The present paper deals with thirteen species of the genus Clubiona from Inner Mongolia, China. Four new species are described: C. falcate sp. nov., C. haupti sp. nov., C. qini sp. nov., and C. semicircularis sp. nov. Six species are newly recorded from Inner Mongolia: C. interjecta L. Koch, 1870; C. irinae Mikhailov, 1991; C. neglecta O. P.-Cambridge, 1862; C. odesanensis Paik, 1990; C. papillata Schenkel, 1936; and C. phragmitis C. L. Koch, 1843. The specimen previously identified in the region as C. hedini Schenkel, 1936 is assigned to C. jucunda (Karsch 1879). C. xilinensis Yin, Yan, Gong & Kim, 1996 is newly synonymized with C. riparia (L. Koch 1866). A redescription is made for C. japonicola Boesenberg & Strand, 1906, which has been reported briefly but has not been illustrated in the region previously. A key to all of these species is presented.
