Diagnosis: Neadeloides cinerealis and N. glaucoptera belong to the N. cinerealis species-group, and the former species is distinguished from the latter by the larger wing span and the lighter wing and body colour of the adults. In the male genitalia of N. glaucoptera , the ventral valva margin exhibits a minute spine at the tip of the outermost angle, the ventro-distal edge of the sacculus has a small but distinct outgrowth, the saccus is v-shaped with slightly concave sides, the aedeagus apodeme exhibits an elongated, apical sclerotization, whereas in N. cinerealis , the ventral valva margin is smoothly rounded without any spine, the ventro-distal edge of the sacculus is smooth and not protruding, the saccus is U-shaped with convex sides, the aedeagus apodeme is longer and has two small apical processes of different shapes.

Description. Wing span, Male: 48–50 mm, female 44–46 mm. Adult greyish with silver tinge. Forewing costa slightly fulvous up-to basal half; hindwing whitish, legs white. Male genitalia ( Fig. 8 ) with uncus inverted Ushaped, strongly concave on ventral side, subapical lateral process on both sides, tip with short simple setae; small socii present; tegumen broad; transtilla membranous. Valva elongated flap-like with basal half almost membranous, distal half sclerotized; costa almost straight; ventral margin outwardly angled at middle; distal saccular process hooked, reaching almost centre of the valva; an elongated ridge with a patch of long setae at centre of the inner valva wall. Juxta small with lateral extensions; vinculum and saccus forming a u; aedeagus straight, with a short rounded coecum, apex with two sclerotised processes: one approximately triangular, the other elongated; vesica membranous, field of scobination present, cornuti absent (cornuti in Neadeloides are deciduous in nature so they may be secondarily lost after copulation). Female genitalia ( Fig. 12 ) with corpus bursae globular; a large, rhomboidal signum with two carinae flanking the opposite sides of the centre; no appendix bursae present on corpus bursae or anterior ductus bursae; ductus bursae long, thin, broadening and curled at posterior end, antrum strongly sclerotized, anterior third funnel-like, leading into the broad rectangular posterior antrum part; apophyses anteriores about as long as the signum, apophyses posteriores somewhat shorter.

Distribution: Sikkim, Darjeeling ( India).
