Taxonomy

edit

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

edit

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

edit

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]
