Dinoponera is a strictly South American genus of ant in the subfamily Ponerinae, commonly called tocandiras or giant Amazonian ants. [2] These ants are generally less well known than Paraponera clavata, the bullet ant, yet Dinoponera females may surpass 3–4 cm (1.2–1.6 in) in total body length, making them among the largest ants in the world.
Dinoponera australis has the widest known range of the Dinoponera.This species is found in the department of Santa Cruz in Bolivia, southern Brazil in the states of Mato Grosso, Goiás, Minas Gerais, São Paulo, Mato Grosso do Sul, Paraná, Santa Catarina and Rio Grande do Sul, eastern Paraguay in the departments of Itapúa, Alto Paraná and Guairá, as well as the province of Misiones in ...
Ponerinae, the ponerine ants, [2] is a subfamily of ants in the Poneromorph subfamilies group, with about 1,600 species in 47 extant genera, including Dinoponera gigantea - one of the world's largest species of ant. Mated workers have replaced the queen as the functional egg-layers in several species of ponerine ants.
Dinoponera lucida is a large queenless species of ant in the subfamily Ponerinae. The species, endemic to Brazil, is threatened by habitat destruction. Workers range from 27 to 30 mm in body length, which is slightly larger than the related species Dinoponera australis, but smaller than other large ants. Males are unknown.
Dinoponera gigantea is one of the world's largest species of ant. [4] The females of the species are larger than males, with lengths ranging from 3 to 4 centimetres (1.2 to 1.6 in). [ 5 ] The females are coal-black in color, while the much smaller males are dark red.
A photo of Dinoponera quadriceps showing key futures. Like other Dinoponera, Dinoponera quadriceps lacks a distinct queen caste and all individuals are morphologically similar and capable of reproduction. In Dinoponera quadriceps, dominance hierarchies tend to be relatively short where only a few individuals actively compete for reproduction. [6]
Doubt was raised by Kempf (1971) as to whether Dinoponera longipes was a valid species. Since few specimens have been collected from western Brazil a clinal variation in character form with Dinoponera gigantea or Dinoponera mutica was a possibility. Specimens from Brazil examined by Lenhart, Dash & MacKay (2013) showed no such integration.
A queen ant (formally known as a gyne) is an adult, reproducing female ant in an ant colony; she is usually the mother of all the other ants in that colony. Some female ants, such as the Cataglyphis , do not need to mate to produce offspring, reproducing through asexual parthenogenesis or cloning , and all of those offspring will be female. [ 1 ]
