description: Key to the females for the world species of the genus Neparholaspis
The key provided for separation of 17 Neparholaspis world species is based on original illustrations, descriptions and examination of the paratype of N. evansi Krantz, 1960. The descriptions and figures of N. caelebs (Vitzthum, 1926) are based only on the male and do not allow inclusion this species in the key. Distribution data in China of N. unicus based on Bei et al., 2009 and N. serratichela Ishikawa, 1979 on Tseng, 1993; distribution of N. arcuatus and N. simplex in Korea reported by Kontschán et al., 2015.
