Azteca eumeces is an extinct species of ant in the subfamily Dolichoderinae known from possibly Miocene[1] fossils found on Hispaniola.

A. eumeces is one of only two species in the ant genus Azteca to have been described from fossils, both found in Dominican amber.

[2] When described Azteca eumeces was known from approximately thirty nine fossil insects which are solitary or group inclusions in transparent chunks of Dominican amber.

[2] The amber was produced by the extinct Hymenaea protera, which formerly grew on Hispaniola and across northern South America up to southern Mexico.

The fossils were first studied by entomologist Edward O. Wilson of the Harvard University with his 1985 type description of the new species being published in the journal Psyche.
