Etymology. The specific name is the combination of the prefix “ multi -” (multiple) and the Latin “ dentatus ” (dentate), referring to the patella with a row of teeth in retrolateral view; adjective.
Diagnosis. Males and females of Clubiona multidentata n. sp. resemble those of C. submoralis Wu, Zheng & Zhang, 2015 described from Yunan, China (see Wu et al., 2015, figs 1–12), but differ by the patella with a small conical apical retrolateral apophysis, and field of retrolateral teeth arranged longitudinally (Figs 41, 47); retrolateral tibial apophysis curved downwards in ventral view (Figs 40, 46); bulb almost spherical, embolus about two times as long as its widest part in ventral view (Figs 40, 46); anterior margin of epigyne with a shallow depression (Figs 43, 49); copulatory openings located at the sides of atrial anterior border (Figs 43, 49); copulatory ducts semicircular, much longer than spermathecae (Figs 44, 50); spermathecae less than a quarter of bursae size (Figs 44, 50).
Description. Male (holotype): Total length 3.80; carapace 1.70 long, 1.30 wide; abdomen 2.10 long, 1.10 wide. Cephalothorax (Fig. 37). Carapace brownish yellow; chelicerae brown, promargin with three teeth, second largest, retromargin with two subequal teeth; endites and labium brown; sternum brownish yellow. Eyes. In dorsal view, anterior eye row slightly recurved, posterior eye row slightly procurved; AME dark, other eyes light, surrounded by black pigment; eye diameters and interdistances: AME 0.08, ALE 0.10, PLE 0.11, PME 0.11, AME–AME 0.05, AME–ALE 0.05, PME–PME 0.15, PME–PLE 0.08; MOQL 0.28, MOQA 0.23, MOQP 0.40. 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 4.0 (1.15, 1.75, 0.75, 0.35), II 4.90 (1.50, 2.0, 0.90, 0.50), III 3.63 (1.05, 1.25, 1.0, 0.33), IV 4.93 (1.25, 1.75, 1.40, 0.53); leg formula: IV, II, I, III. Abdomen (Fig. 37). Dorsum yellow, with two pairs of muscular depressions; venter light yellow; spinnerets light yellow. Palp (Figs 39–42, 45–48). Femur unmodified, without apophyses; patella swallen, bulbous, twice wider than tibia, with a small conical apical apophysis and nine retrolateral teeth; tibia short, ventral tibial apophysis absent, retrolateral apophysis curved, with blunt apex; conductor slender, membranous, longer than embolus; embolus triangular, gradually tapering toward apex.
Female (paratype): Total length 4.0. Carapace 1.90 long, 1.30 wide. Abdomen 2.10 long, 1.0 wide (Fig. 38). Eye diameters and interdistances: AME 0.08, ALE 0.09, PLE 0.10, PME 0.08, AME–AME 0.05, AME–ALE 0.05, PME–PME 0.18, PME–PLE 0.08; MOQL 0.23, MOQA 0.23, MOQP 0.35. Leg measurements: 4.20 (1.20, 1.80, 0.70, 0.50); II 4.75 (1.40, 1.90, 0.90, 0.55); III 4.10 (1.30, 1.50, 0.90, 0.40); IV 5.70 (1.60, 2.10, 1.50, 0.50); leg formula: IV, II, I, III. Epigyne (Figs 43–44, 49–50).
