Collection places of individuals of T. obscurus and geographic distribution of the cytotypes: Santarém (white circle); Belém (grey triangle); Benevides (white triangle); Santa Bárbara (black triangle); Áfua (black square); Moju (white square); Acará (grey circle); Bragança (black circle); Rurópolis (grey square). The letters adjacent to the karyotypes represent their cytotypes. Note the greater diversity of karyotypes in Santarém (putative distribution center for the species). The arrows next Santarém indicate the dispersion of these cytotypes to marginal regions. This map is the work of Bruno Rafael Ribeiro de Almeida and used with permission
