Indo-Australian Region: Borneo, Indonesia, Malaysia. Oriental Region: Thailand.

Biology
Soldiers have specialized morphological traits that allow two distinct functions: (1) trophic eggs are produced in ovaries (6 ovarioles) that are the same as in queens (Gobin & Ito 2000); (2) mandibles are modified in shape to crush fig seeds, just as in queens. A. ferox colonies (n=49) have 25±11 workers and 2.6±1.5 soldiers (Gobin & Ito 2000).
