Diagnosis. The forewing length is 13.0–14.0 mm in males and 14.0–16.0 mm in females. The species has a somewhat broader yellow costal stripe of the forewing than the congeners of the G. typica species-group and is very similar to G. conica and G. jieenchenae from which, however, differs in the grey forewing cilia. The genital differences between G. vietnamica and the species of the G. typica species-group are discussed above in the diagnosis of the current species-group. The comparison with species of the G. conica species-group is provided below in the diagnosis of the latter.

Distribution. Vietnam (Lào Cai and Kon Tum Provinces) ( Dubatolov 2012), northern Laos (Houaphanh Province) (Bucsek 2020), northern Thailand (Chiang Mai and Nan Provinces) ( Černý & Pinratana 2009, partim.) and north-eastern India (north of West Bengal).
