Subspecies
No subspecies.
Affinities of genus uncertain. Long hypothesized as being closest to Conopias, largely on basis of similar hole-nesting tendencies. Genus probably monophyletic, although this only weakly supported by recent analyses of molecular-sequence data (likely due to inappropriate markers for the apparently long branches and deep level of divergence within genus). Results of separate analyses of plumage/syringeal morphology and molecular data were not completely congruent, but do suggest some strong tentative conclusions. Previously considered conspecific with Golden-crowned Flycatcher (Myiodynastes chrysocephalus). Recovered as sister-taxa under certain coding schemes of morphological characters, and as a clade with very strong bootstrap support in all analyses of molecular data.
