Diagnosis. Forewing length is 17–17.5 mm in males (17 mm in the holotype) and 19 mm in females. Externally, the new species ( Figs 6–8 ) can be easily distinguished from other relatives with whitish hindwing including female of G. mubupa sp. n. by its brownish grey frons and orange collar (both are yellow in other species). The male genital capsule of G. longivesica sp. n. ( Figs 22, 23 ) is similar to that of G. nanlingica ( Figs 17–19 ) and G. sinotibetica ( Figs 24–26 ) due to the relatively narrow valva. However, differs clearly from other relatives by the conspicuously elongated aedeagus vesica. In addition, compared to that of G. sinotibetica , the aedeagus of G. longivesica sp. n. is significantly broader and more elongated. The subbasal diverticulum of the new species is larger than that of G. nanlingica and G. sinotibetica , the subbasal chamber of vesica is less prominent than that of G. sinotibetica and bears much smaller spines than that of G. nanlingica . The female genitalia of G. longivesica sp. n. ( Fig. 34 ) differ from those of other members of the species-group by the narrow, elliptical corpus bursae (that is sack-like or globular in other species) with a narrower area of spinulose scobination.

Distribution. North Thailand (Chiang Mai Province) and Southwest China (western Yunnan Province).

Etymology. The specific epithet refers to the male aedeagus vesica shape, which is the longest in the speciesgroup.
