Micaria bonneti Schenkel, 1963, a species known only from China, is reported from Mongolia. Conspecificity of this species with specimens from Hubei Province and the central part of Inner Mongolia (type locality) is doubtful. M. mongunica Danilov, 1997, a species known by the holotype female from Western Tuva, is most likely a junior synonym of M. bonneti. Erroneous data about the type locality of M. bonneti is corrected. The epigyne of M. bonneti is illustrated in detail, and its structure is discussed.
