Review of the ant genus Anochetus Mayr, 1861 (Hymenoptera, Formicidae) from China, with revival of the valid status of Anochetus gracilis

Eight species of the ant genus Anochetus are recognized in China: A. graeffei Mayr, A. lanyuensis Leong et al., A. longus sp. n., A. madaraszi Mayr, A. mixtus Radchenko, A. medogensis sp. n., A. risii Forel, A. subcoecus Forel. A. taiwaniensis Terayama, 1989 is proposed as a junior synonym of A. risii Forel, 1900. Anochetus gracilis Karavaiev, 1925 is restored from synonymy of A. risii. A key based on the worker caste is provided for the Chinese species.
