Aphaenogaster is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species.[1] They occur worldwide except from South America and Southern Africa.[citation needed]

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 a 3-segmented club on its antenna, while Aphaenogaster has four segments and a larger body size. Pheidologeton has an 11-segmented antenna, while the antenna in Aphaenogaster is 12-segmented.[2]

In Australia, they often build dense, conspicuous nests.[3] Nest entrances are generally funnel-shaped with diameters of 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.[2] Where it occurs, Aphaenogaster bioturbation is an important soil and landscape process.[3]

Aphaenogaster probably gets most of its 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.[2]
