Biology
P. sublaevis reproduces via gamergates, but only a single worker in the colony is mated and performs all reproduction in the colony (Ito & Higashi, 1991; Peeters et al., 1991). Workers in a colony are organized in a strict linear hierarchy determined by age and by ritualized dominance displays (Higashi et al., 1994).

Colonies are exceptionally small (9±2.5 workers, sample of 12 colonies) (Peeters et al., 1991).

Castes
Winged queens are absent in this species
