Fig. 1 Maximum likelihood (ML) tree estimated using RAxML, showing the relationships of Tantilla, focusing on the T. melanocephala species complex. The bootstrap support values are shown on each node. Bootstrap values below 70% are not shown. Terminals in bold correspond to samples sequenced in this study. Photographs by A. Abegg (T. melanocephala and T. aff. melanocephala), T. Castro (T. boipiranga), and W. Azevedo (T. cf. melanocephala)
