^aTree includes the fully resolved topologies in the symbionts from the genus Acanthosoma (topology 2 in Additional file 2), maximizing the host-symbiont congruence.
^bTree includes the fully resolved topologies in the symbionts from the genus Acanthosoma (topology 5 in Additional file 2), minimizing the host-symbiont congruence.
^cReconstruction with the maximum numbers of co-divergence events and the lowest cost values.
