New Genera and Species of the Family Hydrophilidae (Coleoptera) from Turkey

Two hydrophilid genera, Cymbiodyta Bedel 1881 and Chasmogenus (Watanabe, 1987), and 3 species, Cymbiodyta marginella (Fabricius. 1792), Enochrus (Methydrus) coarctatus (Gredler, 1863), and Chasmogenus (Crephelochares) orbus (Watanabe, 1987), are reported for the first time from Turkey. The ecological findings and morphological characters of these species are described, and their aedeagi are illustrated. Biological observations and distribution records for all the newly recorded species are also presented. Diagnostic characters are supported with microscope micrographs.
