Divergence of ant social parasites

Caption

Divergence estimates for Acromyrmex host and inquiline parasite species. ime-calibrated phylogeny of the fungus-growing ants for which genomes have been sequenced, including the three inquiline social parasite species and their two host species. The two origins of social parasitism in Acromyrmex (orange dots and boxes) occurred ca. 0.96 Ma ago for A. insinuator (1) and ca. 2.50 Ma ago when the ancestor of A. heyeri diverged from the stem group representative of Pseudoatta argentina (2) and A. charruanus (3).
