Summary

Pseudomyrmex is a diverse genus of stinging ants known for their large eyes and slender bodies, predominantly found in tropical and subtropical regions of the Americas, with species having specialized nesting habits, including mutualistic relationships with certain tree species.

Physical Characteristics

Worker ants have 12-segmented antennae; mandibles with a proximal tooth on the basal margin; and large, elongate eyes that are more than 1.5 times as long as wide.

Identification Tips

Look for the large eyes and slender body shape characteristic of the genus.

Habitat

Most species nest in dead twigs or stems of woody plants, with some specializing in live plant domatia, particularly in acacia species.

Distribution

Predominantly Neotropical; a few species occur in the Nearctic region.

Ecosystem Role

Many species act as mutualists with specific plant species, helping with protection against herbivores and in some cases aiding in pollination.
