Cercus small, cordiform in ventral view with some short setulae. Gonites arranged in a row; postgonite long with some sensory setulae, distally pointed and slightly incurved; pregonite short, 0.7x as long as postgonite, basally broad; basiphallus cylindrical; distiphallus projected beyond ventral margin of hypandrium, largely membranous; phallapodeme long, extended near base of basiphallus, with basal stalk broad in lateral view.

Distribution. China (Yunnan).

Remarks. A. sinensis is somewhat similar to A. femorata Cherian in having the frontal triangle smooth with a longitudinal groove along each lateral margin and broad median groove; arista with short pubescence; all femora and tibiae black. It can be separated from the latter by the following features: antenna black except for yellow basoventral portion of first flagellomere; second sector of costa 2x as long as third sector; abdomen brown except for pale yellow tergites 1+2 with brown lateral portion, tergite 2 with small black lateral spot. In A. femorata , pedicel is brownish black and first flagellomere is yellowish to dark brown with dark tinge in distal 1/2; second sector of costa is 1.3x as long as third sector; abdomen is entirely black ( Cherian 1984).
