Holotype, male (Fig. 50a). Length 2.97 mm. Color of legs and antennae ferruginous; pronotum and elytron reddish coppery; remainder dark ferruginous to black. Body in dorsal aspect with marked constriction between pronotum and elytron; in profile with weak constriction. Rostrum with median and pair of indistinct submedian ridges; intervening furrows each with row of coarse punctures and suberect elongate scales; epistome with indistinct transverse ridge forming small median denticle. Pronotum with sides subparallel; anteriorly rounded to subapical constriction; disk coarsely punctate, reticulate; with sparse recumbent, elongate, cream-colored scales, especially anteriorly; medially swollen, with median ridge. Elytra with humeri markedly swollen, laterally projecting; striae distinct, basally deeply impressed; intervals weakly costate, punctate; sutural interval in basal half distinctly swollen; punctures near base coarse and dense, near middle sparser with interspaces polished; each puncture containing minute, inconspicuous seta. Profemur with anteroventral ridge indistinct; in meso- and metafemur forming large, acute tooth. Metafemur subapically with stridulatory patch. Dorsal tibial edge subbasally with angulation. Thoracic and abdominal venter setose with long erect setae. Abdominal ventrite 5 weakly concave, densely punctate-rugose, with dense erect setae. Penis (Fig. 50b) subapically converging, with pair of setose brushes; subtruncate at middle; transfer apparatus small, compact; apodemes 2.7 × as long as body; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.20–2.97 mm. Color of pronotum and elytron ranging from dark bronze to a more vivid coppery. Female body more slender, humeri less prominent. Female rostrum dorsally punctate-rugose, with median and pair of submedian subglabrous costae; epistome simple.
