Other Notes

Despite the color pattern difference between this species and T. panamensis, the mtDNA divergence between them is much less (3.3%) than the divergence between T. rubrigenis and T. multifasciatus (11.2%). This shows color pattern is not a reliable indicator of relationship in this clade (Victor, 2010).
