Aenictus aitkenii

This species is so far known only from India and Sri Lanka.

Identification
This species is similar to A. aratus (with which it has been treated as a junior synonym) and A. nesiotis but differs in having a broader head (cephalic index > 87 versus CI < 88 in A. nesiotis), and broader and more bulbous petiole and postpetiole (both are narrower in A. aratus and A. nesiotis). The scape is also relatively longer than in the others (scape index > 115 versus < 115). It is similar to A. levior in the shape of the head but differs in having longer scapes (Shattuck, 2008).
