Holotype ♂ , CHINA : Jiangxi , Qilushan , 5.V.1978 , C. Yang ( CAU ). Distribution. China ( Jiangxi ). Remarks. This species appears to be closely related to N. wuminganus in having the similar wing patterns. In N. wuminganus , the male tenth terga are symmetrical and the tenth sternum is inflated at middle in lateral view.
