Abstract

Suphrodytes Des Gozis is shown, on the basis of the morphology of the prosternal process and the arrangement of the fertilisation tract of the female, to be a valid genus, with one species, Dytiscus dorsalis Fabricius, 1787. The northern Palaearctic species, Hydroporus arcticus Thomson, 1854, H. tomentosus Poppius, 1905, H. submuticus Thomson, 1875 and H. lapponurn Gyllenhal, 1808, formerly placcd together with S. dorsalis in Hydroporus (Suphrodytes) are shown to be good Hydroporus. Hydroporus arcticus and H. tomentosus are sunk as subspecies of the Nearctic H. notabilis LeConte, 1850.
