The present paper deals with two new species of the family Salticidae. The measurement unit is in mm.1. Gedea unguiformis sp. nov (figs. 1-9)Holotype ♂, allotype ♀, Mt. Daimin (23.4°N, 108.5°E), Guangxi Province, July 13, 1985. Collected by Zhang Yong-jing. The type specimens are kept in Department of Biology, Hunan Normal University.Male Total length 4.0, length of cephalothorax 2.0, length of abdomen 1.75, length of eye field 0.85, width of eye field I 1.24, width of eye field Ⅰ 1.12. Cephalothorax dark brown, chelicerae brown, with.a tuft of long hairs in the distal part of the basal segment. In comparison with G. flavogalarif Simon, 1902 and C. tibialis Zabka, 1985-embolus relatively shorter, its tip claw-shaped, on the inner edge of chelicerae six teeth (in G. flavogularis-three, in G. tibialis-five).Female Total length 4.0, length of cephalothorax 1.90, length of abdomen 2.0, length of eye field 0.90, width of eye field Ⅰ 1.10, width of eye field Ⅲ 1.0. Similar to male. Epigyne with a vast ovalidtpression, spermathecae ballsshaped. In the posterior part of epigyne, there are two sclerotized pockets.2. Heliophanus falcatus ap. nov. (figs. 10-21)Holotype ♂, allotype ♀, paratypes 5 ♂♂ 2 ♀♀, Baiyinnaobao (43.5°N, 118.7°E), Ju Ud League, Nei Mongol Autonomous Region, June 12-15, 1972; paratypes 2 ♀♀, Ju Ud Meng, Nei Mongol Autonomous Region, May 21, 1972. The type specimens collected by Zhu Chuan-dian, and kept in Norman Bethune University of Medical Sciences.Male Total length 3.55-4.0, length of cephalothorax 2.10, length of abdomen 2.0, length of eye field 0.90, width of eye field Ⅰ 1.10, width of eye field Ⅲ 1.30. Cephalothorax dark brown with a metallic shine, widest at the level of coxae Ⅲ, legs short, pedipalp brown, femur with a fingered apophysis, tibia with two apophyses. Embolus falcate.Female Total length 3.2-4.0, length of cephalothorax 1.50, length of: abdomen 2.60, length of eye field 0.63, width of eye field Ⅰ 0.82, width of eye field Ⅲ 0.90, Similar to male in shape, but with narrow light band at anterior margin and three pairs of spots dor-sally of abdomen. Epigyne with a oval depression, and two sclerotized pockets near the middle of epigastric furrow.The new species is somewhat related to H. cupreu; (Walckenaer, 1802), but differs from the latter in the structures of male palp and female epigyne.
