Odontomachus pseudobauri is an extinct species of ant in the subfamily Ponerinae known from one possibly Miocene fossil found on Hispaniola.

The specimen was collected from an undetermined amber mine in fossil-bearing rocks of the Cordillera Septentrional mountains of northern Dominican Republic.

The holotype fossil was first studied by entomologist Maria L. De Andrade of the University of Basle with her 1994 type description of the new species being published in the journal Stuttgarter Beiträge zur Naturkunde.

[1] The modern species is found in the Galápagos Islands, tropical regions of South and Central America, and most of the West Indies except the Bahamas and Cuba.

[4] The O. pseudobauri worker is approximately 9.28 mm (0.37 in) in length, and has a shining exoskeleton of orange along the body, reddish head and mandibles, and brownish tones on the gaster.

The smooth exoskeleton has tiny punctuation found across the rear and sides of the head, in the front areas of the antennae depressions, and over the gaster.
