See the diagnosis of K. ningboensis (Yin, Bao & Zhang, 1996). Description. Male (Fig. 11 A). Total length 7.40. Prosoma 4.13 long, 3.17 wide; opisthosoma 3.68 long, 2.38 wide. Carapace greyish brown. Eye sizes and interdistances: AME 0.14, ALE 0.14, PME 0.31, PLE 0.30; AME – AME 0.10, AME – ALE 0.07, PME – PME 0.28, PME – PLE 0.35. Clypeus height 0.22.

Retrolateral tegular apophysis with two arms (triangular-like anterior arm and hook-like posterior arm) and with a groove on the dorsal surface (maybe functioning as conductor). Female (Fig. 11 B). Total length 9.40. Prosoma 4.47 long, 3.31 wide; opisthosoma 5.43 long, 3.83 wide. Eye sizes and interdistances: AME 0.17, ALE 0.15, PME 0.37, PLE 0.33; AME – AME 0.13, AME – ALE 0.09, PME – PME 0.31, PME – PLE 0.41. Clypeus height 0.28. Leg measurements: I 10.46 (2.95, 3.94, 2.43, 1.14); II 9.77 (2.89, 3.45, 2.32, 1.11); III 10.26 (2.97, 3.49, 2.64, 1.16) IV 14.07 (3.77, 4.51, 4.19, 1.60). Epigyne (Figs 11 C, D). Septum under epigynal plate, T-shaped. Copulatory openings slit-like, located on the shoulders of septum. Stalk of spermatheca S-shaped, head of spermatheca spherical. Fertilization ducts crescent-shaped. Distribution. China (Chongqing, Guizhou, Hubei, Hunan, Jiangxi, Jiangsu). Remarks. Yin et al. (1993) regarded the specimens collected from Hunan (Sangzhi, Chengbu, Ningxiang, Changsha) as Arctosa kwangreungensis. Chen and Song (1999) regarded the specimens collected from Badong, Hubei as A. fujiii. Yu and Song (1988) described Pardosa zhui based on the holotype from Ji’an, Jiangxi. After observing the specimens collected from Hunan, Badong, and Ji’an, and comparing them with the type specimens of A. fujiii and the attached figures in the description of A. kwangreungensis Paik & Tanaka, 1986, the specimens from these places are neither A. fujiii nor A. kwangreungensis, but Pardosa zhui. Therefore, here we conclude that the records of A. fujiii and A. kwangreungensis in China are all misidentified and all refer to Kuncosa zhui.
