Pseudoatta

The single species and subspecies of this genus are inquilines. Queens live in the nest of Acromyrmex species, have no workers and are entirely dependent on their hosts for food. The queens produce eggs that are cared for and raised to maturity by the host workers. Details about the biology of Pseudoatta argentina can be found in Bruch (1928) and Gallardo (1929). Pseudoatta argentina platensis remains unstudied and is only known from the type material.

Phylogenetically, the species of this genus are nested within Acromyrmex, the genus their hosts belong to. Eventually Pseudoatta will be synonymised with Acromyrmex.
