sp. n.), with which it most likely shares a recent common ancestor. It is a dark-brown species without metallic luster with a strongly reduced third dorsal elytral stria. It differs from the other two species chiefly by almost completely impunctate pronotum (punctate in the other two species) and different male terminalia. Its eighth sternite is strongly sclerotized and narrowing apically (Fig. 382), whereas the eighth sternite of other two species is not so strongly sclerotized and wider apically. Likewise, the eighth sternite of

Pronotal sides (Fig. 372) moderately narrowing apically, pronotum except for a double row of sparse punctures along pronotal base glabrous (other two species have a band of punctures along lateral margins; compare Figs 422 and 511). Elytral structure as well as configuration of elytral striae generally similar between the three species (compare Figs 372, 422 and 511), with characteristically shortened third elytral stria. Elytral punctation confined to apical elytral third, elytral flanks impunctate, punctures rather deep, forming strioles, interspaces without microsculpture, punctures separated by about their own diameter (Fig. 372).

Male genitalia. Eighth sternite (Figs 382-383) apically with several pseudo-pores, entirely fused, strongly sclerotized, fused sternite basally with median projection among otherwise widely separated halves; apex of eighth sternite laterally with two tufts of several moderately long setae; eighth tergite and eighth sternite fused laterally (Fig. 384). Ninth tergite (Figs 385-386) typical for the subfamily; anterior margin of tenth tergite straight; spiculum gastrale (Fig. 385) gradually dilated on apical half; apical end strongly sclerotized; basal end abruptly dilated, almost heart-shaped. Aedeagus (Figs 387-388) slightly gradually dilated from base towards apex, but before apex slightly constricted; parameres fused along their basal half (roughly); basal piece of aedeagus short, ratio of its length: length of parameres 1: 6; aedeagus almost straight, only apically slightly curved from lateral view (Fig. 388).
