Description
Dorsum and venter covered with microscopical velvety pubescence. Male labroclypeus ( Fig. 179 View Figs 169–180 ) broadly rounded on anterior margin, its anterolateral angles acute and protruding. Female labroclypeus ( Fig. 180 View Figs 169–180 ) with less acute anterolateral angles. Head punctures ovoid, rather deep and dense. Head setae scale-like, dense, suberect, moderately long, in part clavate. Some setae not surpassing length of corresponding punctures. Pronotum broadly emarginate on anterior margin with protruding anterolateral angles. Basal margin of pronotum slightly sinuous. Lateral margin of pronotum in dorsal view very broadly rounded in anterior half, shallowly emarginate postmedially towards base ( Fig. 256 View Figs 242–258 ). Hypomeron slightly emarginate and long setose on anterior margin which is flange-like protruding, shallowly emarginate and long setose opposite compound eye ( Fig. 281 View Figs 278–285 ). Antennal pocket deep. Pronotal punctures of irregular oblong shape, deep, intervening spaces generally larger than punctures. Pronotal setae scale-like, dense, suberect, in part minute and not surpassing length of corresponding punctures, in part (in particular, along lateral margins and on anterior margin opposing frons) long and clavate. Elytral punctures irregular in shape, deep, somewhat irregularly clustered ( Fig. 346 View Figs 333–348 ) and generally smaller than those on pronotum. Setae between puncture clusters longer, scale-like, stronger erect, arranged in several irregular longitudinal rows. Setae in puncture clusters minute, not surpassing length of corresponding punctures. Male and female pygidium with deep irregularly shaped punctures. Intervening spaces glossy, variably large. Male pygidium with two flat latero-median humps (humps very inconspicuous in some specimens), with group of large long dense scale-like setae (can be strongly reduced in some specimens) pointing obliquely to middle or posteriad ( Figs 519–520 View Figs 504–521 ). Female pygidium with two latero-median humps and transverse row of long scale-like whitish setae pointing obliquely medially ( Fig. 521 View Figs 504–521 ). Male and female protibia with two rather acute terminal teeth on external margin (Fig. 418). Male terminal protibial spur curved, female one straight and pointed. Spiculum gastrale as in Fig. 562 View Figs 545–569 . Male aedeagus as in Figs 718–720 View Figs 712–725 .
Sexual dimorphism
Lamellae of female antennal club shorter; apex of female elytron with conspicuous, long and rather acutely protruding in this species; female pygidium with a glossy flat median longitudinal area between two latero-median humps.
