Figure 4.

Distribution of Entomoplasmatales and Bartonellaceae bacteria within and across the sampled subpopulations of Sericomyrmex amabilis hosts and their Megalomyrmex symmetochus guest ants. (A) The four sampling sites in the Panama Canal Zone: Pipeline Road (blue filled square), Barro Colorado Nature Monument (blue open square), Gamboa (blue filled circle), Plantation Road (blue open circle). (B) Maximum‐likelihood phylogeny based on 384 bp of Sericomyrmex mtCOI sequence with Sericomyrmex cf. diego/zacapanus (the closest sympatric relative) as outgroup. Values above the nodes represent support after 1000 bootstrap replicates. Blue symbols behind sample numbers refer to the different sampling locations (panel A; open space means that exact location was unknown). +/− indicates presence/absence of Entomoplasmatales (green) and Bartonellaceae (red) in the ants and fungus gardens.
