Maximum-likelihood phylogenetic relationships derived from 112 species of brachyuran crabs, using 13 concatenated amino acid sequences (cox1–cox3, cob, atp6, atp8, nad1, nad5, nad4, nad4-L). Some families have been collapsed for increased clarity (triangles). Black circles on nodes represent an SH-aLRT and bootstrap support of greater than 90/90. Stars (*) indicate areas on the tree with taxonomic conflicts related to previous literature. The symbol α indicates the family Xanthidae; β indicates the family Panopeidae. See Supplementary material 1 for a list of the species used and their accession numbers involved in this analysis.
