Myrmoteras
''Myrmoteras'' is a genus of ants in the subfamily Formicinae and the sole member of the tribe Myrmoteratini. They have enormous eyes, a character found in other ancient genera, and extremely elongated mandibles with eight to 16 teeth. These work as trap-jaws and can open up to 270°. Description While the elongated mandibles look superficially similar to those of the basal ''Myrmecia'', the mechanism is, as a whole, totally dissimilar and is rather convergent to that of the ponerine genera ''Anochetus'' and ''Odontomachus'', and the myrmicine ''Strumigenys''. The trigger mechanism of the trap-jaw-like mandibles of ''Myrmoteras'' consists of two hairs. Other trap-jawed genera are '' Daceton'', '' Acanthognathus'', '' Orectognathus'', '' Microdaceton'', and '' Epitritus''. Distribution ''Myrmoteras'' occurs in the Indo-Malayan region.Creighton, William S. (1930): A Review of the Genus ''Myrmoteras'' (Hymenoptera, Formicidae).

Formicinae
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development. Formicines retain some primitive features, such as the presence of cocoons around pupae, the presence of ocelli in workers, and little tendency toward reduction of palp or antennal segmentation in most species, except subterranean groups. Extreme modification of mandibles is rare, except in the genera '' Myrmoteras'' and '' Polyergus''. However, some members show considerable evolutionary advancement in behaviors such as slave-making and symbiosis with root-feeding hemipterans. Finally, all formicines have very reduced stings and enlarged venom reservoirs, with the venom gland, specialized (uniquely among ants) for the production of formic acid. All members of the Formicinae "have a one-segmented petiole in the form of a vertical scale". Identification Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of th ...

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 ...

Java
Java (; id, Jawa, ; jv, ꦗꦮ; su, ) is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's most populous island, home to approximately 56% of the Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast. Many of the best known events in Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally. Four of Indonesia's eight UNESCO world heritage sites are located in Java: Ujung Kulon National Park, Borobudur Temple, Prambanan Temple, and Sangiran Early Man Site. Formed by volcanic eruptions due to geologic subduction of the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borneo
Borneo (; id, Kalimantan) is the List of islands by area, third-largest island in the world and the largest in Asia.

Epitritus
''Strumigenys'' is a genus of ants in the subfamily Myrmicinae. Biology ''Strumigenys'' form small nests in soil, under or between rocks, or in and under logs or under cattle dung. Some species nest in association with other ants such as '' Bothriomyrmex mayri'' or ''Rhytidoponera metallica''. Although they are normally slow moving, they can run quickly when disturbed. ''S. xenos'' is a permanent social parasite, which forms no workers and lives in the nests of its host ''S. perplexa''. Most species specialize in the hunt of springtails, and the others eat other soft-bodied arthropods.Australian Ants OnlineGenus ''Strumigenys''/ref> Distribution ''Strumigenys'' is found throughout the tropics and subtropics. 18 species are known from Australia.
