The molecular diversity in the Mantiqueira and Serra do Mar clades is relatively reduced, as haplotypes within these regions average 0.45% and 0.64% pairwise genetic distance, respectively. The Southern clade, on the other hand, exhibits larger polymorphism, with haplotypes averaging 0.91% of pairwise genetic distance. The larger intraclade genetic distance in the Southern group is due to comparisons between haplotypes from the northernmost (states of São Paulo and Paraná) and southernmost localities (states of Santa Catarina and Rio Grande do Sul), which diverge by 1.47% pairwise genetic distance in average. However, the positive and significant correlations between genetic and geographic distances of populations assessed by a Mantel test (

, this last option does not seem practical, since the recognition of subspecies would be fully dependent on molecular data in the absence of diagnostic morphological characters between the Serra do Mar and Mantiqueira populations.

reported a high frequency of specimens from Boracéia and Casa Grande, in São Paulo state, with white tipped tails. This condition was not found in other samples from Serra do Mar examined by us, such as those from Teresópolis or Parati, in the Rio de Janeiro state, and may rather be a locally polymorphic character. The Serra do Mar clade is also polymorphic for tail color pattern, with a higher frequency (57%) of weakly bicolored tails in samples from Alto da Serra, Boracéia and Casa Grande, while other samples of this clade exhibit higher frequencies (>60%) of strongly bicolored tails. Given the current uncertainty in the morphological discrimination among the three clades of
