FIGURE 1. a) map of northeast Brazil showing the localities used in molecular (colored dots) and morphological analysis (colored dots and black diamonds). Light blue lines are rivers, dashed gray lines are state boundaries, the green patch is the Atlantic Rain Forest and the yellow patch is the semiarid Caatinga. b) and c) reduced median network for southern and northern lineages based on b) 1702 bp concatenated mtDNA and c) 1331 bp concatenated nDNA. Each haplotype is represented by a circle and the area of the circle is proportional to its frequency. Samples from different localities are mentioned in different colors as well as same colors/localities relationship is replicated along this paper, Abaeté (dark blue), Guarajuba (green), Costa do Sauípe (brown), Costa Azul (purple), Reserva do Caju (red), Pirambu (light blue), and Parque Nacional da Serra de Itabaiana (PARNASI; yellow). The length of each branch is proportional to the number of mutational steps on the respective branch ("one" was suppressed). The # indicates that the line has been broken to the convenient arrangement of the each nodes.
