DIAGNOSIS

Dimension. Body length (pronotum–elytra) 15.9–15.0 mm; width 3.1–5.5 mm.

Color. Integument black; vestiture gray and brown, dense, conspicuous; ventral segments gray and dorsal segments brown ( Figs. 1 and 2 ). Pronotum medially and laterally with 3 brown stripes. Elytra covered with gray, brown, and white hairs in hieroglyphic form. Female pygidium with 2 vertical glabrous lines. Hind femur with terminal part glabrous.

Head elongate; frontal carina present. Eyes flat, emarginate to 2/5 length of eye. Antennal articles 1–4 subcircular, 5 isosceles right triangle, 6–11 pectinate. Pronotum subtrapezoidal ( Fig. 1 ), with greatest width at base (W/L = 1.20), slightly rounded in middle of sides. Metasternal process strongly convex in lateral view. Elytra longer than wide, about 1.15 times longer than combined width; humeral callus distinct. Pygidium longer than wide. Hind femur strongly incrassate, dorsal side granulate, pecten with 1 large, sharp spine with 6 gradually smaller, blunt denticles following; 3 small spines before pecten ( Fig. 3 ).

Male genitalia. Median lobe elongate and sclerotized ( Fig. 5 ); lateral lobes fused into gutter-like structure ( Fig. 4 ); apex of lateral lobes densely pubescent.

Female genitalia. Ovipositor 2.5 times longer than wide, weakly sclerotized ( Fig. 6 ). Stylus with 2 short setae ( Fig. 7 ). First pair of baculum elongate, almost 2 times longer than 2nd pair ( Fig. 6 ). Apodeme of spiculum gastrale extending to apex of genitalia. Plate of spiculum gastrale longer than apodeme.
