Acanthognathus is a genus of ants that are found in tropical Central and South America.[2] There are 7 living species and 1 extinct species, Acanthognathus poinari, known only from fossil records.[3]

Description

They are reddish in colour and have long trap-jaws that can be compared to those of Odontomachus. These predatory ants live in small colonies that typically consist of less than 30 adults.[2]
Taxonomy

The genus was established by Mayr (1887) to house the species A. ocellatus, described from a single worker found in Brazil.[4]

Mistakenly, the name Acanthognathus was re-used by German ichthyologist G. Duncker in 1912 for a genus of syngnathid fish,[5] but that is invalid as it is a junior homonym.[6] These are now placed in either Dunckerocampus or Doryrhamphus, as the former sometimes is considered a subgenus of the latter.[7][8] To further confuse, a genus of nemesiid spiders, Acanthogonatus, is frequently misspelled Acanthognathus.
