Material examined.
Holotype. ♂, China, Xizang Autonomous Region, Linzhi (= Nyingchi) City , Motuo (= Medog) County , Beibeng Countryside , Dergong Village , 25.V-4.VI.2021, HL. Han leg., genit. prep. WuJ-572-1 (NEFU) . Paratypes. 3♂, China, same data as for holotype, genit. prep. WuJ-573-1, WuJ-556-1, WuJ-557-1 (NEFU) .
Diagnosis.
The new species is extremely similar to the type species F. melkaya (Fig. 12 View Figures 7–14 ) in appearance, only the ground colour of the whole body is paler than the latter. It can be clearly distinguished from the latter by the male genitalia as follows. In F. ravalba sp. nov. (Fig. 25 View Figures 21–28 ), the basal hairy papula on the valva is small, rounded; the juxta lacks a lateral process; the aedeagus bears several strongly sclerotized long spines at the apical part; the vesica contains two peg-like cornuti. However, in F. melkaya (Fig. 26 View Figures 21–28 ), the basal hairy papula of the valva is larger than in the new species and transverse in shape; the juxta has a pair of slender lateral processes; the apical part of the aedeagus is without any spines; the vesica contains three large hooked cornuti.
Description.
Adult (Fig. 11 View Figures 7–14 ). Forewing length 7.0-7.5 mm, wingspan 16-17 mm. Head white; labial palpus white; antennae filiform, pale brown. Thorax with white scales above. Forewing ground colour greyish white, covered with sparse dark scales, a pair of large white spots in Cu-area with brown border; venation visible, brown; fringe dark brown. Hindwing greyish yellow. Abdomen brown to dark brown, mixed with white scales.
Male genitalia (Fig. 25 View Figures 21–28 ). Uncus pointed apically, without any spur. Gnathos flattened, fishtail-shaped, comb-like apically. Valva elongate, with a basal papula with long bristles; base of sacculus slightly sclerotized; cucullus narrow and rounded. Juxta flattened, weakly sclerotized, without lateral process. Saccus long. Aedeagus short, tube-shaped, thinned proximally, bearing 3-5 strongly sclerotized long spines near apical part; vesica with a pair of strongly sclerotized, peg-like cornuti.
Female. Unknown.
Bionomics.
The specimens were collected from late May to early June, at an altitude of 1,450 m a.s.l., in a subtropical forest (Fig. 30 View Figures 30–33 ).
Distribution
(Fig. 29 View Figure 29 ). China (Xizang).
Etymology.
The specific name Fignya ravalba , an adjective, is derived from the Latin “ravus” (= grey) and “albus” (= white), corresponding to the greyish-white ground colour of the forewing.
