Tyrant-flycatchers (Tyrannidae)

Sclater's Tyrannulet (Phyllomyias sclateri) - HBW 9, p. 260

French: Tyranneau de Sclater German: Graubrust-Kleintyrann Spanish: Mosquerito de Sclater

Taxonomy: Phyllomyias sclateri Berlepsch, 1901, Bueyes, Santa Cruz, Bolivia.
Genus as presently constituted may be polyphyletic; objective phylogenetic analysis, using molecular characters as well as anatomical ones, is required in order to define generic limits. Anatomical evidence suggests that P. fasciatus, P. griseocapilla and P. griseiceps may be unrelated to others of genus, some or all of which possibly better placed in resurrected genus Tyranniscus. Present species formerly placed in a genus Xanthomyias along with P. virescens; has been suggested that it may belong in a superspecies formed by latter, P. reiseri .. View all taxonomy...

Taxonomy: Phyllomyias sclateri Berlepsch, 1901, Bueyes, Santa Cruz, Bolivia.

Anatomical evidence suggests that P. fasciatus, P. griseocapilla and P. griseiceps may be unrelated to others of genus, some or all of which possibly better placed in resurrected genus Tyranniscus. Present species formerly placed in a genus Xanthomyias along with P. virescens; has been suggested that it may belong in a superspecies formed by latter, P. reiseri and P. urichi. Proposed taxon T. australis is regarded as a synonym of present species. Two subspecies recognized.
