Material examined.

Holotype: China • ♂, Xizang Autonomous Region, Xigaze City, Yadong County, Pangda Village ( 27°21'N, 88°59'E), alt. 2382 m, 23 July 2024, W Li and X He et al. leg. ( JXAUM) . Paratypes: • 5 ♀♀, same data as holotype ( JXAUM) ; • 1 ♂, 1 ♀, same data as holotype ( NZMCAS) ; • 5 ♂♂, 6 ♀♀, Xizang Autonomous Region, Shannan City, Cuona County, Lebugou ( 27°49'N, 91°44'E), alt. 2629 m, 16 July 2024, W Li and X He et al. leg. ( JXAUM) .

Diagnosis.

In male genitalia, the gnathos distally with a triangular projection on dorsal margin and a protuberance on ventral margin, and the cornuti consisting in a cone-like process and a row of tiny spines. In female genitalis, the ductus posterior one-third slightly sclerotized, and the corpus bears double and rounded signa. This species is similar to G. taphrophracta ( Meyrick, 1934) in the triangular projection on the dorsal margin of the uncus in male genitalia (Fig. 1 C versus Wang et al. 1988: fig. 87). It can be distinguished by the concave costa, and cornuti consisting in a cone-like process and a row of tiny spines of various sizes (Fig. 1 C ). Whereas in G. taphrophracta , the costa is almost straight and the vesica of the phallus bears two thin and long cornuti ( Wang et al. 1988: 375, fig. 87).

Description.

Adult habitus (Fig. 1 A, B ). Forewing length 6.0–7.0 mm. Frons and vertex white. Labial palpus first and second segments uplifted, third segment projecting forward; outer side surface pale yellow mixed with brown except for first segment white at base. Maxillary palpus white mixed with brown. Antenna alternately pale brown and yellowish brown on dorsal surface. Patagium pale yellow. Tegula blackish brown. Thorax pale yellow. Forewing densely covered with black scales on inner side of antemedian line, pale yellow along dorsum; antemedian line white, inner margin wavy; reniform stigma unrecognized; postmedian line yellowish brown, outcurved at costal one-third; apex black, with white spot; termen black mixed with yellowish brown, with three black marginal spots; fringe blackish brown mixed with yellowish white. Hindwing yellowish white; postmedian line pale brown; apex scattered with pale brown scales; fringe yellowish white mixed with pale brown. Legs yellowish white; tarsi alternately black and white. Abdomen with first and second segments grey, genital segment yellowish white, other segments alternately brown with yellowish white.

Male genitalia (Fig. 1 C ). Uncus base broad, narrowed towards blunt apex. Gnathos slightly longer than uncus, distal apex with triangular projection on dorsal margin, and protuberate on ventral margin. Tegumen approximately twice as long as gnathos. Valva with basal half broader than distal half, gently concave near middle of ventral margin, apex round, costa gently concave. Saccus well-developed. Juxta elliptic. Phallus nearly as long as valva, cornuti consisting in cone-like process and a row of tiny spines of various sizes.

Female genitalia (Fig. 1 D ). Papillae anales about half as long as apophyses posteriores. Apophyses anteriores thin and long, nearly as long as apophyses posteriores. Ductus bursae thin and long, posterior one-third slightly sclerotized. Ductus seminalis arising from approximately anterior one-third of ductus bursae. Corpus bursae rounded; signa double and rounded.

Etymology.

This species is named in honour of Academician Fuwen Wei, a renowned conservation biologist who has made profound contributions to biodiversity, zoological evolution, and conservation biology.
