( Figs. 11 , 32 , 51, 51 a, 64)

Holotype: ♂, CAMBODIA, Cardamom, 11o35′04″ N 103o13′ 20″E, 22 xi 2012 (YS Bae et al.), gen slide no. CIS- 6439. Paratype: 2♀, CAMBODIA, O’som, 12o01′75″ N 103o11′ 21″E, 21 ii 2012 (YS Bae et al.), gen slide no. CIS- 6451.

Diagnosis. This new species is superficially similar to the preceding new species, A. gryphodes , but it can be distinguished from the latter by the smaller size and the anterior expansion on costa extended to 2/3 and a row of pectens along Sc vein on under side in the hindwing. The male genitalia can be distinguished by having longer uncus, extremely small socii, left valva with a very long thread-like basal process and a characteristic digitate long process on anterior margin beyond middle. The male genitalia resemble those of A. ephippias Meyrick, 1908 which was described from India, but are distinguished by having a long, digitate process on the anterior margin.

Description. Adult: Male ( Figs. 11 , 32 ): Wingspan, 10.5–12.5 mm. Head creamy to orange white. Flagellum of antenna with indistinct brownish annulations. Second segment of labial palpus in male ( Fig. 29 ) subquadrate, with scale tuft antero-ventrally, densely covered with blackish scales on outer surface, with creamy white scales along upper margin, orange white on inner surface. Tegula same in color as dorsal surface of head, with blackish scales along anterior margin. Thorax same in color as dorsal surface of head. Hind tibia slender, orange whitish, speckled with blackish scales on outer surface, with blackish hair-like scales dorsally. Forewing elongate; ground color grayish white, mottled with brownish scales; costa slightly convex medially, no blackish streak at base; costal patch rather small, subtriangular, occupying about 1/8 of costa and reaching 1/4 the distance across wing, with two small dark brownish marks before and beyond costal patch respectively; a blackish oblique streak beyond middle of cell well-developed, with a long whitish hair pencil near base on the underside of the forewing; apex more or less obtuse; termen oblique; fringe concolorous with ground color of wing. Hindwing grayish white, hyaline, with brownish scales along veins; broad anterior expansion on costa extended to middle, gently oblique, and with a row of pectins along Sc vein on under side; apex more or less acute.

Male genitalia ( Figs. 51, 51 a): Abdominal sternite VIII rounded on caudal margin. Uncus stout; socius fanshaped, large, width more than four times of median process of uncus. Tegumen relatively narrow, dilated at middle, narrowed towards apex. Left valva large, semiovate, with a very long thread-like, coiled, basal process, about 1.5 times longer than valva, and with a characteristic, long, digitate process on dorsal margin beyond middle; patch of modified scales in distal 1/6. Right valva nearly parallel sided; patch of modified scales as in left valva. Phallus taenioid, tapered, as long as left valva.

Female genitalia ( Figs. 64 ): Abdominal tergite VII with a small crescent membranous flap medially. Apophyses anteriores short, about 1/3 the length of apophyses posteriores. Ostium bursae deeply concave on caudal margin. Ductus bursae narrow, as long as corpus bursae, narrowed in anterior 1/4; ductus seminalis narrow, arising from near junction with corpus bursae. Corpus bursae oblong, with dense, minute spicules on internal surface; signum forming a long transverse ridge with triangular plate beneath, located medially.

Distribution. Cambodia (Cardamom, O’som).

Etymology. The species name is derived from the Latin, camp (= various) with the Latin suffix estris, meaning “living in.
