This genus contains three described species: A. nidicola Mjoberg (Queensland), A. hillii Nicholls (south-western Australia), and A. inclusus Gay (restricted to a small sub-coastal area in mid- Western Australia).  All the species have a species-specific parasitic nesting relationship with either one of two species of the genus Coptotermes. They live in specific parts of the inner sections of Coptotermes nests, using as food the carton composing these sections, and are thus dependent on the host for food and shelter. They are not found in any other situation. The nests of host and parasite are separated and the two species are mutually hostile.
