Redescription and taxonomic status of Pleurhomus sahlbergi Sharp, 1883 (Coleoptera, Hydrophilidae)

The genus Pleurhomus and its sole species P. sahlbergi have been only poorly characterized, both in the original description and in subsequent treatments. A full redescription of the adults of both sexes is given; the larvae remain unknown. On the basis of the emargination in the last apparent urost...

Adult morphology Homostethus Pristoternus South America Strepitornus Subgeneric placement Tropisternus Coleoptera Hydrophilidae Tropisternus The genus Pleurhomus and its sole species P. sahlbergi have been only poorly characterized, both in the original description and in subsequent treatments. A full redescription of the adults of both sexes is given; the larvae remain unknown. On the basis of the emargination in the last apparent urosternite, the untoothed claws in all pairs of legs, in both sexes, the short but evident series of punctures on the elytra, the minute notch at the distal end of the elytral commisure, and the depressed apical segment in the antenna, Pleurhomus clearly differs from Tropisternus. However, until the species of this genus, and especially those of the subgenus Homostethus, are better known, the subgeneric status of Pleurhomus within Tropisternus is here maintained, along with Homostethus, Strepitornus, Pristoternus and Tropisternus.
