The present paper deals with four species of the genus Clubiona from China. Among them, three species are new to science: and the male of Clubiona baimaensis Song et Zhu is described for the first time. All type specimens are deposited in the College of Life Sciences, Hebei University. All measurements given are in millimeters. Clubiona lirata sp. nov. (fig. 1) Holotype , paratypes 1 ,1 , Mt.

ALE-AME = 0. 10, AME-AME = 0. 13, PLE-PME = 0. 23,PME-PME = 0. 33. MOA 0. 38 long, front width 0. 38, back width 0. 60. Clypeus 0. 05. Promargin of furrow with four or five teeth, retromar-gin with two teeth. Femur I, II, III with five dorsal spines; Femur IV with six dorsal spines. Tibia I, II with two pair ventral spines. Metstarsus I, II with a pair ventral spines. Leg measurements: I 5. 25 (1.58+2.09+0.92 + 0.66); Ⅱ5.40(1.63+2.19 + 0.97 + 0.61); Ⅲ 5.10(1.58+1.79 + 1.22 + 0. 51); Ⅳ 6.89 (1.94 + 2.50+1.84+0.61). Leg formula: 4213. Male Total length 4. 69: cephalothorax 2. 24 long, 1. 63 wide, abdomen 2. 45 long, 1. 43 wide. ALE>AME = PME = PLE(0. 12:0. 10:0. 10:0. 10).

Etymology The specific name is due to the structure of base of embolus. Diagnosis The female of this new species resembles Clubiona caerulescens L. Koch, 1867, but can be distinguished from the latter in the copulatory tube shorter; spermathecal tube convoluted and more complicated. The male resembles Clubiona papillata Schenkel, 1936, but can be distinguished from the latter in the ventral process of the tibial apophysis smaller; embolus extending backward and reaching the middle part of the tegulum. Clubiona forcipa sp. nov. (fig. 2) Holotype , paratypes 2 , 1 , Nantai (39.8° N),118. 0° E), Mt. Xiaowutai, Hebei Province, July 12, 2002, by ZHU Ming-Sheng; paratype 1 , Nantai (39.9° N,115° E), Mt. Xiaowutai, Hebei Province, July 13, 1999, by ZHANG Feng; paratypes 4 ,2 , Nantai (39. 8°N, 118. 0°E), Mt. Xiaowutai, Hebei Province, July 12, 2002, by ZHANG Feng et al..

ALE-AME = 0. 13, AME-AME = 0. 17, PLE-PME = 0. 30, PME-PME = 0. 36. MOA 0. 36 long, front width 0. 43, back width 0. 67. Clypeus 0. 07. Promargin of furrow with four teeth, the third largest, retromargin with two teeth. Femur I, II, with four dorsal spines; Femur III, IV with five dorsal spines. Tibia I, II with two pairs ventral spines. Metstarsus I, II with a pair ventral spines. Leg measurements: I 6.93(2.04+2.96 + 1.22+0.71); Ⅱ 7.24(2.04 + 3.06 + 1.22 + 0.92); Ⅲ 6.53(1.36 + 2.45 + 1.53+0.61); Ⅳ 9.09(2.65 + 3.37 + 2.65 + 0.42). Leg formula: 4213. Male Total length 5. 61-6. 73. A male of total length 5. 61: cephalothorax 2. 55 long, 1. 94 wide, abdomen 2. 75 long, 1. 73 wide; ALE>AME = PLE = PME(0. 14: 0. 12: 0.12: 0. 12), ALE-AME = 0. 08, AME-AME = 0. 10, PLE-PME = 0. 20, PME-PME = 0. 20.
