‘ Osteocephalus mimeticus group’

The majority rule consensus delimited two OTUs within the ‘ Osteocephalus mimeticus group’ ( Fig. 1a ). One of them unambiguously corresponds to Osteocephalus mimeticus Melin, 1941 ( Fig. 3b in the Appendix) containing a sequence from its type locality. The sequences of the other OTU ( O. aff. mimeticus ) are from the Cusco department, in Peru, and form a highly divergent sister group to O. mimeticus sensu stricto ( Fig. 1a ); they substitute each other latitudinally (Electronic Supplement 3).

Fig. 1 Panel a, time-calibrated phylogeny of Osteocephalus, Tepuihyla and Dryaderces in Amazonia, resulting from a mitogenomic analysis in BEAST and displaying the mean and 95% CI (blue bars) of divergences. Nodes are numbered in red (age details are in Electronic Supplement 1), and support values are depicted for Bayesian (following node symbol colours) and maximum likelihood analyses (following numbers below the nodes). Topological discrepancies between analyses for four low-supported nodes (21, 25, 34 and 43)
