In this paper five new species of laelapid mite from China are described and figured, of which four belong to the genus Cosmolaelaps and one to Haemolaelaps. The were all collected off ants Myrmos spp. or from their nests, in 1988—1989, from Haiyuan County (36.5°N, 105.6°E),, Ningxia Autonomous Region. Type materials are deposited in the Ningxia Institute of Endemic Disease Control.Haemolaelaps latiporus sp. nov. (figs. 1—5)The new species may be differenciated from all other species of the genus by the follwing combined characters: Idiosoma small, 450μm in length; dorsal plate bearing 39 pairs of small setae and 3 accessory setae, with 15 pairs of lyriform pores, among them 8 pairs long and distinct, 1 pair on the inner side of M_(7-8) large and pear-like; metapodal plates 5 pairs, the largest one very long, 42μm in length.Holotype ♀ was collected from the nest of ant, on June 5, 1988.Cosmolaelaps chini sp. nov. (figs. 6—12)This new species near to Cosmolaelaps vacuus(Michael, 1891), but the dorsal plate not covering the whole dorsum; F_1 leaf-like, M_(10-11) scimitar-like, length of S_8 twice as M_(11); femurs of legs Ⅱ and Ⅳ bearing 1 and 2 cuneiform setae respectively.Holotype ♀ and paratype 1♀ collected on June 9, 1988, paratype 1♀ collected on May 17, 1989, all collected off ants.Cosmolaelaps line sp. nov. (figs. 13—18)The new species closely related to the former new species, C. chini, but the dorsal setae wider; the special setae on femurs of legs Ⅱ and Ⅳ in different shape; and the outer side of peritreme with denticles.Holotype ♀ was collected from ant, on June 5, 1988.Cosmolaelaps wangae sp. nov. (figs, 19—23)This new species near to Cosmolaelaps ornatus Berlese, 1903, but dorsal plate not covering the whole dorsum; F_1 leaf-like, 2 unpaired accessory setae situated between the D_(5-8); posterior margin of sternal plate convex; a pair of setae on the genitoventral plate.Holotype ♀ was collected from nest of ants, on June 6, 1988.Cosmolaelaps ningxiaensis sp. nov. (figs, 24—29)The new species near to Cosmolaelaps vacuus (Michael, 1891), but dorsal setae bearing 1 more accessory seta; genito-ventral plate beaker-like; and the central prong of tecum shorter than the lateral prongs.Holotype ♀ and paratypes 4♀♀ collected on May 27, 1989, paratype 1♀ collected on June 9, 1988, all collected off ants.
