( Fig. 4 : A–E)

Female. forewing 40–41mm, hind wing 39–41mm, abdomen 21–24mm.

Male. Unknown.

Head ( Fig. 4 : B-C). Eye black grayish, with small dark spots; face yellow, dark band around antennae; vertex yellow with a pair of transverse black line and a pair of triangle black marks. Maxillary palpus shiny black; labial palpus dark brown. Antenna clavate, flagellum comprising about 28 glagellomeres, black except about 15-23 flagellomeres brown.

Thorax. Pronotum ( Fig. 4-C ) longer than wide, bearing sparse black short setae, yellow with a well defined black medial stripe and a pair of lateral curved outward black arched stripes which interrupted at the middle; two big black spots and dense tiny spots on anterior 1/3 of pronotum. Mesothorax and metathorax bearing sparse black short setae, general coloration yellowish with black stripes along anterior margin, lateral margin and midline.

Legs. Foreleg: coxa mostly yellowish except basal part black, covered with sparse black long setae; femur and tibia with alternating coloration of black and yellowish; black basal part of tibia with a light brown spot at outer side; tarsus black except the basic part of the first and second segment yellowish; spurs and claws red brown; spurs straight, extending to about apex of the 2nd tarsomere or a little above. Midleg and hindleg similar to foreleg.

Forewing. The outer margin concave; venation alternating between pale and dark; anterior Banksian line distinct; posterior Banksian line indistinct; the width of costal area about same as the most width between R and Rs; Rs with 10 branches; prosectoral area with 4 crossveins; the bifurcation of Rs before cubital fork; the area of rhegma with a arched black stripe; the anastomosis of CuA and CuP+1A with a short black line; abundant black spots diffused on area near apex and outer margin. Stigma white, with many black spots surrounded; hypostigmal cell long and narrow. Hindwing. Narrower, shorter and paler than forewing; prosectoral area with 1 crossvein; Rs with 9-11 branches; the area of rhegma with a netlike mark; anastomosis of CuA and CuP+1A without spot; apex with a distinct black stripe halved apex angle; sparse black spots diffusing near stigma and outer margin; stigma white; hypostigmal longer than forewing.

Abdomen. Irregular alternating brown and black with sparse short black setae. The female genitalia as in Fig. 4-D , ectoproct oval, short and broad with sparse short dark setae; 9th-interior gonapophysis oblong with dense digging setae, 8th-interior gonapophysis fingerlike, as long as 8th-external gonapophysis.

Male. Unknown.

Material Examined. Holotype, Ƥ, Hanmi, Prov. Xizang, 95°07ʹE, 29°23ʹN. 2200m, 24.VIII.2005, Zhou Dakang leg (CAU-N 101294). Paratype, Ƥ, Hanmi, Prov. Xizang, 95°07ʹE, 29°23ʹN. 2200m, 26.VIII.2005, Zhou Dakang leg (CAU-N 101295).

Distribution. China (Xizang).

Etymology. nigri - L. black; vena L. vein; referring to this species with many black veins.

Remarks. The new species is similar to G. angulineura ( Yang, 1987) , but may be distinguished from it by the latter having wings long and narrow, with the outer margin smooth, and without distinct black stripe that halves the apex angle of the hind wing.
