Diagnosis. The new species resembles D. irrorata in appearance, but can be easily distinguished from latter by the forewing white at upper side, its underside dark grey in male, light grey in female; valve approximately rectangular, without projection; aedeagus with a well-developed cornutus; corpus bursae with a smaller signum.

Description. Adult. Forewing length: 12–13 mm in male, 17 mm in female. Vertex covered with white tufts. Antenna bipectinate, white, about 1/3 as long as forewing. Labial palpus porrect, male mixed with white, yellow and black scales, female with pure white scales. A reduced proboscis present. White scales forming a layer over thorax and tegula with white piliform scales. Upper side: forewing with snow-like ground color, basal area scattered with grey dots, a grey oblique band from 2/3 of the inner margin to apex, and a short one from 1/3 of inner margin to CuA 2, apex with yellow scales in male, fringe scales white; hindwing white. Underside: male forewing dark grey, costal margin black at basal half, pale yellow at apical half; female forewing light grey, costal margin white; hindwing white, with a dark dot at the end of discal cell. Wing venation: forewing with M 1 arising from upper angle of discal cell, M 2 separated from M 3, CuA 1 and CuA 2 almost parallel; hindwing with Rs shortly stalked with M 1, M 2 and M 3 arising from under angle of discal cell, respectively. Legs densely covered with white hairs, except the basal part of foreleg mixed with yellow scales, hind leg with two pairs of white spurs on tibia.

Male genitalia. Uncus bifid, the distance between two processes relatively narrow. Gnathos nearly triangular. Valvae simple, approximately rectangular. Juxta well-developed. Tegumen broad. Saccus short. Aedeagus inflated basally, somewhat curved, apically with a ball-shaped vesica and a large cornutus.

Female genitalia. Anal papillae small. Anterior apophysis longer than posterior apophysis; ostium round; ductus bursae shorter than corpus bursa, sclerotized;corpus bursa nearly oval, membranous, with an approximate semi-oval signum.

Paratype. 2♂, 1♀, same data as holotype ; 1♂, Xiaozhongdian , Xianggelila, Diqing, Yunnan, China, altitude of 3180 m, 9. VII. 2013, leg. M. Wang.

Distribution. China (Yunnan).

Etymology. The species name is derived from the Latin “nivis” and “ala”, referring to the wing upperside with snow-like ground color.
