Abstract

The genus Hydroporus Clairville is the most diverse group belonging to the subfamily Hydroporinae in the family Dytiscidae. However, members of this group have not been recorded in the Korean peninsula. The genus Hydroporus Clairville is characterized by the following features: body glabrous to distinctly setose; elytra and ventral surface mainly piceous to black; epipleuron lacking a carina on humeral angle; metacoxal process conjointly with hind margin straight or slightly angulate medially. We collected the high mountain wetland and identified the species of Hydroporus uenoi Nakane based on male genitalia for the first time. A habitus photo, a redescription, mitochondrial DNA sequence, illustrations of the aedeagus of species, and habitat information are provided.
