Crephelochares Explained

Crephelochares is a genus of water scavenger beetle in the family Hydrophilidae represented by 29 described species.^[1] It is distributed across the Afrotropical, Australasian, Indo-Malayan, and Palaearctic realms.

Taxonomy

The genus Crephelochares was described for the first time by August Ferdinand Kuwert in 1890 ^[2] as a subgenus of the genus Helochares.

Then it was considered a synonym of Chasmogenus,^[3] but thanks to the results of a phylogenetic analysis involving molecular data,^[4] both taxa are now considered distinct genera on their own right.

Description

Small size (2.5–4.8 mm), bearing a clearly visible sutural stria; long maxillary palps; metafemora densely covered by hydrofuge pubescence.

A diagnosis was presented by Girón and Short.
