Three new species of the subfamily Parasitinae are described in the paper. All the type specimens were collected from Qianguoerluosi Mongolian Autonomous County (45 °?N, 125°?E), Jilin Province, and deposited in the First Institute of Endemic Diseases Research, Jilin Province.1. Parasitus imitofragilis sp. nov.(figs. 1-14)This new species is most likely to be confused with Parasitus fagilis Ma, 1986, but differs in new female mite provided with a semicircular structure in the genital area; in the male the setae Mst and Ⅵ 00000 1 being normal, not bifurcating at apex of corniculus, the spurr on femur n and genu n narrower than those of P. fragilis, and the spur on tibia n sharp.Holotype female and allotype male, off Citellus dauricus Brandt, Ⅴ . 1975. Paratypes 2 females, 1 male and 15 deutonymphs, off bodies and nests of Citellus dauricus, Cricetulus triton winton, Allactaga sibirica Forster and Mus musculus Linnaeus, Ⅳ-Ⅶ 1975. coll. Ma Liming.2. Vulgarogamasus qiangorlosana sp. nov. (figs. 15-28)This new species is near to Vulgarogamasus squarrosus Ma, 1987, but differs in distinct presternal shields, setae St1-St3 and Mst being smooth; with lateral margin deeply concave before level of anterior margin of anus on female anal shield, not completely coalesced with ventral shield, spines on apex of tarsus n have become short and stout pilous setae in form; in male , apex of the fixed chela being relatively acuminate with two indentions on dorsal side and two teeth on inner edge, movable chela lacking notch at apical side, corniculus without notch on inner edge.Holotype female, allotype male and paratypes 1 female, 1 male and 4 deutonymphs, off Cricetulus triton Winton and Cricetulus barabensis Pallas, Ⅴ . 1975. coll. Ma Liming.3. Vulgarogamasus dongbei sp. nov. (figs. 29-39)The new species is closely allied to Vulgarogamasus trifidus Ma, 1987 and Vulgarogamasus qinghaiensis Gu et Yang, 1987, and it is rather similar to the former because there is a tooth on the lateral margin of genital shield. Distinction for three species are shown as in the following table. Holotype female and allotype male, off M yospalax aspalax Pallas, Ⅴ . 1974. coll. Ma Liming.
