Jiang & H.M. Chen leg. Remarks. The characters of the habitus and the gonopods of this species are shown in Figs 26–27 . Sellanucheza is a small genus containing six species distributed in China (three species in Sichuan , Chongqing and Shaanxi ) and northern Vietnam . The generic name has been changed from Szechuanella Hoffman, 1961 to the anagram Sellanucheza because of preoccupation ( Enghoff et al . 2004 ), and the original name refers to Sichuan Province , China . The type locality of S. jaegeri is in Houzhenzi, Shaanxi , about 400 km from Yintiaoling. Further investigation of the actual distribution range of this species is needed, especially on some areas of south slope of Qinling Mountains.
