Myioborus chrysops ( Salvin, 1878 )

Cuervo, Andrés M. & Céspedes Arias, Laura N., 2023, The type of Setophaga ruficoronata (Kaup 1851) is a hybrid: implications for the taxonomy of Myioborus warblers (Passeriformes: Parulidae), Zootaxa 5383 (4), pp. 476-490 : 484-486

Myioborus chrysops ( Salvin, 1878) , subspecies elevated to species rank

Proposed English name: Colombian Redstart. Protonym: Setophaga chrysops . Type: NHMUK 1885.3.8.804 ( Fig. 7 ). Type locality: Santa Elena, Antioquia, Colombia. Range of the species: Western and Central Andes, and the southern end of the Eastern Andes of Colombia (Páramo de Miraflores between Huila and Caquetá) south to the Colombian Massif in southern Cauca. Monotypic. Myioborus chrysops is the species hybridizing with M. bairdi in extreme southern Colombia and northern Ecuador.

A specimen (NML-VZ D1932, Fig. 6C ) with a red label and marked as “ type ” for flaveola (not of Lafresnaye 1844, but one cited by Kaup, 1851) is not a proper name-bearing type. It corresponds to an adult M. chrysops that was identified by Kaup (1851) as flaveola , and collected by De Lattre at Puracé (Cauca, Colombia).

FIGURE 6. Type specimens of names synonymized with Myioborus ornatus sensu stricto, and M. chrysops. Types of flaveola (A, MCZ 76106) and leucophomma (B, NML-VZ D2009), which correspond to juvenile and immature individuals of M.ornatus, respectively. Kaup (1851) identified as flaveola a specimen that corresponds to M. chrysops (C, NML-VZ D1932), but this is not a true type specimen (see text).

This taxon is currently treated as M. ornatus chrysops, and is the “pure” northern form hybridizing with bairdi in southern Colombia (see text).
