♂ (IZCAS-Ar 34759, YHCLU0056),: Yunnan Province: Xishuangbanna: Mengla County: Menglun Town: XTBG, Anogeissus acuminata Clubiona plantation, 21°54.033'N, 101°16.900'E, ca. 606 m, 2.VIII.2018, Z.G. Chen et al. leg.

Etymology.

The specific name is taken from its similarity to Clubiona tongi; modified noun (name) in genitive case..

Diagnosis.

Clubiona subtongi sp. nov. resembles C. tongi (Yu and Li 2019b: 212, figs 9A-E, 10E, F; Figs 57B, 67B) by having similar pale colouration and habitus (Fig. 29; Yu and Li 2019b: fig. 10E, F) and general shape of the palp (Figs 28A-E, 57B, 67B; Yu and Li 2019b: 212, fig. 9A-E) but can be distinguished by the: (1) embolar apex terminating at approximately the 4 o’clock position (Figs 28D, 57D) (vs. relatively longer tip terminating at approximately the 5 o’clock position; Figs 57B, 67B); (2) tegular hump that is ca. 1/5 tegulum length (Figs 28D, 57D) (vs. tegular hump ca. 1/3 tegulum length; Fig. 57B); (3) tegular base is unmodified (Figs 28B, 57D, 67D) (vs. with a papilliform flange; Fig. 67B).
