All type specimens are deposited in the Medical Entomology Gallery, Institute of Microbiology and Epidemiology, Academy of Military Medical Sciences, Beijing. Pachylaelaps badongensis sp. nov.(Figs.1-5)The new species is close to P. neoxenillitus Ma, 1997 and P. xenillitus Ma, 1985, but differs from them in the following characters: 1) reticulation of sternal plate air bladder-like in shape, and with an arched curve at the sub-anterior margin;2) tarsus Ⅱ only with 1 spine, while tarsus Ⅱ of P. neoxenillitus and P. xenillitus have 3 or 5 spines; 3) the cervix of tectum shorter, basal portion wider, and the terminal and lateral margin with more of smaller teeth. In addition, the new species is similar to P. xizangensis Ma et Wang, 1997, but differs from the latter in shorter and smaller S 8 seta of dorsal plate, and its length not reaching 1/3 of S 7 seta; the apical margin teeth of tectum thicker; the each setae on tarsus of legs Ⅱ smooth. While the S 8 seta of the dorsal plate of P. xizangensis are longer, and their length exceed 1/2 that of S 7 seta; the apical margin teeth of tectum more slender and denser; some setae on tarsus of legs Ⅱ with some small branches. Holotype ♀, collected from Anourosorex squamipes in Badong County (30°8′N, 110°4′E, about 1700m), Southwest of Hubei Province on 30 Oct. 2000.Hirstionyssus anisochaetus sp. nov.(Figs.6-11)The new species is similar to H. montanus Huang, 1990,H.shensiensis Liu et Yuan, 1963, H. xinjiangensis Ye et Wang, 1981 and H. qinghaiensis Gu et Yang, 1986. It differs from the former two species in the dorsal plate only with 26 pairs of setae, I 3 absent; mutual distance between dorsal setae D 7 about equal to that of D 6, however mutual distance between dorsal setae D 7 of H.montanus distinctly shorter than that of D 6. It differs from the latter two species in the anterior and posterior margins of sternal plate being convex, and its wid
