Remarks. The new species is similar to A. (A.) hamaculeata sp. nov., but differs in the following characteristics: abdominal apodemes extending to base of 6th abdominal sternite ( Fig. 98 View FIGURES 98–105 ); pygofer process with some rigid setae ( Fig. 100 View FIGURES 98–105 ); style with subapical process forming an obtuse angle with apical part ( Fig. 103 View FIGURES 98–105 ).
Etymology. This specific epithet is derived from Latin words “niger” and “flavus”, referring to the overall black and yellow coloration ( Figs 21, 22 View FIGURES 17–32 ).
