After confirming the placement of Saltator rufiventris outside Saltator (Fig. 1; Klicka et al., 2007), we omitted this taxon from all further analyses. ...
From a purely taxonomic point of view, the genus Saltator as currently configured remains paraphyletic. Despite its morphological dissimilarity, Saltatricula multicolor is clearly a member of this genus. Saltator coerulescens and S. maximus both harbour deeply divergent clades occurring on either side of the Isthmus of Panama. Minimally, these clades warrant recognition as phylogenetic species. Recent studies in Neotropical birds have revealed that traditional species-level taxa often conceal cryptic, genetically divergent lineages that are later found to represent new species (e.g. Milá et al., 2012). We recovered several such lineages within Saltator (S. maximus, S. grossus, S. aurantiirostris, S. coerulescens and S. striatipectus; see Fig. 2), although additional work on these taxa is required to better inform any additional taxonomic revisions. If these splits represent hidden lineages and given that most of these 'cryptic splits' have occurred during the Pleistocene, a more prominent role of Quaternary diversification in this group should be acknowledged.
