Description.

Small, elongate; subparallel; subdepressed; black, pronotum and elytra with paler margins. Head: vertex densely punctate, medial sulcus absent; frons densely punctate, not projecting; not depressed between eyes. Antenna: slightly longer than head and pronotum combined; slender, slightly thickened apically; antennomeres 1-2 transverse, subequal in length, 1 not thickened; 3 elongate, slightly longer than 1 or 2; 4-10 transverse, subequal in length, each shorter than 2; 11 2 × length of 10, pointed at apex. Pronotum: slightly wider than long; lateral margin straight then abruptly rounding to anterior angle, canaliculate; anterior angle rounded, slightly produced; posterior angle angulate; anterior margin sinuate; disc transversely subconvex; surface deeply but not densely punctate; basal impression absent; pronotal length 0.7-0.9 mm; pronotal width 1.0-1.1 mm. Scutellum: pentagonal; alutaceous. Elytron: lateral margin straight, smooth, margined; apex obtusely rounded; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, rows converge and unite apically; elytral length 2.6-2.7 mm; elytral width 1.3-1.4 mm. Venter: pro-, meso-, and metasterna impunctate medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete; last sternite with apical margin emarginate medially in male, truncate in female. Leg: slender; punctate, each puncture with pale seta; femur robust; tibia with fringe of setae on inner margin of apex. Total length: 3.4-3.6 mm.

Diagnosis.

This small black species is recognized by the head not being depressed between the eyes, by the vertex of the head being densely punctate, and by the canaliculate lateral margins of the pronotum.
