Oberthiir's figure is not very accurate. On the under surface of the fore wing 

 the heart-shaped postdiscal spot in space 5 should be whiter and more sharply 

 defined, whilst on the under surface of the hind wing the discal band should be 

 almost pure white. 



In his original description Oberthiir says he is not certain whether this is a good 

 species or a stable variety of N. arachne. It occurs in both sexes and shows exactly 

 parallel variation with N. arachne in Szechwan and N.W. Yunnan respectively. 

 This, however, is not proof of conspecificity, as parallel variation is the general 

 rule in these areas. I retain it as a good species provisionally. If in future it is 

 proved to be a species a distinct subspecies will need to be described from the 

 Upper Mekong Valley.
