Using the Cobb filtered method, the writer has gotten 75 tardigrad specimens from these mosses,including 3 new species, 8 new records and 2 known species. An entire list of species including some notes are given in this paper.Heterotardigrada Marcus, 1927 Echiniscoidea Marcus, 1927 Echiniscidae Thulin, 1928 Echiniscus Schultze, 1840Echiniscus angolensis da Cunha et do Nascimento Ribeiro, 1964 (Fig.1) Two specimens were found in the area of 3*!200*!m altitude of Lijiang County.Body length 121-150*!μm. In the form of pattern of small pores on the dorsal plates, without eyes. Three median plates of dorsum are not transversely divided. Posterior lateral margins of every two lateral plates with a pair of filamentous appendages. Posterior lateral angles of the 1st and 2nd paired lateral plates separately with a pair of convex spurs. Posterior median margins of the 2nd paired lateral plates and the terminal plate separately with a pair of long angles. Echiniscus cavagnaroi Schuster et Grigarick, 1966 (Fig.2) One specimen were found in the area of 3*!200*!m altitude of Lijiang County. Body length 140*!μm. In the form of pattern of networks on the dorsal plates, without eyes. Three median plates of dorsum are not transversely divided. Posterior lateral margins of every two lateral plates with a pair of spiniform appendages. At the back of terminal plate with a pair of sculptures. Echiniscus migiurtinus Franceschi, 1957 (Fig.3) Two specimens were found in the area of 3*!200*!m altitude of Lijiang County. Body length 193.6*!μm.
