Odontoponera
''Odontoponera'' is a small Southeast Asia genus of ants in the subfamily Ponerinae. Description Workers are medium in size (9–12 mm); queens are similar to workers but larger (11–13 mm) and winged. Distribution Its two species are restricted to Southeast Asia, distributed from India in the west to the Philippines in the east, and from southern China further south down to Indonesia. The ants are locally abundant, with ''O. denticulata'' having the widest distribution of the species, from mainland Asia to the Philippines and Sundaland; ''O. transversa'' is found from the Malay Peninsula south to the islands of Sundaland. Taxonomy ''Odontoponera'' was established by Mayr (1862) to house the species ''Ponera denticulata'' (now ''Odontoponera denticulata''), placing it in the subfamily Ponerinae. ''O. denticulata'' was later synonymized with ''O. transversa'', but was revived as a species by Yamane (2009). Molecular phylogeny by Schmidt's (2013) placed the genus i ...

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] |

Sundaland
Sundaland (also called Sundaica or the Sundaic region) is a biogeographical region of South-eastern Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower. It includes Borneo, Java, and Sumatra in Indonesia, and their surrounding small islands, as well as the Malay Peninsula on the Asian mainland. Extent The area of Sundaland encompasses the Sunda Shelf, a tectonically stable extension of Southeast Asia's continental shelf that was exposed during glacial periods of the last 2 million years. The extent of the Sunda Shelf is approximately equal to the 120-meter isobath. In addition to the Malay Peninsula and the islands of Borneo, Java, and Sumatra, it includes the Java Sea, the Gulf of Thailand, and portions of the South China Sea. In total, the area of Sundaland is approximately 1,800,000 km2. The area of exposed land in Sundaland has fluctuated considerably during the past recent ...

Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of papers f ...

Ponera
''Ponera'' is a genus of ponerine ants. The name is the Latinized form (') of the Ancient Greek ' (, 'wicked, wretched'). Description Workers are very small to small in size (1–4 mm); queen are similar to workers but winged. This genus is very similar to ''Cryptopone'', ''Hypoponera'' and ''Pachycondyla''. Biology ''Ponera'' nests contain less than 100 workers in protected places on the ground, most often in the soil or in cracks, rotten wood, under bark or moss on rotten logs. Distribution ''Ponera'' is known from the Holarctic, Samoa, New Guinea and Australia.

Odontomachus
''Odontomachus'' is a genus of ants commonly called trap-jaw ants found in the tropics and subtropics throughout the world. Overview Commonly known as trap-jaw ants, species in ''Odontomachus'' have a pair of large, straight mandibles capable of opening 180°. These jaws are locked in place by an internal mechanism, and can snap shut on prey or objects when sensory hairs on the inside of the mandibles are touched. The mandibles are powerful and fast, giving the ant its common name. The mandibles either kill or maim the prey, allowing the ant to bring it back to the nest. ''Odontomachus'' ants can simply lock and snap their jaws again if one bite is not enough, or to cut off bits of larger food. The mandibles also permit slow and fine movements for other tasks such as nest building and care of larvae. The ants were also observed to use their jaws as a catapult to eject intruders or fling themselves backwards to escape a threat. The larvae of trap-jaw ants are remarkable in b ...

Molecular Phylogeny
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.
