Diagnostic description
Holotype, male (Fig. 23a). Length 3.84 mm. Color of antennae ferruginous; basal third of elytra and legs dark ferruginous; remainder black. Body in dorsal aspect with marked constriction between pronotum and elytron; in profile dorsally flat, apically convex. Rostrum with median and pair of submedian ridges; intervening furrows each with sparse row of erect piliform scales; epistome with transverse ridge forming submedian pair of small denticles. Pronotum with sides subparallel, rounded to indistinct subapical constriction; disk densely punctate, reticulate; with indistinct median ridge; with swelling in anterior half. Elytra with striae near base and apex distinct; intervals partly swollen or with coarse punctures each bearing small, suberect, cream-colored scale; transverse band at middle with indistinct striae, intervals subglabrous, sparsely punctate; apex subangulate. Anteroventral ridge of femora forming large tooth. Metafemur subapically with stridulatory patch. Dorsal edge of tibiae with subbasal angulation dentate. Abdominal ventrites 1–2 concave, subglabrous; abdominal ventrite 5 flat, coarsely punctate, with sparse erect piliform scales. Penis (Fig. 23b) with sides of body subparallel; apex bisinuate, with median notch; transfer apparatus compact, symmetrical, but slightly tilted to the left; apodemes 2.5 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 3.04–4.04 mm. Coloration of elytral base ranging from orange-ferruginous to dark ferruginous and almost black. Female rostrum with median and pair of submedian glabrous costae; epistome simple. Female elytra more slender, with lateral contour convex to apex; punctures sparser and smaller than in male; male elytra relatively broad between humeri, converging in almost straight line to apex.
