Head: vertex smooth, depressed, with scattered punctures in depressed area, small carina present between base of antennae; frons smooth, not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 elongate, thicker than others; 2 cylindrical, subequal in length to 1; 3 cylindrical, slightly longer than 2; 4-10 cylindrical, elongate, decreasing in length; 4 shorter than 3; 11 2 × length of 10, bluntly pointed at apex; 1-2 punctate; 3-11 setose. Pronotum: transverse; lateral margin straight for basal ½ then rounding to anterior angle, canaliculate; anterior angle with broad, blunt tooth; posterior angle acute; anterior margin emarginate behind head; disc flattened; surface sparsely, coarsely punctate; basal impression absent; pronotal length 1.4-1.5 mm; pronotal width 1.6-1.9 mm. Scutellum: triangular, impunctate. Elytron: lateral margin straight, smooth, slightly laminate; apex rounded, smooth; sutural angle with small tooth; humerus rounded, not produced; slightly constricted behind humerus; moderately punctate-striate, puncture rows confused apically; elytral length 5.0-5.2 mm; elytral width 2.2-2.6 mm. Venter: pro-, meso-, and metasterna impunctate medially, coarsely punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin rounded entire in male, truncate in female.
