Description.

Elongate; subdepressed; shining; reddish-brown; antennomeres 1-4 yellow, 5-11 darker; eyes darker. Head: vertex sparsely punctate, medial sulcus present; frons not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomeres 1-4 laterally compressed, with inner anterior angle produced into acute tooth in male, elongate in female; 1 large, clavate; 2-4 subequal in length, each shorter than 1; 5-10 transverse, decreasing in length, each shorter than 4; 11 pointed at apex, subequal to 1; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin straight for basal ¾ then convergent, margined; anterior angle produced, obtuse; posterior angle angulate; anterior margin emarginate behind head; surface finely, sparsely punctate; basal impression absent; pronotal length 1.3-1.8 mm; pronotal width 2.0-2.6 mm. Scutellum: triangular; impunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; weakly punctate-striate; elytral length 5.1-6.4 mm; elytral width 2.7-3.3 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 truncate in female, emarginate medially in male. Leg: femur and tibia punctate, each puncture with pale seta; femur robust; tibia expanded to apex, with fringe of setae on inner margin of apex. Total length: 6.9-8.4 mm.

Diagnosis.

This is one of the reddish-brown immaculate species. It can be distinguished from the other reddish-brown species by the suture between abdominal sterna 1 and 2 being complete and by antennomere 1 being as long as 2 to 4 combined.

Distribution.
