In this paper two new species of Salticidae from China are described. Type specimens are deposited in Hunan Biology Research Institute, Changsha, and Bethune Medical University, Jilin.Plexippoides validus sp. nov. (figs. 1-4)Measurements (mm) and Characters:Total length 8.46. Cephalothorax length 3.91, length of eye field 1.55, width of eye field Ⅱ 2.45, width of eye field Ⅲ 2.27. Abdomen length 4.55.Holotype cf, Mt. Fanjingshan (27°52'N, 108°42'E), Guizhou Province, June 24, 1985, collected, by Zhu Chuan-dian.The palpal organ of the new species resembles P. starmuehlneri (Roewer, 1955), but differs from the latter in stronger tibia apophysis and the shape of genital bulb.Portia heteriodea sp. nov. (figs. 5-13)Total length 8.20 (♂), 8.80 (♀). Cephalothorax length 3.45 (♂), 3.80 (♀); length of eye field 1.50 (♂), 1.45 (♀); width of eye field Ⅰ 2,28 (♂), 2.30 (♀); Width of eye field Ⅲ 2.20 (♂), 2.25 (♀). Abdomen length 4.75 (♂), 5.00 (♀).Holotype ♂, allotype ♀, National Forest Park of Zhangjiajie, Dayong County (29°8'N, 110°25'E), Hunan Province, August, 1981, collected by Wang Jia-fu; paratype 2♂♂ 2♀♀-1♂, Dayong County, Hunan Province, June 14, 1985, by Zhu Chuan-dian; 1♂, Meitan County (27°45'N, 107°28'E), Guizhou Province, Li Fu-jiang; 1♀, Mt. Emeishan (29°32'N, 103°14'E), Sichuan Province, by Zhu Chuan-dian, Sep. 23, 1975; 1♀, Mt. Qingchengshan, Sichuan Province, August 19, 1978, by Zhu Chuan-dian.The new species is similar to Portia labiata (Thorell, 1887) in the structure of palpal organ, but the outer-lateral apophysis on tibia is shorter and stouter. The palpal organ is also allied to P. assamensis, but easily distinguished from the latter in tibia apophysis smooth at the end, without indentation and in membraneous conductor accompanying with embolus.Epigynum and its variability are shown in figs. 10-13, Spermathecae piriform. These are different from P. labiata and P. assamensis.
