Trogon melanocephala

Original description clearly treats species name as adjectival; hence this becomes masculine to agree with genus name. Present species sometimes considered conspecific with T. citreolus; genetic data indicate that these two form a sister-group to T. viridis and T. bairdii#R. Populations of W Costa Rica described as race illaetabilis on basis of paler belly, but this character apparently not constant. Monotypic.

Distribution:

Atlantic slope of SE Mexico (including islands off Quintana Roo), N Guatemala, Belize, N Honduras and Nicaragua; also Pacific slope from El Salvador to N Costa Rica.
