Type material. Holotype: ♂, from Xiaozhuangping Village , near Tianping Mountain Forestry Station (alt. 1520m; 29°46′35.332″N, 110°05′54.474″E), Bamaoxi Town, Sangzhi County, Hunan Province, China, 17 September 2015, C.Jin, J. He leg.. Paratypes : 4♂ 2♀, same data as holotype .

Etymology. The species name is an adjective from the Latin word “ lucidus ”, which means bright, referring to the color of the male palpal bulb.

Diagnosis. Males of Clubiona lucida n. sp. are similar to those of C. qiyunensis Xu et al., 2003 ( Xu et al. 2003, figs 13–19) and those of C. pollicaris Wu et al. 2015 (Wu et al., 2015, figs 17–19), by the presence of a retrolateral femoral apophysis, but can be distinguished by the distal insertion of that structure ( Fig. 4 C). Females can be distinguished from those of both C. qiyunensis and C. pollicaris by the posteriorly positioned copulatory openings, and by the long, parallel copulatory ducts ( Figs 4 A–B).

Description. Male (holotype). Total length 3.76; carapace 1.79 long, 1.34 wide; abdomen 1.95 long, 1.18 wide ( Fig. 3 A). Carapace pale white. Both anterior and posterior eye rows recurved in dorsal view; eye sizes and interdistances: AME 0.08, ALE 0.09, PME 0.10, PLE 0.09; AME–AME 0.05, AME–ALE 0.03, PME–PME 0.16, PME–PLE 0.10. MOA 0.19 long, 0.20 anterior wide, 0.35 posterior wide; chelicerae pale yellow, promargin with 5 teeth, retromargin with 4 teeth; endites and labium pale yellow; sternum 1.01 long, 0.66 wide. Legs pale yellow, tibiae I and II with two pairs of ventral spines, metatarsi I and II with one pair of ventral spines; leg measurements: I 3.51 (1.16, 0.46, 0.89, 0.67, 0.33), II 4.05 (1.24, 0.59, 0.95, 0.82, 0.45), III 3.49 (0.92, 0.55, 0.80, 0.85, 0.37), IV 5.03 (1.36, 0.56, 1.24, 1.41, 0.46); leg formula: 4213. Abdomen oval, pale yellow, with conspicuous brown spots. Palp ( Figs 3 E–G, 4C–E). Femur with a long, thick, distally inserted retrolateral femoral apophysis; RFA approximately half the length of femur; patella with small, blunt RPA; tibia with thumb-shaped retrolateral tibial apophysis and ventral tibial apophysis triangular in dorsal view; small ridge in retrolateral tibial surface; bulb distinct expanded; embolus arched, with pointed, curved apex; tegular apophysis lanceolate in ventral view; tegulum with a distinct median process, with dark apex; sperm duct gently curved along retrolateral surface.

Female (paratype). Total length 3.92, carapace 1.86 long, 1.33 wide; abdomen 2.03 long, 1.28 wide ( Fig. 3 B). Eye sizes and interdistances: AME 0.08, ALE 0.10, PME 0.09, PLE 0.10; AME–AME 0.06, AME–ALE 0.04, PME–PME 0.19, PME–PLE 0.13, ALE–PLE 0.59. MOA 0.20 long, 0.22 anterior wide, 0.36 posterior wide; sternum 1.04 long, 0.69 wide. Leg measurements: I 3.57 (1.18, 0.47, 0.92, 0.66, 0.34), II 4.07 (1.27, 0.57, 0.98, 0.79, 0.46), III 3.52 (0.93, 0.52, 0.81, 0.87, 0.39), IV 5.18 (1.40, 0.58, 1.27, 1.45, 0.48); leg formula: 4213. Epigyne ( Figs 3 C–D, 4A–B). Atrium absent; copulatory openings small, closely spaced, placed posteriorly; spermathecae long, tubular, sinuous; bursae large, spherical; copulatory ducts almost parallel, extending anteriorly.

Variation. Total body length: male 3.20–3.49 (n=5), female 3.92–3.96 (n=2).

Distribution. Known only from Hunan, China
