Abstract: We collected 21 species of Rodentia and Insectivora in Guizhou Province from 1978-1988. Using hierachical analysis which is an important method of numerical taxonomy, the gamasid mite communities on 21 hosts (R0dentia and Insectivora) were divided into seven types. The gamasid mite communities on Rattus norvegicus, Rottus flavipectus and Mus musculus were the same types, and their dominant species were Laelaps echidninus and Ornithonyssus bocoti; Eothenomys miletus and Eothenomys melanogoster were the same types, and their dominants were Loelaps ehini; Rattus nitidus and Rottus losea were the same types, and their dominants were Loelaps echidninus and Laelaps nuttalli: Niviventer fulvescens and Nioiventer confucianus were the same types, their dominants were Laelaps echidninus and Loelops turkestonicus: Apodemus agrorius and Crocidura attenuata were the same types, their dominants were Laelaps echidninus and Tricholaelaps myonyssognathus; Mus pahari and Rattus bowersi were independent types, the former's dominants were Laelaps guizhouensis and Loelaps paucisetosa, and the later was Laelaps turkestanicus. It is difficult for the gamasid mite communities on the rest hosts to be divided into certain types because the samples of hosts were too less
