Pachycondyla
Panther Ants
Pachycondyla is a genus of ponerine ants found in the Neotropics. Following a major taxonomic revision by Schmidt & Shattuck (2014), the genus was drastically reduced from hundreds of species to eleven extant species, with many former members moved to revived genera. The genus now contains primarily Neotropical species distributed from the southern United States to northern Argentina. Some species, such as P. chinensis (Asian needle ant), have become invasive beyond their native ranges. The genus includes both ground-nesting and arboreal species, with some forming mutualistic relationships with plants.
Pseudomyrmecinae
big-eyed tree ants, big-eyed ants
Pseudomyrmecinae is a subfamily of slender, hyperoptic arboreal ants comprising three genera: Pseudomyrmex (~200 species, Neotropical), Tetraponera (~100 species, Palaeotropical), and Myrcidris (two species, South America). The subfamily originated in the Palaeotropics during the Cretaceous and later dispersed to South America, where it underwent significant diversification. At least twelve independent origins of obligate mutualisms with domatia-bearing plants have occurred within this group, making it the most diverse plant-occupying ant lineage worldwide.
Pseudomyrmex
Twig Ants, Acacia Ants
Pseudomyrmex is a genus of stinging ants in the subfamily Pseudomyrmecinae, comprising approximately 180-209 species distributed primarily in tropical and subtropical regions of the New World. The genus is characterized by large compound eyes, slender wasp-like bodies, and diurnal activity patterns. Most species are generalist twig nesters that inhabit hollow stems and dead wood, though several species have evolved obligate mutualistic relationships with myrmecophytic plants, most famously with bullhorn acacias (Acacia spp.). These mutualistic species provide aggressive defense of their host plants against herbivores and competing vegetation in exchange for nesting sites and specialized food sources.
