( Figs. 1–5)

Type material. Holotype female, CHINA: Fujian Province, Wuyi Mountain , N 26°32’, E 116°25’, Aotou, 5 July 2003, C. Zhang leg. ( MHBU) . Paratypes: 1 male, Fujian Province, Wuyi Mountain , 8 July 2003, C. Zhang leg. ; 1 male, Fujian Province, Wuyi Mountain , 17 July 2003, C. Zhang leg. ; 1 male, Fujian Province, Wuyi Mountain, Tongmu , 14 July 2003, C. Zhang leg. (all MHBU).

Diagnosis. The new species is similar to Hamataliwa puta (O. Pickard­Cambridge, 1894) ( Brady 1970: 87, figs. 21–22, 33–34, 65–67, 113–119) according to the shape of male palp, but it differs from the latter in depression of female epigynum with two longitudinal ridges, spermathecae pear­like ( Figs. 2–3); male palpal organ wide, conductor long with its tip spinous, ventral tibial apophysis thumb­like, retrolateral tibial apophysis flat ( Figs. 4–5).

Etymology. The specific name is derived from the Latin word “auritus, ­a, ­um”, and refers to the auricular basal outgrowth of cymbium of male palp; adjective.
