Maximum likelihood phylogeny of the A. brunnea species group based on analysis of the combined genes CO1, 28S and 18S with a total alignment of 2447 bp. All four clades within the A. brunnea species group are monophyletic with strong bootstrap support. Bootstrap support (%) for nodes is displayed and branch lengths are proportional to the amount of inferred change, as indicated by the scale bar (mean number of nucleotide substitutions per site).
