Male diagnosis. Only representative of the genus in Asia, typical of the group lumped formerly under A. panorpoides by the (a) extensively white labrum, labium, thorax and underside of S3–7; (b) low number of Fw Ax, typically 7 but varies between 6 and 8; (c) 1 cell in Fw triangle, but 2 cells in 6% of examined wings; (d) fairly long Fw Pt, about 11–14% as long as Hw; (e) abdomen that narrows abruptly on S 5 in lateral view, with S6–10 slender ( Fig. 7 View FIGURE 7. S 2 – 10 C); (f) fragmented and frayed white markings on S2–5 and large white lateral spots on S7 ( Fig. 7 View FIGURE 7. S 2 – 10 C); and (g) broad and triangular lobe of hamule ( Fig. 8 View FIGURE 8 C). Within this group has the (1) stoutest abdomen, with S6 between 1x and 2x as long as high and a distinct ‘step’ between the ventral borders of S5 and S6 ( Fig. 7 View FIGURE 7. S 2 – 10 C). Latter recalls A. attenboroughi sp. nov. that also only shares the (2) rather slender hook of the hamule ( Fig. 8 View FIGURE 8 C); and (3) sublateral black marking concentrated on apical side of S4 ( Fig. 7 View FIGURE 7. S 2 – 10 C); but differs by the (4) totally black ventro-apical carina of S4, although this is partly white in about 15% of cases ( Fig. 7 View FIGURE 7. S 2 – 10 C). Aside from distribution, unique within the genus by the (5) narrow black band across the antefrons, which is only 10–40% as wide as labrum is high ( Fig. 4 View FIGURE 4 C–D); (6) labrum with no black or only a very small spot that is typically separated from the base ( Fig. 4 View FIGURE 4 C–D); and (7) complete distal Ax in 62% of examined Fw.
