Pogonomyrmecini
Pogonomyrmecini is a tribe of myrmicine ants established in 2015, containing three extant genera: Pogonomyrmex, Hylomyrma, and Patagonomyrmex. The tribe was erected following phylogenetic revision of the subfamily Myrmicinae. Members include the well-known harvester ants (Pogonomyrmex), which are conspicuous seed-collecting ants in arid regions of the Americas. The tribe represents a relatively recent taxonomic reorganization based on molecular and morphological evidence.

Pogonomyrmex colei
Pogonomyrmex colei is a workerless inquiline ant species in the subfamily Myrmicinae. It is a permanent social parasite that lacks a worker caste entirely, with only reproductive queens and males present. The species is native to the southwestern United States, where it parasitizes nests of the harvester ant Pogonomyrmex rugosus. Its genome has been sequenced to study the genetic mechanisms underlying the evolutionary loss of the worker caste.

Rogeria
Djirries
Rogeria is a genus of small ants in the subfamily Myrmicinae, distributed primarily in the Neotropical region. The genus contains approximately 40 described species, most of which inhabit leaf litter and soil in tropical forests. Workers are minute to small in size and often exhibit reduced eyes or eyelessness. The genus is distinguished by specialized mandibular structures and reduced pilosity compared to related myrmicine ants.

Solenopsis molesta
thief ant, grease ant
Solenopsis molesta is a small myrmicine ant known for its habit of nesting near other ant colonies and stealing their food and brood, earning it the common name 'thief ant.' Workers are tiny (0.5–3 mm), yellow to pale brown, with reduced eyes and a two-segmented petiole. The species is native to the United States and northern Mexico, where it occupies diverse habitats from soil and rotting logs to human dwellings. Colonies range from a few hundred to a few thousand workers and may be polygynous. Nuptial flights occur from late July through early fall. The species is attracted to grease and protein sources rather than sweets, making it a distinctive household pest that is difficult to control due to its small size and inaccessible nesting sites.

Solenopsis pergandei
Pergande's Thief Ant
Solenopsis pergandei is a small thief ant species in the genus Solenopsis, described by Forel in 1901.
