FIGURE 9. Maximum likelihood phylogenetic tree of the genus Megalothorax (COI, 16S rDNA, 28S rDNA). In parentheses are single individual - extracts id (reported in Genbank and in previous studies, see Schneider et al. 2018 and 2023). Boxes highlight the species of the incertus-group represented with multiple individuals. Bootstrap score ≤ 60 not reported. A '*' indicates species identification established only from the DNA sequences.
