Aenictus is the most species-rich genus of army ants in the subfamily Dorylinae and one of the most species rich ant genera in China and the World. In this paper a new species of the Aenictus ceylonicus group, Aenictus hoelldobleri Staab sp. n., is described and illustrated based on the worker caste. The new species occurs in the subtropical forests of South-East China and is probably most closely related to A. wudangshanensis Wang, 2006 and A. henanensis Li & Wang, 2005 from which A. hoelldobleri can be distinguished by the shape of the subpetiolar process. The new species also resembles A. lifuiae Terayama 1984 and A. thailandianus Terayama & Kubota, 1993 but clearly differs in various features of the cuticular sculpture. A key to the Chinese species of the A. ceylonicus group based on the worker caste is provided. Several new locality records, among them the first records of A. thailandianus and A. watanasiti Jaitrong & Yamane, 2013 from China, are given.
