This species can be distinguished from the other species of the anisarthra speciesgroup by the following combination of characters: body length 2.9–3.2 mm; antennomeres 4–11 bearing tubercles; frontal sulcus shallow, reaching midpoint of eye; anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea oval; eye large and prominent, one-third length of temple; male abdominal ventrite VII deeply emarginate and surrounded by dense setae; shape of antennomeres and genitalia unique to species.

Description. Length 2.9–3.2 mm. Body reddish brown, antennae, elytra, legs, and maxillary palpi paler ( Fig. 45e ). Head: Male head bluntly triangular, widest across eyes ( Fig. 45e ). Antennomere 1 approximately 2 times longer than wide, 2–3 subquadrate, 4–5 longer than wide, 6–10 subquadrate, 4–11 bearing tubercles. Frontal sulcus shallow, reaching midpoint of eye. Anterior frontal fovea round, partially covered by frontal rostrum, posterior frontal fovea oval. Eye large and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at one-third. Male elytra rectangular ( Fig. 45e ), female elytra triangular. Male hind wings well-developed, female hind wings reduced to small pads. Meso- and metathorax trapezoidal, as long as wide. Abdomen: Tergite IV without patches of microtrichia. Male abdominal ventrite VII deeply emarginate and surrounded by dense setae.
