The present paper deals with 2 new species and 1 new record of the genus Fissicepheus from China. 1. Fissicepheus chinensis sp. nov.(figs. 1～6) Body length 612(650)696μm, width 312(324)340μm. This new species resembles F. mitis Aoki, 1970 from Japan, but it can be distinguished from the latter by:(1) lamellar setae long and curved inward; (2) sensillus long, with a distinct round head; (3) surface of genital and anal plate smooth; (4) different body size. Holotype and 17 paratypes(86—504), 20. Ⅳ. 1986, Langshan(32°N, 120.8°E), Nantong City,Jiangxu Prov., by Wang Xingzhang. 2. Fissicepheus ornithorrhynchus sp. nov.(figs. 7～11) Body length 792μm, width 410μm. This new species is similar to F. caviopsis Mahunka, 1971 in the 14 pairs of notogastral setae, body shape and size, sensillus and arrangement of notogastral setae, but differs from the latter in: (1) anterior end of lamella bird beak shaped; (2) new species with distinct median condyles on prodorsum and notogaster. ' Holotype(88—1170), 17. Ⅳ. 1988, Qingchengshan(30.9°N, 103,5°E), Sichuan Prov., by Gao Jiuchun. 3. Fissicepheus mitis Aoki, 1970(figs. 12～14) New record from China. Found in litter from Qingchengshan, Sichuan Prov., 17. Ⅵ. 1988(88—1171).
