9(8). Area above and behind antenno-ocular carina of head ( Fig. 11 , arrow) with one or several distinct minor carinae formed by confluent punctures (e.g., Figs. 11–13 , 58, 60–62 ); medial pronotal seta ( Fig. 23 , mse) adjacent or much closer to lateral than to medial sulcus.......... (18) A. ecarinatus

9′(8). Area above and behind antenno-ocular carina of head ( Fig. 11 , arrow) smooth (e.g., Fig. 59 ), without distinct carinae (except for possibly distinct sublongitudinal ridge – Fig. 10 , sr; e.g., Figs. 10 , 59 ); medial pronotal seta ( Fig. 23 , mse) subequidistant from medial and lateral sulci ( Figs. 73–74 )..............................10

10(9′). Sublongitudinal ridge of head present and distinct ( Fig. 60 , sr); dorsal tentorial sulcus distinctly slit-like, or very narrowly ovate ( Fig. 60 , dt); apical labral margin in males without pair of enlarged contiguous teeth at middle, or with two enlarged, separated teeth ( Fig. 147 )....12

10′(9′). Sublongitudinal ridge of head absent, or difficult to distinguish from other ridges or carinae (similar to Figs. 11 , 61–62 ); dorsal tentorial sulcus not distinctly slit-like; broadly to very broadly ovate; apical labral margin in males with pair of enlarged contiguous teeth at middle ( Figs. 171, 174 ) .................................. 11
