Now Vireo leucophrys dissors J.T. Zimmer, 1941 . See Blake, 1968: 129; Olson, 1981: 363–365; Johnson et al., 1988; Dickinson, 2003: 484; and Brewer, 2010: 429–430.

COMMENTS: Zimmer gave the AMNH number of the holotype in the original description and listed (on p. 19) the 15 specimens he examined. The 14 paratypes are: Cerro Munchique, AMNH 109937, 109939, 109940, two males, one female, 3–7 June 1911, by Richardson ; E. of Palmira, AMNH 109129–109132, three males, one female, 19–30 April 1911, by Chapman and Richardson ; Primavera, AMNH 505089, female, 1904, by Raap; San Antonio, AMNH 108344, 108345, 109134, three females, 5 February–30 March 1911, by Chapman and Richardson ; Salento, AMNH 112614, 112615, two males, 27–29 September 1911, by Allen and Miller ; El Eden, AMNH 112613, female, 21 October 1911, by Allen and Miller .

As noted above under disjunctus, Olson (1981: 363–365), as first revisor, selected dissors as the valid name of the form inhabiting the Western and Central Andes of Colombia, and Johnson et al. (1988), treated leucophrys as a full species.
