Myrmoteras is a genus of ants in the subfamily Formicinae and the sole member of the tribe Myrmoteratini.

[2] They have enormous eyes, a character found in other ancient genera, and extremely elongated mandibles with eight to 16 teeth.

[3] 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.
