Systematics: Wang (2001) separates A. atratus from A. yunnanensis in his key by the presence of 8-shaped pores with three lateral closed pores (“trilocular”) in the latter species but these are absent in A. atratus.
Structure: Based on the figure in Wang (1980), the adult female of A. atratus is characterised by the following combination of character-states: (i) eight-shaped pores on dorsum restricted to three or four transverse bands across abdominal segments; (ii) cribriform plates absent; (iii) tubular ducts on dorsum of one size, sparse medially becoming more abundant around margins; (iv) tubular ducts on venter absent medially; (v) posterior stigmatic bands bifurcated; (vi) stigmatic bands each with very few spiracular disc-pores near spiracles, broadening near margin; (vii) 8-shaped pores of two sizes on venter, smaller forming a marginal band and larger randomly distributed within apex of each stigmatic band; (viii) multilocular disc-pores present across abdominal segments II–VII, and probably on metathorax (also perhaps very sparsely medially on thorax); (ix) leg stubs present, and (x) loculate pores near antennae few.
