Diagnostic description.

Holotype, male (Fig. 35a). Length 3.66 mm. Color of legs, head and ventral surface ferruginous; pronotum and elytron reddish coppery, partly with slight greenish lustre. Body in dorsal aspect with marked constriction between pronotum and elytron; in profile dorsally convex. Rostrum in apical third scabrous; in basal half with median and pair of submedian ridges; intervening furrows each with row of coarse punctures and suberect piliform scales; epistome with transverse, angulate ridge forming distinct median denticle. Pronotum with sides subparallel; anteriorly abruptly rounded to subapical constriction; disk with pair of submedian impressions, coarsely punctate, reticulate; each puncture containing inconspicuous seta; medially swollen. Elytra with humeri markedly swollen, laterally projecting; interval 4 subbasally swollen, forming dorsal protrusion; interval 5 behind middle weakly swollen, gently projecting from lateral outline; striae distinct; intervals flat, each with row of small punctures; subbasally striae 2-6 deeply incised, intervals and humeral callus densely coarsely punctate; punctures each bearing small inconspicuous scale. Anteroventral ridge of femora distinct, in meso- and metafemur forming large tooth. Metafemur subapically with stridulatory patch. Dorsal edge of pro- and mesotibia subbasally with angulation; meso- and metatibia subapically with dorsal margin concave; mesotibia in apical 1/3 with tooth on dorsal edge. Abdominal ventrite 5 flat, coarsely punctate; with long, suberect setae. Penis (Fig. 35b) with sides of body subparallel; apex subangulate; transfer apparatus small, compact; apodemes 2.0 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.38-3.78 mm. Color of pronotum and elytron ranging from reddish to greenish coppery. Female body more slender. Female rostrum dorsally punctate-rugose, with median and pair of submedian subglabrous costae; epistome simple. Female elytra subovate, without swellings, lateral contour convex, humeri simple.
