This paper deals with six species of the Genus Clubiona from China.All type specimens are deposited in Hunan Biology Research Institute.Measurement unit is mm. 1 Clubiona circulata sp.nov. (Figs.1 5) Holotype ♀,paratypes 4♀♀,2,Mengla County (21 5°N,101 5°E),Yunnan Province.March 24,1979,collected by WANG Jia Fu. Female total length 6 85 8 52,holotype total length 7 65,cephalothorax length 3 30,width 2 20;abdomen length 4 35,width 2 40.Male total length 3 45 4 65,paratype 4 65,cephalothorax length 2 10,width 1 43;abdomen length 2 55,width 1 35.Leg formula:4,2,1,3. The epigynum of this new species is allied to Clubiona parallela Hu et Li,1987,but the shape of copulatory atrium and spermatheca,as well as curve direction of copulatory duct are distinct.Also is the palpal organ distinguishable from the latter by terminal structure of genital bulb. Etymology.The specific name is derived from the curve direction of the copulatory duct. 2 Clubiona didentata sp.nov. (Figs.6 8) Holotype ,Mengla County (21 5°N,101 5°E),Yunnan Province.March 22,1979,by WANG Jia Fu. Holotype total length 3 47,cephalothorax length 1 57,width 1 07;abdomen length 1 90,width 1 02.Leg formula:4,2,1,3. Palpal organ of this new species as shown in Figs.6 8.It apparently differs from Clubiona yaginumai Hayashi,1989,by having a wider and shorter tibia apophysis,a small and a big tegular apophyses and obvious conductor. Etymology.The specific name is derived from the tegulum promargin having two dental apophyses. 3 Clubiona filoramula sp.nov. (Figs.9 11) Holotype ,Mengla County (21 5°N,101 5°E),Yunnan Province.March 24,1979,by WANG Jia Fu. Holotype total length 4 89,cephalothorax length 2 14,width 1 62;abdomen length 2 75,width 1 82.Leg formula:4,2,3,1. This new species resembles Clubiona filicata O.P. Cambridge,1874(Zhang et Hu)in palpal organ.The differences between them lie in tibia apophysis and embolus.The former's tibia apophysis with pointed end,embolus slender and twisty. Etymology.The specific name is derived from the embolus having a fibrous branch. 4 Clubiona heteroducta sp.nov. (Figs.12 13) Holotype ♀,Mengla County (21 5°N,101 5°E),Yunnan Province.March 24, 1979,by WANG Jia Fu. Holotype total length 5 52,cephalothorax length 2 38,width 2 05;abdomen length 3 14,width 1 70.Leg formula:4,2,1,3. This new species is similar to Clubiona odesanensis Paik,1990,but the shape of spermathecae and curve direction of copulatory duct are different from that of the latter. Etymology.The sepcific name is derived from the different run direction of the basal end part of two copulatory ducts. 5 Clubiona tortuosa sp.nov. (Figs.14 15) Holotype ♀,paratype 1♀,Zhenkang County (23 9°N,99°E),Yunnan Province,March 12,1978,by WANG Hai Zhen. Female total length 8 84 10 50.Holotype total length 8 84,cephalothorax length 3 84,width 2 54;abdomen length 5 00,width 3 67.Leg formula:4,2,1,3. Having a pair of large elliptical spermathecae,this new species is rather similar to Clubiona lyriformis Song et al .,1991,from which it is distiguished by arc shaped atrium pit and twisty duct. Etymology.The specific name is derived from the curvation of the coputatory duct in a zigzag. 6 Clubiona transversa sp.nov. (Figs.16 19) Holotype ♀,paratype 1,Kunming City (25 1°N,102 7°E),Yunnan Province.July 21,1981,by Yin Chang Min;paratype 1 ,Menglun,Yunnan Province.July 31,1981,by WANG Jia Fu. Holotype total length 3 87,cephalothorax length 1 92,width 1 32;abdomen length 1 95,width 1 16.Male total length 3 74 4 03,paratype total length 4 03,cepholothorax length 2 05,width 1 54;abdomen length 1 98,width 1 38.Leg formula:4,2,1,3. The epigynum of this new species resembles that of Clubiona zhangmuensis Hu et Li,1987,but the shape and twisty direction of copulatory duct are different.Besides,the palpal organ is distinguish from that of C.deletrix O.P.
