Figs. 11 , 23

External characters. Wing span 14mm. Head white; frons and antennae yellow-brown; labial palpi yellow brown, upturned. Forewing silvery white, suffused with fuscous scales; medial line fuscous, from middle of costa to discocellulares, then bent to inner margin; a dark fuscous spot at the lower angle of cell; submarginal with two lines, the inner line fuscous, from costa to vein M1 then bent inwards to anal angle, the outer line yellow, adjacent to and paralleled with the inner line; several orange-yellow longitudinal fasciae along the veins outside the discocellulares; marginal area suffused with orange-yellow longitudinal fasciae along the veins and a black spot between M3 and Cu1; a fine black marginal line from apex to middle of outer margin; cilia silvery white. Hindwing silvery white; cilia silvery white.

Male genitalia. Uncus strong, the apex pointed, ventral with a tuft of thick setae; gnathos tapering pointed, slightly curved to dorsal; tegumen triangular, elongate; valva broad, protruding at apex, costal arm strong, much longer than valva, apart from the valva, the middle of costal arm with a spine-like process, the apex of costal arm strong pointed, curved upwards; juxta plate-like, apically with two papillate processes; aedeagus elongate, with a row of cornuti.

Holotype. IZCAS: 3, Xizang, Mêdog, Maniweng (29.27ºN, 96.17ºE), 895m, 2006. VIII.14, leg. Chen Fuqiang (genital slide number C1699).

Distribution. China (Xizang).

Remarks. This species is similar to G. bilineata sp. nov. in external characters, but this species has the forewing suffused with more fuscous scales and several orange-yellow longitudinal fasciae along the veins outside the discocellulares which may be specific of this species. In male gentalia, this species is similar to G. distigma sp. nov., but this species with a row of spine-like cornuti in aedeagus, while G. d i s t i g m a without cornutus in aedeagus.

Etymology. The name is derived from the Latin “ fuscus ”, corresponding to the fuscous forewing.
