A. hilli was described by Clark (1928) from a single male collected at Malanda, Queensland. There are numerous males in ANIC which are morphologically similar to the type of A. hilli. Unfortunately none are associated with workers. In addition, the remaining described Australian species are all worker-based and without associated males. This makes it impossible to positively associate A. hilli with any of these other species. Distribution patterns give little clue as to the association either as Aenictus aratus, A. nesiotis, A. prolixus and A. turneri all occur in the general area of the type locality of A. hilli. Thus there is currently insufficient information to associate A. hilli, or any of these other males, with any of the worker-based species. As a result A. hilli is here treated as a valid species and these additional males tentatively associated with it until such time that worker-associated males or fresh material suitable for molecular analysis can be secured.
