Description.

Elongate; subparallel; subdepressed; head dark with metallic sheen, mouthparts reddish-brown; pronotum black with reddish lateral margins; scutellum black with reddish middle; elytra yellowish-brown with suture and apex darker; venter black; legs black with base of femur and apex of tibia reddish. Head: vertex distinctly, finely punctate, medial sulcus absent; frons not projecting; depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1-10 cylindrical; 1 subequal in length to 2, cylindrical; 2 ¾ length of 3; 3 cylindrical, longer than 1, longest; 4-10 subequal in length, cylindrical, each shorter than 2; 11 2 × length of 10, pointed at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse; lateral margin straight then rounding to anterior angle, margined; anterior angle rounded, not produced; posterior angle acute; anterior margin emarginate behind head; disc convex; surface finely punctate with medial longitudinal impunctate line; transverse basal impression present medially; pronotal length 1.1-1.2 mm; pronotal width 1.4-1.5 mm. Scutellum: pentagonal; impunctate. Elytron: lateral margin straight, smooth, rounded on apical ⅓; apex weakly rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; finely punctate-striate, punctures larger in rows 6-9, rows 5-6 obsolete before apex, rows converge and unite apically; elytral length 3.4-3.5 mm; elytral width 1.5-1.6 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin emarginate medially in male, rounded, entire in female. Leg: robust; femur rugose; tibia deeply incised apically with fringe of setae apically. Total length: 4.7-5.0 mm.
