Tyrant-flycatchers (Tyrannidae)

Euler's Flycatcher (Lathrotriccus euleri) - HBW 9, p. 354

French: Moucherolle d’Euler German: Euler-Schnäppertyrann Spanish: Mosquero de Euler

Taxonomy: Empidochanes Euleri Cabanis, 1868, Cantagalo, Rio de Janeiro, Brazil.
Genus formerly included within Empidonax. If present species is included in Empidonax, name flaviventris becomes preoccupied, and must give way to johnstonei for Grenada birds; those from Trinidad also, independently, named as flavirostris (by same author, in same year!), but that name, preoccupied in both genera, gives way to lawrencei. Five subspecies recognized.

Subspecies and Distribution:

flaviventris (Lawrence, 1887) - Grenada, in S Windward Is (probably extinct).
lawrencei (J. A. Allen, 1889) - Trinidad, W & N Venezuela, locally E Colombia, also casually Surinam and French Guiana.
bolivianus (J. A. Allen, 1889) - S & SE Venezuela, E Ecuador, E Peru, much of Brazil (except N & SE) and NW Bolivia; some possibly migrate to Colombia.
