Agraphydrus is a genus of water scavenger beetle in the family Hydrophilidae represented by 205 described species. [1] It is distributed across the Afrotropical, Australasian, and Indomalayan realms.

Taxonomy

The genus Agraphydrus was described for the first time by Régimbart in 1903. [2]

It currently contains 205 described species, partly thanks to a series revisionary work developed by Albretch Komarek. [3] [4] [5] [6] [7]

Description

Small beetles (1.4–4.8 mm), pale/yellowish to dark brown in coloration, eyes not emarginate, labrum exposed, maxillary palps moderately long. Elytra without sutural striae, not laterally explanate; the elytral punctation ranges from very fine and subtle to coarse.

A complete diagnosis was presented by Girón and Short, [1] but also see Komarek and collaborators. [3] [4] [5] [6] [7]

Habitat

According to Girón and Short, [1] based on annotations by Komarek and collaborators: [3] [4] [5] [6] [7]

Agraphydrus can be found in an extremely broad range of habitats, from rivers, streams and forest pools, to hygropetric environments around waterfalls or seepages over rocks; a few species have been collected in terrestrial habitats by sifting moss and leaves from near water bodies, or in the gravel along the bank of a river; in many cases specimens have been found associated with floating vegetation, mosses and algae. [1]
