Pheidole barbata
Bearded Big-headed Ant
Pheidole barbata is a species of big-headed ant in the genus Pheidole, first described by Wheeler in 1908. The common name "Bearded Big-headed Ant" refers to distinctive pilosity characteristic of this species. As with other members of its hyperdiverse genus, it exhibits the characteristic dimorphic worker caste system with minor workers and major soldiers bearing disproportionately enlarged heads. The species belongs to the Myrmicinae subfamily and is part of the Attini tribe, though it is not a fungus-growing ant like the true attines.
Pheidole subarmata
Pheidole subarmata is a species of big-headed ant in the genus Pheidole, first described by Mayr in 1884. The species belongs to one of the most diverse ant genera globally, with over 1,000 described species in the New World alone. As with other Pheidole species, it exhibits a dimorphic worker caste system with minor workers and major workers (soldiers) distinguished by head size. The species has been documented across South America and the Caribbean.
