Description

Male labroclypeus ( Fig. 139 View Figs 133–144 ) deeply emarginate, anterolateral angles protruding. Female labroclypeus ( Fig. 140 View Figs 133–144 ) with obtuse and less protruding anterolateral angles. Lateral margins of labroclypeus strongly sinuous in both dorsal and lateral views. Anterolateral angles raised up at angle of nearly 70-80° to frons in lateral view. Anterior and lateral margins of labroclypeus smooth. Upper- and underside of labroclypeus with sparse very long setae along anterior and lateral margins. Canthus broadly rounded in dorsal view. Head dorsal punctures circular, in part annular. Intervening spaces glossy, variably large. Head setae scale-like, elongate; each seta rises from anterior margin of corresponding puncture. Antenna 7-segmented, club 3-lamellate. Anterior margin of pronotum subtruncate with protruding anterolateral angles, basal margin broadly rounded. Lateral margin of pronotum broadly rounded, delicately crenulate all along ( Fig. 227 View Figs 226–241 ). Extraordinarily long erect distally curved seta present between every two crenulae. Lateral margin of pronotum nearly straight in lateral view. Pronotal punctures annular, variable in size. Intervening spaces glossy, variably large. Pronotal setae rather large, suberect, rising from anterior margin of corresponding punctures. Hypomeron separated from prosternum by straight vague carina, with moderately long setae on its anterolateral margin opposite to compound eye ( Fig. 272 View Figs 266–277 ). Antennal pocket shallow. Elytron subopaque, surface delicately wrinkled. Punctures of elytral disc double ( Fig. 318 View Figs 317–332 ). Ordinary punctures of irregular shape, shallow, dense. On background of each ordinary puncture with additional linear (long and narrow), incision-shaped puncture. Intervening spaces glossy, much larger than incisions. Elytral setae of variable length, not surpassing to strongly surpassing length of corresponding incisions. Pygidium in both sexes slightly convex dorsally, with large dense and shallow annular punctures and moderately long erect setae ( Fig. 487 View Figs487–503 ). Protibia is modified also on inner margin, concave predistally. Male and female protibia distally tridentate on external margin (Fig. 391). Female metatibial terminal spurs short, unequal in length, rounded apically, male one longer, subequal in length and nearly pointed. Spiculum gastrale as in Fig. 569 View Figs 545–569 . Aedeagus as in Figs 649–651 View Figs 632–651 .
