Elongate; ovate; subconvex; shining; yellowish-brown; head, antennae (except antennomere 1 brownish) black; elytra with black sutural marking; venter with pro-, meso-, metasterna and abdominal sternite 1 yellowish-brown medially, black laterally, sterna 3-5 yellowish-brown. Head: vertex punctate, medial sulcus absent; frons not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 slightly incrassate, 2 × length of 2; 2 subglobose, elongate; 3-5 cylindrical, subequal in length, each longer than 2; 6-10 transverse, subequal in length; 11 2 × length of 10, broadly rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin sinuate at base, straight after middle then rounding to anterior angle, finely margined; anterior angle rounded, not produced; posterior angle acute; anterior margin straight; disc subconvex; surface densely punctate; basal impression absent; pronotal length 0.9-1.1 mm; pronotal width 1.2-1.4 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex broadly rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, rows converge and unite apically; elytral length 3.3-3.7 mm; elytral width 1.5-1.7 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially; last sternite with apical margin emarginate medially in male, truncate in female.
