The present paper deals with 1 new generic record, 1 new species and 2 new record species. Cariphantes glumaceus sp. nov. (figs. 1—5) Holotype ♀, allotype ♂, paratypes 3♀♀ 5♂♂, Altay City (47.8°N, 88.1°E, alt. 1080 M), Xinjaing Uygur Autononous Region. July 12, 1991. All specimens are deposited in the Department of Biology, Norman Bethune University of Medical Sciences. Female Total length 1.67mm. Carapace 0.64 mm long, 0.51mm wide;abdomen 0.97mm long, 0.68mm wide. Anterier eye row (AER) recurved slightly and pesterior eye row (PER) procurved. Chelicerae with 6 promarginal teeth and 3 retromarginal teeth. Leg formula 4123. Tm 1 ca. 0. 39. Abdomen grey—yellow with 4 light impressed dots dorsally. Male Total length 1.50mm. Carapace 0.69mm long, 0.55mm wide;abdomen 0.81mm long, 0.49mm wide. Carapace yellow—brown or pale—yellow, with 4～6 short bristles directed forward at the center of the clypeus. Chelicerae with a pointed boss anteriotly. Tm Ⅰ ca. 0.38. Palpal tibia with 2 apophyses, one of them is membranous and transparent. This new species resembles Cariphantes saretorum (Hull, 1916), but differs from the latter in the shape of tibial apophyses of male palp, embolus as well as the dorsal and ventral structures of the epigynum. Cariphantes pseudosaxetorum Wunderlich, 1979 (figs. 6～7)and Cariphantes samensis Oi, 1960 (figs. 8～10)are described for the first time in China.
