Etymology. The specific name is the combination of the Greek “ dactylus ” (finger) and the suffix “ -inus ” (similar), referring to the digitiform conductor; adjective.
Diagnosis. Males and females of Clubiona dactylina n. sp. resemble those of C. cylindrata Liu, Yan, Griswold & Ubick, 2007 also described from Yunnan, China (see Liu et al., 2007, figs 11–15), but differ by the ventral tibial apophysis extending diagonally upwards in retrolateral view (Figs 17, 22); embolus originating from the top of the bulb, with only the upper half filiform in prolateral view (Figs 15, 20); conductor digitiform, separated from embolus in ventral view (Figs 16, 21); atrium semicircular, slightly wider than long, with wide band-shaped anterior margin, (Figs 18, 23).
Description. Male (holotype): Total length 5.25; carapace 2.50 long, 1.90 wide; abdomen 2.75 long, 1.40 wide. Cephalothorax (Fig. 13). Carapace brownish yellow, chelicerae reddish brown, promargin with three teeth, the median largest, retromargin with two subequal teeth; endites and labium reddish brown; sternum brownish yellow, with dense hairs. Eyes. In dorsal view, anterior eye row slightly recurved, posterior eye row slightly procurved; AME dark, remaining eyes light, surrounded by black pigment; eye diameters and interdistances: AME 0.13, ALE 0.15, PLE 0.15, PME 0.13, AME–AME 0.08, AME–ALE 0.05, PME–PME 0.25, PME–PLE 0.15; MOQL 0.38, MOQA 0.35, MOQP 0.53. Legs yellow; tibiae I and II with two pairs of ventral spines, metatarsi I and II with one pair of ventral spines; leg measurements: I 5.95 (1.75, 2.0, 1.60, 0.60), II 6.95 (1.90, 2.85, 1.40, 0.80), III 5.85 (1.65, 2.35, 1.20, 0.65), IV 8.70 (2.40, 3.30, 2.0, 1.0); leg formula: IV, II, I, III. Abdomen (Fig. 13). Dorsum light yellow, with two pairs of muscular depressions; venter and spinnerets light yellow. Palp (Figs 15–17, 20–22). Femur and patella unmodified, without apophyses; ventral tibial apophysis short and blunt, retrolateral tibial apophysis dark, sclerotized, with cuspidal apex; cymbium almost as long as bulb; bulb elongate-oval, strongly bulged, posterior margin extending over patella, sperm duct indistinct in ventral view; conductor digitiform, membranous; embolus long, with wide base, upper half part filiform, extending above the top of cymbium.
Female (paratype): Total length 6.60; carapace 2.90 long, 2.0 wide; abdomen 3.70 long, 2.40 wide. Cephalothorax (Fig. 14). Chelicerae promargin with four teeth, the third largest, retromargin with two subequal teeth (Fig. 14).
