Pseudomyrmex pallidus is a species of ant found in the Nearctic realm with an extensive range throughout the southern United States to Central America.

Mated queens in the nest can be identified by scars on their thorax where the wings were previously attached.

[citation needed] Nests of this species are found in the hollow stems of dead grasses.

Although they show a preference for herbaceous plants, nests have also been found in the dead stems of woody twigs.

However, males appear to only be produced during the summer and the fall seasons, as they are absent from nests collected in the winter.
