Etymology. The specific name is a patronym in honor of the collector of the holotype, Guo Tang (the College of Life Sciences, at the Hunan Normal University) who passed away in 2014; noun.

Diagnosis. Males and females of Clubiona tangi n. sp. resemble those of C. biforamina n. sp., but differ by the triangular ventral tibial apophysis, extending transversely in ventral view ( Figs 54 , 59 ), with blunt apex in retrolateral view ( Figs 55 , 60 ); spermatic duct inverted S-shaped in ventral view ( Figs 54 , 59 ); conductor with folded apex, base about as wide as apex in ventral view ( Figs 54 , 59 ); atrium elliptic, enclosed, posterior border with a small helicoid median protuberance ( Figs 56 , 61 ); copulatory openings semicircular, located at lateral atrial borders ( Figs 56 , 61 ); copulatory duct clearly visible in dorsal view ( Figs 57 , 62 ); head of spermathecae almost longitudinal, about two times wider than spermathecae base ( Figs 57 , 62 ).
