Redescription.

Adult (Figs 9 , 10 ). Forewing length 9-11 mm, wingspan 19-23 mm in male; 12 mm and 25 mm in female of two individuals. Head covered by dark brown scales; labial palpus up-curved, dark brown; antenna filiform. Thorax mainly dark brown mixed with black scales; tegula dark brown. Forewing elongated; ground colour ochreous mixed with dark brown; subapical mark nearly triangle, pale brown, embedded with dark brown patch in medial part; apex dark; forewing with an elliptical ochreous spot located between bases of vines M3 and Cu1A; an ochreous oblique line runs from middle of costal to inner margin at ca 1/3 distance from wing base; and an ochreous, zig-zag line along with outer margin from vines R5 to 1A+2A. Fringe black. Hindwing greyish brown; fringe brown. Fore and mid legs black to dark brown, except tarsus pale brown with long black scales; hindleg pale brown, tarsus same as the former legs. Tibial spurs 0-2-4. Abdomen dark brown to brown, thin and long in male, short and thick in female; sternite VIII with a pair of long and strongly sclerotized piliform processes in male (Fig. 21 ).

Male genitalia (Fig. 22 ). Uncus broad with a papilla in apex. Gnathos sickle-shaped, upper half strongly sclerotized, widened apically. Tegumen short and broad. Valva elongated; base of sacculus slightly inflated, with a large sickle-shaped sacculus process located at margin ca 2/3 distance from the base; cucullus slightly narrower, rounded apically, densely covered with hairs. Juxta with a pair of slender, unequal in length, crescent-shaped lateral processes, the right one is a little longer than the left. Saccus broad, tongue-shaped. Aedeagus slender, sinuous.

Female genitalia (Fig. 23 ). Papillae anales small, flattened, densely covered with short setae. Anterior and posterior apophyses nearly equal in length and both blunt apically. Antevaginal plate sclerotized, with distinctly crumpled surface. Upper part of ductus bursae strongly sclerotized, straight and tube-shaped firstly, then twisted ribbon-shaped, and medial and posterior portions spiral-shaped and membranous. Corpus bursae oval-shaped, with a medial heart-shaped signum.

Distribution.

China (Xizang: Motuo), India.

Bionomics.

The specimens were collected with a light trap at altitudes of 1840-2200 m a.s.l. in May to June, close to a subtropical evergreen broad-leaved forest with massive shrubs, ferns and patches of grassland growing in the ground cover layer of the forest (Figs 25-27 ).

Remarks.

The genus contains two described species to date since its erected in 1931, but records of the females have been lacking. The female adult and genitalia are described herein for the first time.
