The meat ant, also known as the gravel ant or southern meat ant, is a species of ant endemic to Australia. A member of the genus Iridomyrmex in the subfamily Dolichoderinae, it was described by British entomologist Frederick Smith in 1858. The meat ant is associated with many common names due to its appearance, nest-building behaviour and abundance, of which its specific name, purpureus, refers to its coloured appearance. It is among the best-known species of ant found throughout Australia; it occurs in almost all states and territories except for Tasmania. Its enormous distribution, aggression and ecological importance have made this ant a dominant species.
Ochetellus glaber is a species of ant native to Australia. A member of the genus Ochetellus in the subfamily Dolichoderinae, it was described by Austrian entomologist Gustav Mayr in 1862. Aside from Australia, O. glaber has been introduced to a number of countries, including China, India, Japan, New Zealand, the Philippines and the United States, where it has established itself in Hawaii and Florida. It has been found on Lord Howe Island, New Caledonia, Norfolk Island, Réunion and the Solomon Islands. Compared with other ants, O. glaber is a small species, with workers measuring 2–3 mm (0.079–0.118 in). Males are the smallest at 1.6 mm (0.063 in), while the queens measure 5.2–5.5 mm (0.20–0.22 in). The ant's colour ranges from brown to black.
Iridomyrmex bicknelli is a species of ant belonging to the genus Iridomyrmex. The species is distributed in every single state and territory in Australia. Iridomyrmex bicknelli was described by Emery in 1898.
Eldermyrmex is an extinct genus of ant in the Formicidae subfamily Dolichoderinae. The genus contains a single described species Eldermyrmex oblongiceps. Eldermyrmex is known to be from the Baltic Amber.
Yantaromyrmex is an extinct genus of ants first described in 2013. Members of this genus are in the subfamily Dolichoderinae of the family Formicidae, known from Middle Eocene to Early Oligocene fossils found in Europe. The genus currently contains five described species, Y. constrictus, Y. geinitzi, Y. intermedius, Y. mayrianum and Y. samlandicus. The first specimens were collected in 1868 and studied by Austrian entomologist Gustav Mayr, who originally placed the fossils in other ant genera until the fossils were reviewed and subsequently placed into their own genus. These ants are small, measuring from 4 to 6 mm in length and can be characterized by their trapezoidal shaped head-capsules and oval compound eyes that are located slightly to the rear of the capsules midpoint, with no known ocelli present.

Iridomyrmex elongatus is a species of ant in the genus Iridomyrmex, described by Heterick and Shattuck in 2011. Its biology is almost unknown, but the distribution of the ant extends from Western Australia and into the Northern Territory.
Iridomyrmex hesperus is a species of ant in the genus Iridomyrmex. Described by Shattuck in 1993, not much is known about the ant, other than its populations are mostly confined in Western Australia.
Iridomyrmex innocens is a species of ant in the genus Iridomyrmex. Described by Forel in 1907, the species is endemic to Australia, mainly confined in Western Australia, but the species is more common in areas with higher rainfalls within the Darling Ranges.
Iridomyrmex mayri is a species of ant in the genus Iridomyrmex. Described by Forel in 1915, the species is endemic to Australia, these ants commonly nests under stones and rotting logs, and forage on tree trunks. The species also tends to larvae of Jalmenus evagoras butterflies.
Iridomyrmex minor is a species of ant in the genus Iridomyrmex. Described by Forel in 1915, the ant is common in Western Australia, South Australia, Northern Territory and Queensland, and it is unlikely there are existing colonies in more southern Australian states. Nests have been found under bark, and is among the most likely ant to be encountered by the general public.
Iridomyrmex mjobergi is a species of ant in the genus Iridomyrmex. Described by Forel in 1915, the species is among the most common of the genus, endemic to all states and territories in Australia, and even extends into New Guinea. Workers are not usually aggressive, and they have been observed foraging for foods like nectar and honeydew.
