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).
