Elongate; subparallel; subdepressed; reddish-brown, eyes and apex of antennae blackish. Head: vertex sparsely punctate, medial sulcus absent; strong keel present between antennal bases; frons not projecting; slightly depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 incrassate, with projection on outer apical angle; 2 transverse, ⅓ length of 1; 3 widening apically, subequal in length to 2; 4-10 transverse, subequal in length, each shorter than 3; 11 2 × length of 10, pointed at apex; 1-3 punctate with scattered setae; 4-11 setose. Pronotum: transverse; lateral margin straight for basal ¾ then rounding to anterior angle, margined; anterior angle rounded, produced; posterior angle acute; anterior margin emarginate behind head; disc flattened; surface sparsely, shallowly punctate; basal impression absent; pronotal length 1.1-1.3 mm; pronotal width 1.4-1.9 mm. Scutellum: pentagonal, micropunctate. Elytron: lateral margin straight, smooth, margined; apex rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, rows converge and unite apically; elytral length 3.7-4.4 mm; elytral width 2.1-2.3 mm. Venter: prosternum impunctate medially, rugose laterally; meso- and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially.
