Pogonomyrmex abdominalis Santschi; Bolton, 1995. Revived combination in Pogonomyrmex.
Etymology: The specific epithet, abdominalis (from Latin, abdomen- = abdomen), appears to be derived from the enlarged postpetiole on this species, which Santschi described as wider than long for the worker and even larger and more pronounced in the queen.
