Maximum likelihood (ML) phylogeny based on concatenated mtDNA and nDNA datasets for Quadrulini. Nodes are collapsed into species-level clades. Asterisks above and below branches represent ≥99% ultrafast bootstrap and 0.99 posterior probability support, respectively. Number in parentheses after taxon name indicates sample size. The fully resolved phylogeny with ultrafast bootstraps and posterior probability support values are available as Supplementary Figs S1 and S2, respectively.
