Frontal prominence much longer than wide at its base. Face with very short paraface, and small anterior tentorial pit. Face with a more or less conspicuous tubercle. Eye bare. Pile on thorax and tergites short. Basisternum ( Fig. 53 ) rectangular and narrow, with straight dorsal margin and ventral margin with two large triangular extensions. Anepisternum and anepimeron fused. Procoxa ( Figs 49, 50 ) broad, about as wide as long, with a clearly demarcated groove on its entire length dorsally. Postmetacoxal bridge incomplete. Dorsal lobe of calypter with a fringe of short and sparse pile. Abdomen elongate and only slightly petiolate. Callus of tergite I clearly demarcated, large and yellow. Callus of sternite I strongly sclerotized and large, black to yellow. Posterior margin of tergites elevated in lateral view. Tergite VIII white pilose. Genitalia ( Figs 56–63 , 71–82 , 87–89 , 94–97 , 102–113 ): Dorsal lobe of surstylus elongate with narrow shaft and broadly rounded apex, ventro-basal lobe rounded; dorsal lobe of surstylus with short setae along its apical margin and medially; epandrium round, with large membranous part ventrally; cercus short and broadly triangular, simple; surstylar apodeme fused, oval hyperboloid formed and entirely but slightly sclerotized; hypandrium elongate with simple superior lobe and lingula ( Figs 56 , 59, 62 , 76, 81 ) or with triangular superior lobe with long and extended ctenidion along posteroventral margin and with an elongated and often bi- or tridentate lingula ( Figs 71, 74 , 87, 89 , 94, 95 , 102, 103 , 106, 108 ).
