Pseudomyrmex apache
Apache Twig Ant
Pseudomyrmex apache is a species of twig ant in the subfamily Pseudomyrmecinae. It is native to the southwestern United States and Mexico, with unconfirmed reports from Florida. The species is characterized by its golden yellow coloration and wasp-like body form typical of the genus. Like other Pseudomyrmex species, it has notably large compound eyes relative to body size.
Pseudomyrmex cubaensis
Cuban Twig Ant
Pseudomyrmex cubaensis is a species of twig ant in the family Formicidae. As a member of the genus Pseudomyrmex, it exhibits the characteristic slender, wasp-like body form and large compound eyes typical of this group. The species was originally described from Cuba and has since been recorded across the Caribbean and parts of South America. Like other Pseudomyrmex species, it is associated with arboreal habitats, particularly woody vegetation.
Pseudomyrmex gracilis
graceful twig ant, Mexican twig ant, slender twig ant, elongated twig ant
Pseudomyrmex gracilis is a large, slender ant species characterized by wasp-like appearance and rapid, frenetic movement. Workers measure 8–10 mm and display distinctive bi-coloration: dark head and gaster contrasting with dull orange antennae, mouthparts, thorax, and legs. The species is native to Mexico and arid regions of the southern United States, with introduced populations established in Florida and Hawaii. It has been documented as an invasive species in the Florida Keys, where it impacts native ecosystems.
Pseudomyrmex pallidus
Pallidus-group Twig Ants
Pseudomyrmex pallidus is a small, slender ant species native to the Nearctic and Neotropical realms, with an extensive range from the southern United States through Central America and into South America. Workers are monomorphic and exhibit variable coloration from yellow to orange or brown. The species nests exclusively in hollow stems of dead grasses and woody twigs, typically at the interface of grassy and wooded habitats. Colonies are facultatively polygynous and polydomous, containing 1–15 queens and 20–200 workers.
Pseudomyrmex seminole
Seminole Twig Ant
Pseudomyrmex seminole is a species of twig ant described by Ward in 1985. The common name references the Seminole people of Florida, where this species occurs. Like other members of the genus Pseudomyrmex, it exhibits the characteristic elongate, wasp-like body form and notably large compound eyes that distinguish this group from most other ants. The species belongs to a diverse Neotropical genus containing over 200 species, many of which are associated with woody vegetation.
