Ants in this predominantly Neotropical genus nest in hollow dead twigs and other preformed plant cavities. Two species occur in California: P.apache Creighton is widespread at middle and low elevations within the California floristic province, often nesting in branches of manzanita ( Arctostaphylos ), while P. pallidus (F. Smith) is confined to southern California.

Pseudomyrmex is a genus of stinging, wasp-like ants in the subfamily Pseudomyrmecinae. They are large-eyed, slender ants, found mainly in tropical and subtropical regions of the New World.
Pseudomyrmex is predominantly Neotropical in distribution, but a few species are known from the Nearctic region.[4] Most species are generalist twig nesters, for instance, Pseudomyrmex pallidus may nest in the hollow stems of dead grasses, twigs of herbaceous plants, and in dead, woody twigs.[4] However, the genus is best known for several species that are obligate mutualists with certain species of Acacia.[5] Other species have evolved obligate mutualism with other trees; for example Pseudomyrmex triplarinus is obligately dependent on any of a few trees in the genus Triplaris.[6][7]
