Diacamma rugosum, also known as the Bornean queenless ant, is a species of ant of the subfamily Ponerinae. It is found in many countries throughout Southeast Asia. 20 subspecies are recognized. [1]

Contents

D. rugosum is noted for being one of the only species of ants to completely lack a queen caste. Reproduction is done entirely by workers, with all workers being fertile upon birth. [2] However, reproduction is kept strictly under control in the nest, with only one dominant female, or gamergate, laying all of the eggs. The gamergate will render workers sterile by mutilating their vestigial wing buds as soon as they pupate. [3] These infertile workers, called callows, will remain loyal to the present gamergate and allow her to exercise control over the rest of the workers. [4] This works to reduce colony infighting as it makes usurpation virtually impossible, and the only time the gamergate is replaced is if she dies naturally.

Ponerinae Subfamily of ants

Ponerinae 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. In such queenless species, the reproductive status of workers can only be determined through ovarian dissections. Ponerinae is a subfamily of ants within the family of Formicidae. These ants typically nest in soil, forest litter, or rotting logs, and are predacious. They primarily prey on isopods. They mostly live in small colonies of up to 200 workers. They can be found mostly in tropical environments, but have been found in southeastern Canada and New York. Female workers have twelve segmented antennae, whereas male workers have 13 segmented antennae.

<i>Cataglyphis</i> Genus of ants

Cataglyphis is a genus of ant, desert ants, in the subfamily Formicinae. Its most famous species is C. bicolor, the Sahara Desert ant, which runs on hot sand to find insects that died of heat exhaustion, and can, like other several other Cataglyphis species, sustain body temperatures up to 50°C. Cataglyphis is also the name of an autonomous rover that won the NASA Sample Return Robot Centennial Challenge inspired by the navigation approaches used by desert ants.

<i>Crematogaster</i> Genus of ants

Crematogaster is an ecologically diverse genus of ants found worldwide, which are characterised by a distinctive heart-shaped gaster (abdomen), which gives them one of their common names, the Saint Valentine ant. Members of this genus are also known as cocktail ants because of their habit of raising their abdomens when alarmed. Most species are arboreal. These ants are sometimes known as acrobat ants.

<i>Plagiolepis</i> Genus of ants

Plagiolepis is an ant genus of the formic acid-producing subfamily Formicinae. The genus is found in tropical and temperate regions of the Old World.

<i>Harpegnathos</i> Genus of ants

Harpegnathos is a small ponerine genus of ants found in South and Southeast Asia. They are notable for their jumping ability, complex colony structure, and large to very large workers easily identifiable by their long mandibles and large eyes.

<i>Amblyopone</i> Genus of ants

Amblyopone is a genus of 10 species of ants, found in Australia, New Caledonia, New Guinea and New Zealand. Ants of this genus possess the gamergate, meaning workers are able to reproduce within a colony lacking a queen.

<i>Diacamma</i> Genus of ants

Diacamma is a genus of queenless ants sometimes known as Asian bullet ants, belonging to the subfamily Ponerinae. It is distributed from India to Australia and contains about 24 species.

<i>Platythyrea</i> Genus of ants

Platythyrea is a genus of predaceous ants in the subfamily Ponerinae and the sole member of the tribe Platythyreini.

<i>Rhytidoponera</i> Genus of ants

Rhytidoponera is a large genus of ants in the subfamily Ectatomminae. The genus is known from Australia and Melanesia, with New Caledonia as the most eastern limit.

Gamergate (ant) Reproductively viable female worker ant

A gamergate is a mated worker ant that can reproduce sexually, i.e., lay fertilized eggs that will develop as females. In the vast majority of ant species, workers are sterile and gamergates are restricted to taxa where the workers have a functional sperm reservoir ('spermatheca'). In some species, gamergates reproduce in addition to winged queens, while in other species the queen caste has been completely replaced by gamergates. In gamergate species, all workers in a colony have similar reproductive potentials, but as a result of physical interactions, a dominance hierarchy is formed and only one or a few top-ranking workers can mate and produce eggs. Subsequently however, aggression is no longer needed as gamergates secrete chemical signals that inform the other workers of their reproductive status in the colony.

Worker policing Eusocial hymnopteran behavior where worker females destroy or remove eggs laid by other workers, in order to ensure that the queens offspring will be successful

Worker policing is a behavior seen in colonies of social hymenopterans whereby worker females eat or remove eggs that have been laid by other workers rather than those laid by a queen. Worker policing ensures that the offspring of the queen will predominate in the group. In certain species of bees, ants and wasps, workers or the queen may also act aggressively towards fertile workers. Worker policing has been suggested as a form of coercion to promote the evolution of altruistic behavior in eusocial insect societies.

<i>Podomyrma</i> Genus of ants

Podomyrma is a genus of ants in the subfamily Myrmicinae.

<i>Carebara</i> Genus of ants

Carebara is a genus of ants in the subfamily Myrmicinae. It is one of the largest myrmicine genera with more than 200 species distributed worldwide in the tropics and the Afrotropical region. Many of them are very tiny cryptic soil and leaf litter inhabitants. They nest in rotten wood to which the bark is still adherent in the Afrotropical region, or may be lestobiotic nesting near other ant species. Some species are known to exist parasitically within termite nests. Little is known about the biology of the species. However, they are notable for the vast difference in size between queens and workers.

<i>Pseudolasius</i> Genus of ants

Pseudolasius is a genus of ants in the subfamily Formicinae. The genus is known from southern Asia to northern Australia, where it appears to be restricted to tropical areas.

Camponotus irritans is a species of carpenter ant. It is found in many Asian and Oceanian countries.
