Thorax – prothoracic collar and thorax white. Foreleg: coxa white with middle brown spot; femur, tibia and tarsus brown with white-ring in middle of tibia and at joints. Middle leg: femur and tibia white with brown rings at femoral-tibia joint and near apex of tibia; tarsus brown, white-ringed at joints. Hindleg: femur and tibia white; first tarsal segment white shading to brown at joint with second segment; remaining tarsi brown, white-ringed at joints. Wings: male (FWL 9.5-11 mm). DFW: ground color dark creamy-white over basal half of wing with pale brown transverse lines; splotchy brown and pale on remainder of wing producing a very mottled aspect; prominent white preapical patch on costa; orbicular spot virtually obsolete, defined only by a few dark scales; reniform spot circular, outlined in back and filled mainly with iridescent blue scales; a prominent dark bar distal to reniform spot; a second reniform-like spot below and proximal to reniform spot irregularly outlined in black and with some blue scales in middle; a brown bar below this spot on inner margin; terminal line an irregular series of dark dashes; fringe a mixture of white, gray, and pale brown scales with pale-colored scales concentrated to form a patch near middle of wing and a smaller patch distal to reniform spot. DHW: luminous white, nearly hyaline, with pale brown marginal band; fringe white. Female (FWL 10.5 mm, 1 specimen) – similar to male. Male genitalia (Fig. 21) – uncus: decurved, long, narrow, tapering to pointed tip. Valve: asymmetrical; right valve roughly rectangular, pointed at apex of dorsal margin; corona well-developed; clasper on ventral margin of right valve, narrower near base than at ventral apex of cucullus where clasper abruptly tapers into a long, curved spine follows outer margin of cucullus almost to apex; dorsal margin of clasper with elongated, triangular process on dorsal margin near base; saccular process smooth, broad, somewhat spatulate apically, lying along dorsal margin of clasper; left valve similar to right valve but saccular extension absent and apical part of clasper with spine-like apical part reduced to short inward hook at ventral apex of valve. Aedeagus: very similar to that of A. toddi except cornutus at base of subbasal diverticulum larger than in A. toddi. Female genitalia (Fig. 27) – ostium bursae funnel-like, tapering only slightly to junction with ductus bursae; lower portion of tubular ductus bursae moderately sclerotized, in length about 0.45 × length of ovoid corpus bursae; spinose pouch of corpus bursae to left of ductus.
