Pronotum: transverse; lateral margin straight basally then rounding to anterior angle, with lenticular swelling anteriorly, margined; anterior angle rounded, slightly produced; posterior angle acute; anterior margin weakly emarginate behind head; disc subconvex; disc micropunctate, scattered larger punctures present laterally; basal impression absent; pronotal length 1.4 mm; pronotal width 1.0 mm. Scutellum: pentagonal; punctate. Elytron: lateral margin straight, smooth, margined; apex obliquely rounded, smooth; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; shallowly punctate-striate, rows converge and unite apically; elytral length 2.9 mm; elytral width 1.6 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 complete. Leg: slender; coxae coarsely punctate; trochanter, femur, and tibia punctate, each puncture with pale seta; tibia with fringe of setae on inner apical margin. Total length: 3.9 mm.

Etymology.

Lenticula (Latin) meaning lens for the lens-shaped swelling on the lateral margin of the pronotum. The name is feminine.

Diagnosis.

This is a very distinctive species which can be distinguished by the brown color and the lens-like swelling on the lateral margin of the pronotum.
