摘　　要：本文记述红螯蛛属２新种：即宁明红螯蛛Ｃｈｅｉｒａｃａｎｔｈｉｕｍｎｉｎｇｍｉｎｇｅｎｓｉｓｓｐ．ｎｏｖ．和思茅红螯蛛Ｃｈｅｉｒａｃａｎｔｈｉｕｍｓｉｍａｏｅｎｓｉｓｓｐ．ｎｏｖ．及２种雄性的补充描述：即精美红螯蛛ＣｈｅｉｒａｃａｎｔｈｉｕｍｅｘｑｕｅｓｔｉｔｕｍＺｈａｎｇｅｔＺｈｕ，１９９３和纤红螯蛛ＣｈｅｉｒａｃａｎｔｈｉｕｍｆｉｂｒｏｓｕｍＺｈａｎｇｅｔａｌ．，１９９４。模式标本保存于湖南省生物研究所。（量度单位为ｍｍ，图版中的比例尺为０１ｍｍ）。This paper deals with two new species and two male supplements of the genus Cheiracanthium from China.All type specimens are deposited in Dept.Biol.Hunan Normal University.Measurements are in millimeters.The scale lines equal to 0 10. Cheiracanthium ningmingensis sp.nov. (Figs.1 3) Holotype ♂,Ningming County(22 1°N,107 0°E),Guangxi Province,May 16,1997,leg.ZHANG Yong Jing. Male.Total length 8 28;carapace 3 36×2 78;abdomen 4 92×1 78.Body yellowish brown.Chelicera with 3 promarginal and 2 retromarginal teeth.Leg formula:1,4,2,3. This new species is very similar to Cheiracanthium japonicum Bsenberg et Strand,1906(Paik,1990:5 7,figs.1 13),but differs from the latte by:1)tibial apophysis of the new species forked at its distal end and faced to the inner side,but that of the latter didnt fork and faced to the outer;2)the retromarginal protuberance(rp) of cymbium is very distinct and situated near the anterior portion of the cymbiumm,while that of the latter not distinct and near the middle of cymbium. Famale:unknown. Cheiracanthium simaoensis sp.nov. (Figs.4 7) Holotype ♂,paratypes 1♂,2♀♀,Simao County(22 4°N,100 4°E),Yunnan Province,July 25,1981,leg.WANG Jia Fu. Male.Total length 8 76 9 15.Holotype measured.Total length 9 15;carapace 3 58×2 91;abdomen 5 57×2 16. Female.Total length 9 26 10 46.A specimen of total length 10 14.Carapace 5 08×3 39;abdomen 5 06×3 18. Male.Carapace pale reddish brown.Abdomen dorsum white yellow.Chelicera with 3 promarginal and 2 retromarginal teeth.Leg formula:1,4,2,3. This new species is similar to Cheiracanthium submordax (Zhang et al .,1993:106,figs.1 4),but can be differed from the latter by:1)tibial apophysis of the former more slender and somewhat slightly waved,that of the latter shorter and straight;2)the anterior half portion of posterior protuberance of the cymbium extends transversely,then backwards.But that of the latter gradually curves towards back.So the angle between cymbium ang its p
