Description.

Elongate; subparallel; flattened; blackish-blue with reddish yellow markings; head with frons yellowish; venter black except prosternum and legs yellow. Head: vertex punctate, with inverted V-shaped sulcus between eyes; frons punctate, not projecting; not depressed between eyes. Antenna: reaches to humerus; robust; antennomere 1 very large, as long as 2-3 combined, laterally flattened and punctate, in male, a backward projecting tooth at base and smaller tooth near apex, female with antennomere 1 not as robust and smaller basal tooth; 2 smaller, narrower than 1, inner angle produced at apex; 3 longer than but similar shape to 2; 4 shortest; 5-10 transverse, subequal in length; 11 2 × length of 10, pointed at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin straight and divergent for basal ⅔ then rounding to anterior angle, margined; anterior angle rounded, produced; posterior angle angulate; anterior margin emarginate behind head; disc flattened; surface almost impunctate; basal impression absent; pronotal length 1.1-1.4 mm; pronotal width 1.9-2.0 mm. Scutellum: triangular; pointed at apex; impunctate. Elytron: lateral margin straight, smooth, narrowly margined; apex rounded; sutural angle without tooth; humerus rounded, slightly produced; slightly constricted behind humerus; declivity beginning just behind humerus along puncture row 7 with weak carina; shallowly punctate-striate; elytral length 4.9-5.7 mm; elytral width 2.3-2.8 mm. Venter: prosternum impunctate; 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 in female. Leg: robust; punctate; profemur enlarged; tibia with fringe of setae on inner margin of apex. Total length: 6.0-7.8 mm.
