Description
Oval; subconvex; head, pronotum, and scutellum black; elytra dark metallic blue; legs reddish. Head: vertex shallowly, sparsely punctate, without sulcus; frons not projecting; not depressed between eyes. Antenna: reaches to humerus; slender; antennomere 1 subglobose; 2 cylindrical, elongate, longer than 1; 3 elongate, longer than 1–2 combined; 4–10 elongate, decreasing in length, each shorter than 3; 11 pointed at apex, subequal in length to 4; 1–11 setose. Pronotum: transverse; lateral margin straight for basal ½ then rounding to anterior angle, canaliculate; anterior angle produced; posterior angle acute; anterior margin emarginate behind head; disc subconvex; with slight depression in posterior angle; surface impunctate; basal impression absent; pronotal length 0.6–0.9 mm; pronotal width 1.0–1.3 mm. Scutellum: pentagonal, impunctate. Elytron: lateral margin straight, dentate, especially on apical ½, margined; apex rounded; sutural angle without tooth; humerus rounded, slightly produced; slightly constricted behind humerus; punctures shallow; rows converge and unite near apex; punctures are larger and more impressed on elytral disc, rest almost obsolete; elytral length 2.6–3.3 mm; elytral width 1.4–1.7 mm. Venter: pro-, meso-, and metasterna smooth medially, punctate laterally; abdominal sterna punctate, each puncture with pale seta; suture between sterna 1 and 2 obsolete medially, punctate laterally. Leg: slender; punctate; femur and tibia with row of setae on inner margin; tibia with fringe of setae on inner margin of apex. Total length: 3.4–4.1 mm.
Diagnosis
This is a distinctive species which can be distinguished by the metallic blue color, by the smooth lateral margins of the pronotum, and by the serrulate lateral margins of the elytra.
Host plant
Adults have been collected on Chusquea sp. (Poaceae) (Staines 1996[1]).
Distribution
Colombia, Costa Rica, Venezuela.
