Tyrant-flycatchers (Tyrannidae)

Rough-legged Tyrannulet (Phyllomyias burmeisteri) - HBW 9, p. 259

French: Tyranneau pattu German: Burmeisterkleintyrann Spanish: Mosquerito de Burmeister
Other common names: White-fronted Tyrannulet (leucogonys); Zeledon’s Tyrannulet (zeledoni)

Taxonomy: P[hyllomyias] Burmeisteri Cabanis and Heine, 1859, Rio de Janeiro, Brazil.
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 was for long treated in its own genus, Acrochordopus, because of distinctively serrated tarsus, but tarsal scutellation now known to be unreliable as a generic cha..

Taxonomy: P[hyllomyias] Burmeisteri Cabanis and Heine, 1859, Rio de Janeiro, Brazil.
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 was for long treated in its own genus, Acrochordopus, because of distinctively serrated tarsus, but tarsal scutellation now known to be unreliable as a generic character in the family. Nominate race and zeledoni sometimes considered to represent two distinct species, with the other four (“leucogonys group”) forming a third species, but biological information about all populations remains scarce, and vocal and genetic relationships not yet studied; investigation needed especially in area of possible contact between leucogonys and nominate in S Peru and N Bolivia. Six subspecies recognized.

Subspecies and Distribution:

  • zeledoni (Lawrence, 1869) - Costa Rica and W Panama.
  • wetmorei (Aveledo & Pons, 1953) - Sierra de Perijá, in W Venezuela.
  • viridiceps (J. T. Zimmer & Phelps, Sr, 1944) - mountains of N Venezuela.
