Redescription

Female. Integument almost entirely black. Head and prothorax orangish, concolorous. Forelegs or, at least the profemora, reddish. Vertex, frons, clypeus, genae and margin of lower eye lobes densely clothed by silky, golden-yellowish pubescence. Clypeal suture inconspicuous. Mandibles sparsely yellowish pubescent.

Antennae reaching apical third of elytra. Scape sparsely yellowish pubescent. Segments 3–5 almost cylindrical, practically not expanded at apex, finely punctuate, clothed by yellowish pubescence; segments from 6 with yellowish pubescence gradually denser to distal segments; 6–10 decreasing in length and slightly expanded at apex; 11 subcylindrical, little longer than 3.

Prothorax subparallel at sides, base as wide as middle, then slightly attenuate to apex. Pronotum somewhat depressed at apical third, clothed with yellowish pubescence; latero-basal gibbosities prominent, subacuminate. Sides of prothorax sparser pubescent. Prosternum with whitish pubescence, especially at posterior half.

Elytra subparallel at sides. Disk slightly depressed, without dorsal costa. Surface densely punctuate; punctures moderately coarse, not seriate, separated by less than one diameter, becoming finer, denser to corrugate apically. Clothed with short, whitish pubescence not obscuring punctures, and with some whitish, erect setae denser at apical third. Epipleura densely whitish pubescent. Margins weakly asperate, the asperities far from each other. Elytral apices truncate.

Peduncles of femora conspicuously sulcate. Metafemora reaching elytral apices. Metatibiae straight. First segment of metatarsi 1.3 times longer than the following two combined.

Measurements (mm) female. Total length, 7.2; prothorax length, 1.7; maximum width of prothorax, 1.3; elytral length, 5.1; humeral width, 1.6.
