Distribution.

China (Yunnan), Laos and Myanmar. New to China.

Diagnosis.

The collecting locality of the male specimen is about 760 km away from the holotype locality in north-eastern Laos and about 210 km away from the paratype locality in Myanmar. The specimen fits the original description in all characters, but the medio-apical margin of the paramere looks slightly different as well as the apex of the median lobe in lateral view. The ventral view of the median lobe as depicted here is more representative of the species, as it is matching that of the other specimens of the type series. The shape of the paramere is here considered as within the variability range of this widespread species. The females correspond with the original description in all characters.
