Allocotocerus

Allocotocerus is a genus of water beetles in the family Hydrophilidae, first described by Ernst Gustav Kraatz in 1883. The decision for synonymy is based on Hansen (1999).

The Australian beetles of this genus are found in Western Australia, the Northern Territory and Queensland.

Watts separates the three genera of Hydrophilidae (Amphiops, Allocotocerus, and Regimbartia) which occur in Australia, by describing species from the genus Allocotocerus as being black, of length 3.5—4.5 mm, having meso- and meta-tibiae with swimming hairs, normal eyes, and elytra as long as high and having almost no striae.
