Recognition and discussion. After observation of the syntype worker images of A. risii (Fig. 8 ) and A. gracilis (Fig. 11 ) from AntWeb, we find that there are clear differences between them: 1) inner margin of mandibles has no denticles in the worker of A. gracilis , but possesses several distinct denticles in the worker of A. risii ; 2) the maximum diameter of eye is much larger than the maximum width of mandible in the worker of A. gracilis , but smaller than or just equal to maximum width of mandible in the worker of A. risii ; 3) pronotal sides distinctly striate in the worker of A. gracilis , but smooth and shining in the worker of A. risii . Therefore, the status of A. gracilis is restored from the synonymy of A. risii here. Distribution. Known from Indonesia (Java).
