Megalomyrmex nocarina

Little is known about the biology of .

Identification
Boudinot et al. (2013) - Worker Uniquely identifiable among Central American Megalomyrmex by the following combination of characters: (1) mandible with 7–10 minute denticles subtending two large apical teeth; (2) katepisternum smooth and shining; (3) occipital carina visible in full-face view; (4) foraminal carina usually absent; (5) postpetiole extremely robust, weakly compressed anteroposteriorly; (6) postpetiolar sternum bulging, minutely dentate anteriorly.

Specimens from Panama have a foraminal carina, contradicting the namesake diagnostic character state. The species is additionally separated from other species in the mondabora complex by its long, thin, posterior clypeal portion.
