Material examined.

Two syntype worker images examined, AntWeb, CASENT0916847 & CASENT0915166, photos by Will Ericson.

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.
