Diagnosis. Members of the species-group are characterized by the forewing with only a medial black line and lengthwise strokes along veins in the postmedial area, whereas in most members of the A. aberrans species-group the antemedial, medial and postmedial transverse lines are present and together form the “miltochristoid” pattern. In the male genitalia capsule, the distal saccular process is short, robust and apically blunt, whereas in A. aberrans species-group, the distal saccular process is longer, narrower and apically pointed (Singh et al., 2021).

Morphology. Adults. Length of forewing 12–13 mm in males and 14 mm in females. Antennae pale pinkish in basal third and gradually darkened to black in distal two thirds. Head and thorax pinkish, abdomen covered by blackish hair-like scales mostly, with only the basal section covered by pinkish hair-like scales. Forewing ground color deep pinkish to brick red, suffused with blackish scales in certain species. Forewing pattern black, consisting of a straight medial line and several lengthwise strokes along veins. Hindwing generally pinkish, apex suffused with black scales. Male genitalia. Uncus long and slender, with a small claw-like tip. Tegumen long and narrow. Vinculum narrow. Saccus U-shaped. Juxta shield-like. Valva moderately long and broad. Costa broad and heavily sclerotized, with a rounded medial dorsal protrusion and a distal costal process of different length. Sacculus broad and strongly sclerotized, with a stout and blunt distal saccular process. Distal membranous lobe elliptical. Aedeagus slender, vesica broad and sack-like, consisting of several small diverticula and two clusters of cornuti. Female genitalia. Papilla analis rectangular, broad and short. Apophyses posteriores somewhat longer and narrower than apophyses anteriores. Ostium bursae narrow. Ductus bursae strongly sclerotized and long. Corpus bursae elliptical, covered with numerous spinules and bearing small and rounded signum. Appendix bursae long, equal in length to corpus bursae, moderately sclerotized, covered with numerous spinules basally and medially.
