The genus Synagclides Strand, 1906 contains at present 8 species, distributed in Primore (USSR), Japan, Korea, China, Bhutan and Nepal. Only one was recorded in China. This paper describes two new species and three newly recorded species of the genus Synageoides from China.All type specimens are deposited in the Department of Biology, Hunan Normal University, Changsha.Synagelides gambosa sp. nov. (figs. 1-7)Measurements (mm) and Characters.Total length 3.55 (♂), 5,00 (2). Cephalothorax length 1.64(♂), 2.00 (♀); length of eye field 0.95(♂), 1.15(2); width of eye field I 1.18(♂), 1.45(2); width of eye field III 1.23(♂), 1.45(♀)2 Abdomen length 1.91(♂), 3.00(♀).Holotype ♂, allotype 2, paratype 1♂. National Forest Park of Zhangjiajie, Dayong County (29°8'N, 110°25'E), Hunan Province, August 1981, collected by Wang Jia-fu.The palpal organ of the new species is allied to Synagelides agoriformis Strand, 1906, but differs in: 1. length of embolus, shorter in the new species; 2. the shape of sclerotized plate in embolus vicinity.Synagelides lushanensis sp. nov. (figs. 8-15)Total length 4.33(♂), 5.10(♀); Cephalothorax length 1.93(♂), 1.80(♀); eye field length 1.17(♂), 1.00(2); width of eye field I 1.33(♂), 1.25(♀); width of eye field III 1.43(♂), 1.35 (♀). Abdomen length 2.40 (♂), 3.30(♀).Holotype ♂, allotype ♀, paratypes 10♂♂, 18♀♀. Lushan Mountain (115°55'E, 29°30'N), Jiangxi Province, June 15, 1987, collected by Wang Jia-fu, Peng Xian-jing, Xiao Xiao-qin and Xie Li-ping.The palpal organ of the new species resembles Synagelides polpalis Zabka, 1985, but differs in: 1.the shape of bulbus; 2. embolus and the shape of accompanying sclerotized plate; 3. epigynum of female.Synagelides agoriformis Strand, 1906This species is newly recorded in China. Distribution Japan, North Korea, USSR, China. Synagelides zhilcovae Proszynski, 1979This species is newly reported in China.Distribution: USSR, China.Synagelides annae Bohdanowicz, 1979.(figs. 16-19)This species is recorded for the first time in China. In comparison with the Japanese species, the structure of palpal organ is same, small difference in the shape of accompanying structure with embolus.Distribution: Japan, China.
