Aphaenogaster is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species.[1] They occur worldwide except in South America south of Colombia, sub-Saharan Africa, and Antarctica.[2]

They are often confused with Pheidole or Pheidologeton. These two have major and minor workers, while Aphaenogaster has only a single worker caste. Pheidole has three-segmented clubs on its antennae, while Aphaenogaster has four segments and a larger body size. Pheidologeton has 11-segmented antennae, while the antennae in Aphaenogaster are 12-segmented.[3]

In Australia, they often build dense, conspicuous nests.[4] Nest entrances are generally funnel-shaped with diameters up to 4 cm, which resulted in the common name funnel ants. These nests can be a serious problem for golfers or on pastures and unsealed airstrips, because the fragile surface easily collapses under pressure.[3] Where it occurs, Aphaenogaster bioturbation is an important soil and landscape process.[4]

Aphaenogaster ants probably get most of their food from tended aphids on the roots of plants, which explains that they are rarely seen on the surface. The funnel-shaped openings could play a role in trapping arthropods, which are also eaten.[3]
