Description.

Body length 2.10-2.54 mm, width 1.18-1.40 mm. Vertex and part of head below vertex including frons and antennal calli black with dark greenish to blueish tint. Antennomere 11 slightly lighter than 9. Base of pronotum dark yellow, slightly lighter in color than apex. Antebasal pronotal impression absent. Elytral disc black to dark brown with dark greenish to blueish tint. Some spots on elytron appear black in part because elytral surface darker, in part because it is covered with dark setae. In dorsal view dark spots are: one spot lateral to scutellum, two spots down posteriorly near suture, and two more on posterior slope; one spot on humeral callus, two spots behind each other on lateral slope near middle, and another spot directly below it towards posterior. Elytra laterally and towards apex also appear darker. Ventral side of body dark brown, except last abdominal segment being lighter in color. Pro- and mesofemora and pro- and mesotibiae brown, with slightly lighter area on tibiae. Metafemora dark, with bronzy shine. Metatibia uniformly brown to dark amber in color. Setae on orbit and vertex whitish, denser and more vivid on orbit, directed ventrally. Setae on middle of vertex short, directed towards middle, not forming a small “mohawk”. Pronotal setae more erect, directed laterally and posteriorly. Second row on punctures on elytral slope not impressed with setae directed laterally and ventrally from it. Median lobe of aedeagus narrows gradually from middle to apex in ventral view with wide apex.
