Accession numbers for the sequences used to infer the ant phylogeny

Accession numbers for the sequences used to infer the ant phylogeny. In species where molecular data were not available (indicated with *), we used sequences from closely related congeners. COI barcodes for the species listed as ‘Processing’ were provided by D. Donoso and obtained in collaboration with the Biodiversity Institute of Ontario, using sequencing techniques and analytical tools in the Barcode of Life Database (BOLD; www.boldsystems.org/). New sequences for the study, as well as sequences for C. sumichrasti and P. villosa, are publicly available in the BOLD database, in the project ‘AOFBA’ named Ants of BCI_2_Project Atta. Molecular data included three genes: Cy-tochrome Oxidase I (COI; mitochondrial), wingless (nuclear), and long wavelength rho-dopsin (LWRh; nuclear).
