This paper describs 2 new species and 1 new subspecies of Doratopsylla Jordan et Rothschild, 1911 from North-Western region of Ynnan Province, China. Two new species of them are separately named in honor of prof. Ji Shu-li and Liu Yun-peng for their outstanding contributions in the field of plague and flea studies in China. All types specimens are deposited in the Research Institute of Epidemic Diaeases of Yunnan Province.Doratopsylla jii Xie et Tian, sp. nov. (figs. 1-8)This new species is allied to D. coreana, but can be distinguished by the following characters: 1) the 2nd-5th spines more curve and the dorsal spine of the pronotal comb . not markedly longer than dorsal margin of pronotum; 2) crochet of aedeagus of male with a rounder apex, and obviously beyong the apex of median dorsal loble of aedeaugus, the posterior marging being arched insteas of a shallow sinus; 3) the posterior margin of st. Ⅶ of female being obligu’e, with its middle slightly convex, or another added a small sinus near the po-stero-ventral angle, its ventral loble somewhat longer than dorsal loble.Holotype meal, allotype female, paratypes 1 male, 2 females off Nasillus gracilis, were collected in October, 1985 from Gaoligong Mountain (the elevations 3000-3200m), Gong-shan County, NorthWestern, Yunnan Province., Body length 1.8-2.1 mm in male; 2.1-2.4mm in female.Doratopsylla liui Xie et Xie, sp. nov. (figs. 9-15)This new species is allied to D. coreana and D. jii Xie et Tian sp. nov. but easily distinguishable by the following characters: 1) the frontal tubercule arising very low, almost situated at 1/4 (in male) and 1/8 (in female) of the frontal margin; 2) the base of the 1st spine of genal comb distinctly wider than base of the 2nd and 3rd ones; 3) the basal line (lateral aspect) of pronotal comb being obinge and somewhat arched instead of subvertical; 4) the movable process of male straighter, the middle slightly wider; and the apex of crochet near truncate; 5) the posterior margin of st. Ⅶ of female with a small and protruded ven-troposterior loble.Holotype male, allotype female, paratypes 21 males, 8 females off Nasillus gracilis, other paratypes 6 males, 1 female off Sorex sylindricauda, were collected in October 1985 from Gaoligong Mountains (the elevations 2800-3000 m). Body length 1.7-2.2mm in male; 2.1-2.5 mm in female. Doratopsylla coreana jianchuanensis Xie et Yang, subsp. nov. (figs. 16-20)The new subspecies is close to D. c. araea Smit, 1976 from Nepal, but differs from the latter in the following character: 1) the 2nd-4th spines curver, and the dorsal spine of pro-notal comb slightly longer than dorsal margin of pronotum; 2) the movable process of male wider, its apex slightly higher than of immovable process (posterior loble), instead of more higher; 3) the posterior margin of St. Ⅶ of female with an ovate sinus, the postero-ventral loble shorter than dorsal loble.Holotype male, allotype female and paratype 1 female respectively off Niviventer an-dersoni, Chodstgoa salenskii, and Eothenomys miletus, were collected in July and August, 1979 and 1980 from Mt. Laojin (elevation about 3500 m), Jianchuan County, North-Western, Yunnan Province. Body length 1.8 mm in male; 2.1 mm in female.
