If species included in Empidonax, name flaviventris becomes preoccupied, and must give way to johnstonei for Grenada birds; those from Trinidad also, independently, named flaviventris (by same author, in same year, but in different genus), but this name, preoccupied in both Empidonax and Lathrotriccus, gives way to lawrencei. Five subspecies recognized.
