Related Species

The Gray-bellied Flowerpiercer is a member of the family Thraupidae, the tanagers, a member of the subfamily Diglossinae, and a member of the genus Diglossa. This genus contains 18 species. A more recent study (Burns et al. 2014) identified Catamenia as the sister to Diglossa with strong support. D. brunneiventris was previously a subspecies of D. carbonaria (Vuilleumier 1969, Graves 1982). Studies using cytochrome b and ND2, along with additional nuclear sequences, found a rapid radiation of the four species in the former carbonaria superspecies (Mauck and Burns 2009, Burns et al. 2014). The amount of sequence divergence among the species within the carbonaria superspecies – D. carbonaria, D. brunneiventris, D. gloriosa and D. humeralis – is less than that found in other flowerpiercer subspecies. However, the plumage patterns found within the carbonaria superspecies are the most variable of all flowerpiercer subspecies (Mauck and Burns 2009). Phylogenetic analyses using BEAST indicate that the earliest node of the carbonaria superspecies group dates to 0.475 Mya (Mauck and Burns 2009). The Bayesian and likelihood trees of Mauck and Burns (2009) differ in their placement of species within the carbonaria superspecies complex. In the Bayesian tree, D. carbonaria is the sister taxon to D. humeralis, whereas likelihood analyses place D. carbonaria as the sister taxon to a clade containing D. gloriosa and D. humeralis (Mauck and Burns 2009). However, there was no strong support for relationships within the carbonaria superspecies.
