Tyrant-flycatchers (Tyrannidae)

Yellow-throated Flycatcher (Conopias parvus) - HBW 9, p. 411

French: Tyran de Pelzeln German: Weißring-Maskentyrann Spanish: Bienteveo Guayanés
Other common names: Yellow-crowned Flycatcher

Taxonomy: Pitangus parvus Pelzeln, 1868, Marabitanas, Rio Negro, Brazil.
Has been hypothesized, on basis of hole-nesting behaviour, that genus may be most closely related to Myiodynastes, with this clade basal to a “Tyrannus group” that also includes Megarynchus, Tyrannopsis, Empidonomus and Griseotyrannus; molecular-sequence data, however, do not support an affinity between these two genera, but strongly suggest that present genus is part of that group to the exclusion of Myiodynastes. This species was formerly placed with C. albovittatus in a separate genus, Coryphotriccus, on grounds mainly of slightly larger bill and presence of a coronal patch, but syringeal morphology is similar to that of present genus. The two are sometimes considered conspecific, but differ in plumage and, especially, voice; furthermore, molecular-sequence data indicate substantial divergence between them, but also that they are closely related and represent a sister-group to a clade consisting of C. cinchoneti and C. trivirgatus. Monotypic.

Distribution: S & E Venezuela (W Amazonas E locally to E Bolívar), extreme E Colombia (E Vaupés, Guainía), very locally NE Ecuador (E Sucumbíos, extreme SE Pastaza), extreme NE Peru (N Loreto); also the Guianas, and Brazil primarily N of Amazon and R Solimões (locally from N Roraima and upper R Negro S to lower R Negro near Manaus, E to Amapá; also recorded S of Tefé near R Urucu, in W Amazonas).
