Diagnosis. This species can be distinguished from the other species of the baiknami speciesgroup by the following combination of characters: smaller body, length 2.4 mm; male head triangular, widest across temples, ventral temporal lobe flat; male mid-femur weakly depressed at base and mid-tibia bent; shape of antennomeres and genitalia unique to species.

Description of Male. Length 2.4 mm. Body brown, antenna, elytra, legs, and maxillary palpi yellowish brown ( Fig. 15g ). Head: Head triangular, widest across temples, ventral temporal lobe flat ( Fig. 15g ).

Frontal sulcus deep and reaching midpoint of eye from frontal rostral lobes. Anterior frontal fovea round. Posterior frontal fovea oval. Eye large and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at midpoint. Elytra rectangular ( Fig. 15g ). Meso- and metathorax trapezoidal, longer than wide. Male mid-femur weakly depressed at base. Male mid-tibia bent. Abdomen: Tergite IV with pair of oval or transverse patches of microtrichia. Aedeagus: Median lobe rectangular and blunt ( Fig. 16g ). Phallobase of median lobe asymmetrical and triangular ( Fig. 16g ).
