3.1.3 Bacchisa atritarsis (Pic, 1912) ( Figs 3C , 5A , 6A, 7A)

Tegmen about 4.0 times as long as wide, slightly curved; lateral lobes short, about 1/9–1/10 times as long as tegmen, cylindrical, about 2.2–2.3 times as long as wide; apex transparent; with dense long hairs at middle; roof short, about 0.7–0.8 times as long as lateral lobes; apex dehiscent; ringed part converging at apex, apex flat. Median lobe plus median

© Zoological Systematics, 40(2): 197–211 struts slightly curved, about 5.8 times as long as wide; median lobes 3.4 times as long as median struts; dorsal plate significantly shorter than ventral plate, apex sharp-pointed. Internal sac with rod at apex, rod longer than median lobe plus median struts and slender. 8th abdominal tergaum sub-square, 0.9 times as long as wide; apex slightly concave, with dense long setae on lateral sides; 8th abdominal sternum about as long as but slightly narrower than dorsal plate; apex flat, with dense long setae on lateral sides; spiculum gastrale long, about 1.8 times as long as tergaum.
