Vireo gilvus disjunctus J.T. Zimmer

Vireo gilvus disjunctus J.T. Zimmer, 1941: 18 ( Santa Elena, Antioquia, Colombia; altitude 9000 feet).

Now Vireo leucophrys dissors J.T. Zimmer, 1941 . See Blake, 1968: 128; Olson, 1981: 363–365; Johnson et al., 1988; Dickinson, 2003: 484; and Brewer, 2010: 429–430.

HOLOTYPE: AMNH 134056 , adult male, collected at Santa Elena, 9000 ft, 06.13N, 69.55W ( Paynter, 1997), Antioquia, Colombia, on 18 November 1914, by Leo Miller (no. 10115) and Howarth Boyle.

COMMENTS: Zimmer gave the AMNH number of the holotype in the original description and listed (on p. 19) the six specimens he examined. The five paratypes are: Santa Elena, AMNH 134057 , 134059 , 134061–134063 , one male and four females, 18 November–2 December 1914, collected by Miller and Boyle ; ‘‘ Bogota ,’’ AMNH 505093 , sex?. AMNH 134058 and 134060 were exchanged to other museums before Zimmer named this form and were not part of his type series .

Olson (1981: 363–365) found that dissors Zimmer (see below) and disjunctus Zimmer were inseparable and, as first revisor, chose dissors to ‘‘represent the subspecies of Vireo gilvus inhabiting the entire extent of the Western and Central Andes of Colombia.’’ Studies by Johnson et al. (1988: 442) supported earlier treatment of leucophrys as a full species, distinct from Vireo gilvus . This has been followed by more recent ornithologists.
