Diagnostic description
Holotype, male (Fig. 79a). Length 2.46 mm. Color of antennae and legs ferruginous; remainder black. Body in dorsal aspect subovate, with marked constriction between pronotum and elytron; in profile dorsally flattened, apex convex. Rostrum in basal half with median and pair of submedian ridges becoming indistinct apically; intervening furrows each with row of coarse punctures and suberect piliform scales; epistome with indistinct, transverse ridge. Pronotum with sides subparallel, anteriorly with distinct subapical constriction; disk coarsely punctate, reticulate; with indistinct median ridge; sparsely setose with minute setae. Elytra with striae distinct; intervals flat, each with row of small punctures; subbasally punctures more dense and confused; each puncture containing small recumbent scale. Profemur with anteroventral ridge indistinct; meso- and metafemur anteroventrally serrate, bearing row of large sharp teeth, in apical 1/3 simple. Metafemur subapically with stridulatory patch. Dorsal edge of tibia subbasally with angulation, in mesotibia with distinct tooth. Abdominal ventrite 5 flat, coarsely punctate. Penis (Fig. 79b) with sides converging to subangulate, denticulate apex; in profile body bent ventrad at right angle; transfer apparatus flagelliform, 2.0 × longer than body; apodemes 2.0 × as long as body; ductus ejaculatorius with bulbus.
