This species can be distinguished from the other species of the hirtalis speciesgroup by the following combination of characters: antennomere 1 elongate, approximately 2.5 times longer than wide; posterior frontal fovea oval; eye small, one-third length of temple; hind wings welldeveloped; shape of genitalia unique to species.

Description. Length 2.7–3.3 mm. Body brown, elytra, legs, and maxillary palpi paler ( Fig. 3m ). Head: As long as wide, widest across eyes ( Fig. 3m ). Antennomere 1 approximately 2.5 times longer than wide, 2–3 subquadrate, 4–6 longer than wide, 7–10 subquadrate. Frontal sulcus deep and reaching hind point of eye from frontal rostral lobes. Anterior frontal fovea oval, posterior frontal fovea elongate. Eye small and prominent, onethird length of temple. Thorax: Prosternum as long as wide, widest at one-third length. Elytra rectangular ( Fig. 3m ). Hind wings well-developed. Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe longer than parameres, bearing small process from apex ( Fig. 4m ). Phallobase of median lobe asymmetrical and triangular ( Fig. 4m ). Right paramere divided into 2 branches with an additional minor branch divided into 2 branches apically ( Fig. 4m ).
