Holotype, male (Fig. 80a). Length 3.06 mm. Color ferruginous, sides of elytra black. Body elongate; in dorsal aspect with marked constriction between pronotum and elytron; with distinct constriction in profile. Rostrum with median carina terminating abruptly on forehead; with pair of submedian ridges; intervening furrows each with row of erect, piliform scales; epistome at middle with minute denticle. Pronotum with distinct subapical constriction; disk densely punctate, interspaces partly rugose; punctures each with one piliform scale, in apical half these scales long, suberect. Elytra with striae deeply impressed, each with row of suberect piliform scales; intervals carinate, nude; intervals 2 and 4 basally flat; interval 7 swollen subapically, laterally weakly projecting; sutural interval at apex slightly protruding. Meso- and metafemur with crenulate anteroventral ridge terminating with blunt tooth. Metafemur subapically with stridulatory patch and transverse row of denticles.
