Etymology. This species is named for the collector of the holotype, Robin C. Craw.

Description. Length 2.6–3.0 mm. Body brown, elytra, legs, and maxillary palpi paler ( Fig. 11c ). Head: As long as wide, widest across eyes ( Fig. 11c ). Antennomere 1 approximately 2 times longer than wide, 2–5 longer than wide, 6–10 subquadrate. Frontal sulcus deep and reaching hind point of eye from frontal rostral lobes. Anterior frontal fovea an inverted triangle. Posterior frontal fovea elongate. Eye small and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra approximately triangular ( Fig. 11c ). Meso- and metathorax trapezoidal, longer than wide. Abdomen: Male tergite IV without microtrichial patch. Aedeagus: Median lobe shorter than parameres, apical lobe simple ( Fig. 12c ). Phallobase of median lobe asymmetrical and triangular ( Fig. 12c ). Parameres asymmetrical, right paramere twisted, broad apically ( Fig. 12c ).
