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 ).

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 ).
