Pseudomyrmex ejectus

Gillette et al. (2015), in a Chaipas, Mexico field study of twig-nesting ants in coffee plants, found P. ejectus occupied 57% of all occupied twig-nests above 1100 m. In Florida, this species is the host for the workerless parasite.

Distribution based on Regional Taxon Lists
Nearctic Region: United States. Neotropical Region: Bolivia, Brazil, Costa Rica, Greater Antilles, Guatemala, Mexico.
