Length ofidiosoma about 750 Ixm. Dorsal shield covered entire do Dum, and extending to venter, dorsal setae short and simple. Presternal shields 1 pair, chela-shaped. Posterior 0aaron of sternal shield concave, with 3 pairs of setae and 2 pairs of pores on the shield. Metasternal setae situated at cuticle between sternal and endopodal shields. Genito-ventro-anal shield strongly expanded, with 6 pairs of preanal setae and 3 perianal setae. Ad l ying before level of middle of anus, both Ad and PA slightly longer than anus. Exopodal shields projected behind eoxae IV. Metapodal shields 1 pair, club-shaped, near to posterior end of exopodal shield. Peritreme reaching to gnathosomal base anteriorly. Ventral cuticle setae min^ute. Legs setae short and simple. The new species is similar to Pristolaelaps tasmani, cus Womersley, 1956, but in female of the new species posterior margin of sternal shield concave, genito-ventro-anal shield strongly expanded; in the latter species posterior margin of sternal shield convex, genito-ventro-anal shield slightly expanded. Holotype ♀, ex soil, from Tainan（23° 19＇ N, 120° 18＇ E）, Taiwan, China, 17 July 2010. Type specimen is deposited in the Medical Entomology Gallery, Institute of Microbiology and Epidemiology, Academy of Military Medical Sciences, Beijing. The new species is named after genito-ventro-anal shield of female strongly expanded. 2 Pristolaelaps paratasmanicus （Ryke, 1962）, com. nov. （Fig. 2） Ololaelaps paratasmanicus Ryke, 1962 New record from China. Female. Length of idiosoma 645 p^m, width 441 t^m. Dorsal shield covering entire dorsum, dorsal setae fine. Presternal shields 1 pair, chela-shaped. Sternal shield with convex ap{rr^or margin, posterior margin strongly convex, ending at level of middle of coxae HI, with 3 pairs of setae/andS2 pairs of pores. Metasternal setae situated on interior mar
