Hydroporus subpubescens
Hydroporus subpubescens is a predaceous diving beetle in the family Dytiscidae, described by LeConte in 1852. The species was transferred from the subpubescens-group to the nigellus-group based on extreme morphological similarity to H. tenebrosus, resulting in the elimination of the subpubescens-group as a formal grouping. It is known from North America.
