Redescription of Hydrobius pauper (Coleoptera: Hydrophilidae), with a key to the Eurasian species of the genus Hydrobius

S.K. Ryndevich & R.B. Angus

Abstract. The little-known water scavenger beetle Hydrobius pauper Sharp, 1884 has only ever been recorded from Japan. Based on the type series, the species is redescribed and its diagnostic features are clarified. The lectotype of H. pauper is designated. This species is compared with other Eurasian representatives of the genus Hydrobius Leach, 1815. A key to all Eurasian species of the genus is given.
