Head clothed with dark brown scales, punctures similar to punctures on rostrum; vertex with two patches of overlapping scales, whitish or pale yellow color, light brown on lateral margin; frons moderately concave; rostrum moderately robust, weakly carinate, apical area punctuate, eyes moderately convex. Pronotum in lateral view strongly convex, outline with anterior constriction, without posterior constriction ( Figures 10 View FIGURES 1–11. 1–5 , 97 View FIGURES 92–99. 92–99 ), in dorsal view with sides slightly divergent from base to midlength, then convergent to apex, constricted beyond middle; disc somewhat hollowed medially, punctures dense to contiguous at base and progressively more widely spaced, smaller and shallower to apex ( Figures 14 View FIGURES 12–19. 12 , 96 View FIGURES 92–99. 92–99 ); surface granulate. Elytra with tubercles as follows: I2 with round and large tubercle at declivity base; I3 with two tubercles, first subbasal, second smaller, round at middle of elytra; I4 with laminate tubercle beyond declivity; I5 with two small tubercles in same position as tubercles on I3; I7 with two tubercles in same position as tubercles on I5. Metasternum moderately concave, median section glabrous. Male abdomen with ventrite 1 moderately concave, squamous; ventrite 2 feebly concave, longer than ventrites 3–4 combined, squamous; ventrite 5 flat, without impressions, as long as ventrites 1–2. Femora armed, hind femur reaching elytral apex, tibiae with inner margin slightly sinuate, premucro present. Male genitalia ( Figure 129 View FIGURES 120–129 ) with median lobe in lateral view weakly curved, slender; in ventral view as long as apodemes, lateral sides moderately swollen at 0.25 length from the base, convergent, apex acute; apical process in lateral view moderately large (0.26–0.34 as long as body of median lobe), straight, moderately curved downward; in ventral view not constricted beyond median orifice, lateral sides convergent.
