). Sequences from individuals taken from the same locality are identical, so all variation recorded is distributed among populations. Haplotypes from Condor and Barro Vermelho differ by 1.71%, but these two differ by an average of 4.11% relative to that from the mouth of the river, which in turn is nearly identical to haplotypes from the upper Rio Urucu to the east of the Rio Juruá (see map, fig. 98 and tree fig. 99). Considerable structure thus occurs over a relatively short distance for this species within the Rio Juruá basin, and further geographic sampling of this species in western Amazonia would be profitable.
