Head clothed with light brown scales, punctures similar to punctures on rostrum; vertex with whitish scales, dense to contiguous, uniformly distributed along vertex; frons concave, rostrum moderately robust, moderately carinate, apical area puncticulate; eyes moderately concave. Pronotum in lateral view moderately convex, outline with anterior constriction, without posterior constriction ( Figures 10 , 95 ); in dorsal view with sides slightly divergent from base to midlength, then convergent to apex, constricted beyond middle; disc with longitudinal impression, surface with dense and deep punctures on flanks, becoming smaller, scattered towards the middle, weakly carinate, disc clothed with whitish scales, dense on lateral sides and flanks, anterior area forming a thick longitudinal fringe along middle and narrow strip that diverges from middle base to flanks, and with dark brown or black scales on middle and posterior areas of disc ( Figures 14 , 94 ). Elytra strongly convex, with basal margin slightly sinuate ( Figure 3 ); tubercles as follows: I2 with small and round tubercle on declivity base (absent in one specimen), I3 with two tubercles, first tubercle subbasal, second tubercle at middle of elytral declivity, I4 with two small tubercles, first tubercle between tubercles on I3, other tubercle at base of elytral declivity, longer than tubercle on I2, I5 with two small tubercles in same position as tubercles on I3, I6 with very small tubercle between tubercles on I5. Metasternum moderately concave, glabrous, metasternal tooth present. Abdomen with ventrites 3–5 not in same plane as ventrites 1–2, ventrite 1, moderately concave, glabrous in median section, ventrite 2 feebly concave, as long as 3–4 combined, with a transverse line of scales along middle, ventrite 5 convex along median line, as long as ventrite 1, with anterior impression. Femora armed, hind femora length not reaching elytral apex, tibiae subparallel, front tibiae with inner margin sinuate, premucro absent. Male genitalia ( Figure 128 ) with median lobe in lateral view moderately curved, moderately stout; in ventral view as long as half of apodeme length, lateral sides straight, apex acute; apical process in lateral view small (0.17–0.25 as long as body of median lobe), sinuate, moderately curved downward; in ventral view constricted beyond median orifice, sides convergent. Female genitalia with tergite eight trapezoidal, apex invaginate, smooth, sternite eight doliform, median membranous area 2/3 as long as basal plate, spermatheca shallowly curved, outer margin not convex, ramus long and slender, nodulus slender.
