Diagnosis. The new species, A. albicans sp. nov. (Figs. 7, 8), is similar to A. infausta (Fig. 11) and A. obscura (Fig. 12) in the general coloration and pattern of the forewing, particularly in the presence of dark grey ground coloration, a darker area near the reniform, a slightly curved, darker, and zigzag postmedial line. Externally, it differs clearly from A. infausta (Fig. 11) and A. obscura (Fig. 12) by the more contrasting dark elements of the wing pattern and the ochre-yellowish coloration of the inner part of the hindwings. In the structure of male genitalia, A. albicans sp. nov. (Fig. 16) differs from A. infausta (Fig. 19) and A. obscura (Fig. 20) by the shape of the valva, the shape of the aedeagus, and the position and size of the basal cornuti field of the vesica.
Description. Adult (Figs. 7, 8). Forewing length— 19–21mm in males. Holotype — 20mm. Head, thorax black scales, black tegulae. Palpi short, blackish gray, gray irrorated.Antennae long.Abdomen black, brown, gray irrorated scales. Forewing warm gray with brown tints. Subbasal line black. Antemedial line double, black, straight, costa to dorsum. Postmedial line double, black, incurved below vein 4, continuous to dorsum. Reniform stigmata kidney-shaped, lighter, encircled with black. Orbicular stigmata brown-gray, black outline, connected by black streak. Subterminal area lighter, defined by black dentate marks, angled at veins 7, 6, excurved at middle. Terminal line thin yellowish outline. Cilia mottled. Hindwing cream in basal 2/3, greyish-brown terminal band, cilia greyish-brown, black opposite veins. Male genitalia (Fig. 16). Uncus massive, straight, wide at base, narrower at apex. Tegumen with two short sclerotized penicular extensions, shorter than vinculum. Vinculum V-shaped. Juxta hexagonal, shieldlike. Valva large, lobe-like, constricted distally, narrower at apex. Sacculus robust, thin hairs. Saccular process sclerotized, thin, curved, distal half of valva, extends slightly beyond apex. Aedeagus large, massive, thicker at apex, straight. Carina crescent-shaped, highly sclerotized. Vesica large, ventrally everted, with basal, medial, apical diverticula covered in pin-like cornuti.
Female unknown
Genetic information (Fig. 21). Seven specimens including holotype of A. albicans sp. nov. has been sequenced and two of the sequences (holotype and one paratype) has been assigned the BIN BOLD:AFD4683. The intraspecific divergence ranges between 0.00–1.21%. The nearest neighbor of the species is the unidentified Anacronicta sp. (BIN BOLD: AAN7313) from Pakistan (MAMOT556-10| Anacronicta |COI-5P| HQ991245 and MAMOT2258- 12| Anacronicta |COI-5P| KX862581) with pairwise distances in the range of 1.75%.
Etymology. The specific name is originated from Latin word “ albicans ” meaning “light yellowish white” colour of the hindwing upperside.
Distribution. India — Manipur.
