The xanthid genus Medaeops Guinot, 1967 currently contains seven species reported from the Indo-West Pacific region. However, only one species, Medaeops granulosus (Haswell, 1882), has been recorded from China seas and was once thought to be widespread in the Indo-West Pacific region. In this study, two species of the Medaeops granulosus species-group were identified during the analysis on Medaeops crabs from China seas. Medaeops japonicus (Rathbun, 1898), which had previously been considered a junior synonym of M. granulosus, is shown to be a distinct species that can be distinguished from M. granulosus by the lower first anterolateral tooth, the larger and concentrated granules on carapace dorsally, and the different shape of the male’s first gonopod. In addition, a new recorded species, Medaeops edwardsi Guinot, 1967, was reported from China seas for the first time. A molecular analysis was conducted to determine the status of each species, and an updated key for species of the genus Medaeops was provided.
