Diagnosis. This species is similar in appearance to other members of this species-group but can be distinguished by the horn on the ventral surface of the male head being shorter in length than width and the shape of the antennae and genitalia.

Redescription. Length 2.5–2.8 mm. Body brown, antennae, legs, and maxillary palpi paler, elytra yellowish brown ( Fig. 27a ). Head: Transverse ( Fig. 27e ). Antennomeres 2–3 subquadrate, 4–7 longer than wide, 8–10 subquadrate. Eye small and prominent, one-third length of temple ( Fig. 27e ). Horn on ventral surface of male head triangular and shorter in length than width. Thorax: Prosternum as long as wide, widest at one-third length. Elytra approximately triangular ( Fig. 27a ). Meso- and metathorax trapezoidal, as long as wide. Aedeagus: Median lobe branched into 3 lobes, as long as left paramere, major lobe triangular ( Fig. 27c ). Phallobase of median lobe symmetrical and rounded ( Fig. 27c ). Parameres asymmetrical with acute bent apices, left paramere longer than right ( Fig. 27c ).
