Material examined. Holotype ♂, Indien, Rajasthan, 2 km n Ajmer, 26°28'N, 74°38'E, 400 m, 28.xi.1992 (Hacker & Peks) (gen. slide 539/14, O. Bidzilya) (coll. G. Derra). Paratypes: 1♂, 1♀, Indien, Rajasthan, 1 km ö Puschkar, Forest Garden, 26°29'N, 74°33'E, 400 m, 29.xi.1992 (Hacker & Peks) (gen. slide 545/14♀, 556/ 14♂) (all coll. G. Derra).

Description. Adult ( Figs. 15, 16 ). Wingspan 12.0 mm (male), 14.6 mm (female). Head: Light brown, segment 2 of labial palpus white with rare black scales at base and near apex, particularly on underside, inner surface white; segment 3 white mottled with brown, twice narrower and about as long as segment 2, acute; antenna in male slightly thicker than in female, scape brown with white apex, others antennal segments brown in male and brown with white basal rings by female. Thorax: Dorsum and tegulae brown to black; forewing covered with brown black-tipped scales, costal margin mottled with black, two black spots at base, diffuse black spot in middle at ¼ length, indistinct black streak in fold, subtriangular black spot at ¾ of costal margin, apex of wing uniformly brown without black scales, separated by poorly expressed whitish spots at dorsal and costal margin; cilia brow blacktipped; hindwing light grey. Variation. Forewing of both males are coloured more uniformly, black subtriangular spot at ¾ of costal margin poorer expressed. Abdomen: Male genitalia ( Fig. 25 ) with uncus short, rounded, densely covered with strong long setae; gnathos very long, weakly curved, broadened at ¾ length, apex narrow, pointed; tegumen sub-triangular, gradually narrowed distally, anterior margin with broadly rounded emargination; valva long, extending far over the top of uncus, distal portion densely haired, narrow at base, inner margin gradually broadened after short triangular tooth at 1/3 length, apex rounded; sacculus broadly rounded at base, distal part very narrow, about 1/3 length of valva; vincular lobes divided posteriorly into long and narrow lateral and short sub-triangular medial projections, anteromedial incision deep, very narrow; saccus short, broadly rounded; phallus swollen at base, distal portion narrow, apex weakly broadened, rounded, with one long lateral arm. Female genitalia ( Fig. 32 ) with papillae anales subovate, covered with short setae, segment VIII subrectangular, evenly sclerotized except for elongate patches extending posteriorly from base of apophyses anteriores, posterior margin straight, anterior margin broadly emarginated, with strongly sclerotized narrow patches joint in middle; apophyses posteriores very long and narrow, apophyses anteriores narrow, straight, slightly longer than segment VIII; antrum broad, rounded, ductus bursae of even width, posterior portion weakly broadened, covered with fine spines, with gradual transition to corpus bursae that is the same width with ductus bursae; signum absent.

Remarks. A. indicus resembles externally A. kuehnei , but black pattern along the costal margin is weakly expressed. The genitalia of both sexes resemble those of A. hackeri but the tooth on the inner margin of the valva is smaller, the valva is longer, the lateral projection on the lobe of the posterior margin of the vinculum is longer and narrower, the anteromedial incision is narrower, the apex of the phallus is with one arm rather than two in the male. The female genitalia differ from those of A. hackeri in that the ductus bursae is shorter, not narrowed distally, and the anterior margin of the segment VIII lacks the triangular projections.

Biology. Adults have been collected in late November at an elevation of 400 m.

Distribution. India (Rajasthan).

Etymology. The specific name refers to the distribution of the new species.
