 79 species of the Hydrophilidae, 53 species of the Hydraenidae, 24 species of the Scirtidae, 19 species of the Elmidae, 12 species of the Dryopidae, four species of the Limnichidae, 10 species of the Heteroceridae, and one species of the Psephenidae.
