The Leptotyphlopidae are a family of snakes found in North America, South America, Africa, & Asia. All are fossorial and adapted to burrowing, feeding on ants and termites. Two subfamilies are recognized.
Odontomachus bauri is a species of ponerinae ant known as trap jaw ants. The trap jaw consists of mandibles which contain a spring-loaded catch mechanism.
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°.
Odontomachus brunneus is a species of ant in the subfamily Ponerinae, found in the southeastern United States, parts of Central America, and the West Indies.
Sphecomyrminae is an extinct subfamily of ants in family Formicidae known from a series of Cretaceous fossils found in North America, Europe, and Asia. Sphecomyrminae contains ten genera, divided into two tribes, Haidomyrmecini and Sphecomyrmini. The tribe Haidomyrmecini contains the five genera Ceratomyrmex, Haidomyrmex, Haidomyrmodes, Haidoterminus and Linguamyrmex, while Sphecomyrmini contains Baikuris, Cretomyrma, Dlusskyidris, Sphecomyrma, and Zigrasimecia. The genus Sphecomyrmodes was formerly placed into Sphecomyrmini; however, in 2016, it was made a synonym of the stem group genus Gerontoformica, which is considered incertae sedis in Formicidae.
Mystrium is a rare genus of ants in the subfamily Amblyoponinae. First described by Roger (1862) with the description of the queen of M. mysticum, the genus contains 14 species, all of which occur in the rainforests of the Old World with over half of the species endemic to the Malagasy region. The snapping jaw of one species, Mystrium camillae, is the fastest animal movement on record.
Daceton is a Neotropical genus of ants in the subfamily Myrmicinae. The genus contains only two species: D. armigerum, the most studied species, distributed throughout northern South America, and D. boltoni, known from Brazil and Peru.
Daceton armigerum is a Neotropical species of arboreal ants, distributed throughout northern South America. D. armigerum combines several traits generally noted in some other arboreal ants i.e., populous colonies, large and/or polydomous nests, intra- and interspecific aggressiveness, trophobiosis, and capturing prey by spread-eagling them.
Haidomyrmodes is an extinct genus of ant in the formicid subfamily Sphecomyrminae, and is one of only five genera placed in the tribe Haidomyrmecini. The genus contains a single described species, Haidomyrmodes mammuthus. Haidomyrmodes is known from several Middle Cretaceous fossils which have been found in Europe.
Haidoterminus is an extinct genus of ant in the Formicidae subfamily Sphecomyrminae, and is one of only five genera placed in the tribe Haidomyrmecini. The genus contains a single described species Haidoterminus cippus and is known from one Late Cretaceous fossil which has been found in North America.
Haidomyrmex is an extinct genus of ants in the formicid subfamily Sphecomyrminae, and is one of only five genera placed in the tribe Haidomyrmecini. The genus contains three described species Haidomyrmex cerberus, Haidomyrmex scimitarus, and Haidomyrmex zigrasi. All three are known from single Late Cretaceous fossils which have been found in Asia. H. cerberus is the type species and Haidomyrmex the type genus for the tribe Haidomyrmecini.
Acanthognathus poinari is an extinct species of ant in the subfamily Myrmicinae known from a single possibly Miocene fossil found on Hispaniola. A. poinari is the first species of the ant genus Acanthognathus to have been described from fossils found in Dominican amber and is one of several species of Acanthognathus found in the Greater Antillies.
Cananeuretus is an extinct genus of ant in the Formicidae subfamily Aneuretinae, and is one of two Cretaceous genera of the subfamily. The genus contains a single described species Cananeuretus occidentalis and is known from one Late Cretaceous fossil which has been found in North America.
Ceratomyrmex is an extinct genus of ant in the Formicidae subfamily Sphecomyrminae, and is one of only five genera placed in the tribe Haidomyrmecini. The genus contains a single described species Ceratomyrmex ellenbergeri and is known from several Late Cretaceous fossils which have been found in Asia.
Odontomachus assiniensis is a species of ponerinae ant known as a trap-jaw ant. The trap-jaw mechanism consists of mandibles which spring shut when triggered. This ant was first described in 1892 by the Italian entomologist Carlo Emery. The type locality is the Ivory Coast, where the coastal site of Assini, in the southeast, gIves the specific name assiniensis, "of Assini".
Linguamyrmex is an extinct genus of ant in the formicid subfamily Sphecomyrminae, and is one of only five genera placed in the tribe Haidomyrmecini. The genus contains a single described species, Linguamyrmex vladi, and is known from several Late Cretaceous fossils which have been found in Asia.
Anochetus daedalus is a species of trap-jaw ant in the subfamily Ponerinae. It can be found from Western Ghats in India.
Formica archboldi is a species of ant in the family Formicidae. They are known for their abnormal behavior, which includes the collection and storage of Odontomachus (trap-jaw) ant skulls.
