Harpegnathos
''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. Taxonomy The genus was established by Thomas C. Jerdon in 1851 to house the single species ''Harpegnathos saltator'', found in India. Believing that the name was unavailable due to homonymy, Smith (1858) incorrectly erected the unnecessary replacement name ''Drepanognathus'' (now a synonym of ''Harpegnathos''). For some time, both names were used in publications by other authors until the original name was restored. The most recent species was described in 1963, making the total number of ''Harpegnathos'' species seven, with an additional four described subspecies. The genus is closely related to the other genera in its tribe, Ponerini, and is probably a sister to all Ponerini. Multifunctional mandibles The ant's mandible exhibits ...

Harpegnathos Saltator
''Harpegnathos saltator'', sometimes called the Indian jumping ant or Jerdon's jumping ant, is a species of ant found in India. They have long mandibles and have the ability to leap a few inches. They are large-eyed and active predators that hunt mainly in the early morning. The colonies are small and the difference between workers and queens is very slight. Subspecies *''H. s. cruentatus'' (Smith, 1858) *''H. s. taprobanae'' Forel, 1909 Habits Unlike other ants, they are seen singly or in small groups and their colonies consist of very few individuals. They are also unusual amongst ants in that the queen-worker difference is very limited and some workers can mate and lay fertilized eggs just like the queen. These workers are termed gamergates. New colonies are founded independently by single queens, and on aging, they are replaced by several gamergates. The gamergates copulate with males from their own colonies, and being inbred, are related to the original founding queen. Co ...

Harpegnathos Venator
''Harpegnathos venator'' is a species of ant found in South Asia, South and Southeast Asia in northern India and parts of Burma. Subspecies *''H. v. chapmani'' Donisthorpe, 1937 *''H. v. rugosus'' (Mayr, 1862) Description The following is a taxonomic description of the ant based on Charles Thomas Bingham, C. T. Bingham's ''The Fauna of British India, Including Ceylon and Burma'' (Hymenoptera, Volume 2): * Worker: Black; mandibles, clypeus, antennal carinae, and legs brownish yellow, antennae chestnut, apex of the abdomen rusty; head and thorax closely coarsely cribrate punctate ; abdomen finely densely reticulate punctate, opaque, with some large shallow punctures. Head, thorax and abdomen covered with rather sparse, short, erect pale hairs ; pubescence minute but fairly plentiful, to be seen only in certain lights. For the rest the characters of the genus. * Queen: Similar to the worker, but the abdomen with long oblong punctures, the ocelli in the middle of the front. Thorax ...

Ant Genera
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens" (gynes). The colonies are described as superorganisms because the ants a ...

Gamergate (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 (usually upon the death of the original foundress), 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 (usually with foreign males) 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. Depending on the species, there can be one gamergate per colony (monogyny) or seve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponerinae
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. Description and identification They are most easily identified from other subfamilies by possessing a single-node petiole with a constriction before the second gastral segment. They are rare examples of stinging ants. In addition to the sting, they can also be characterized by a single segmented petiole and the constriction of the first and second segment of the gaster. They can also be identified by the shape of their head. Female workers have twelve segmented antennae, whereas male workers have 13 segmented antennae. Behavior These ants typically nest in soil, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
