Occurrence of F1 hybrids across genera of Formicidae. Estimates of the ratio $\gamma /\theta$ obtained in Formicidae are represented against the topology of genera in this group (retrieved from Antwiki). Genera counting at least one species with $\gamma /\theta >1$ (i.e., probable F1 hybrid) are highlighted by a star. The number of such species per genera, as well as the total number of species per genera are given for each genus. $\gamma /\theta$ ratios higher than two were truncated to two for readability. Three genera with no candidate F1 hybrids (Cryptopone, Pseudoatta, and Strongylognathus), present in UCE capture data but not in the present topology, were not integrated in this representation or in statistical test for phylogenetic correlation.
