Diagnosis. This species can be identified by the following characters: penis capsule looks like a hammer and apex of penis with 8 to 10 minutely dentate, apically with a long, thread-like appendage. Its parameres relatively broad, shorter than penis guide, 3/4 length of the latter.

Description. TL: 2.28 mm, TW: 1.64 mm, TH: 1.00 mm, TL/TW: 1.39, PL/PW: 0.5, EL/EW: 1.17.

Head small, 0.57× of pronotal width (HW/PW=0.68/1.20). Punctures on head similar with eye facets, separated by 1–2 diameters, with golden yellow pubescence. Eyes small, the widest interocular distance 0.47× of head width. Pronotum about 0.73× of elytral width (PW/EW=1.20/1.64), pronotal punctures fine, 1–2 diameters apart. Surface of elytra with dense punctures, separated by 1.5–2 diameters. Prosternal carinae nearly parallel, extending to anterior margin. Prosternal process trapezoid, length 3.5 times of width at the base. Abdominal postcoxal lines incomplete (Fig. 23). Area surrounded by the line evenly punctured, narrowly smooth along the line.

Male genitalia: Penis slender, penis capsule hammer-like in lateral view (Fig. 24). Apex of penis with 8 to 10 minutely dentate, apically with thread-like appendage, forming a round shape (Fig. 25). Tegmen moderately stout, penis guide nearly parallel, converges gradually apically to a pointed tip in ventral view (Fig. 27). Parameres relatively broad, distinctly shorter than penis guide, 3/4 length of the latter, apex with two groups of nearly uniform setae oriented in different directions (Fig. 26). Female genitalia unknown.
