Isthmus of Panama.
Formerly placed with C. parvus in a separate genus, Coryphotriccus, on grounds mainly of slightly larger bill and presence of coronal patch, but syringeal morphology is similar to that of present genus. These two species are sometimes considered conspecific, but differ in plumage and, especially, voice; molecular data indicate substantial divergence between them, but also that they are closely related and represent a sister-group to a clade consisting of C. trivirgatus and C. cinchoneti. Validity of race distinctus questionable. Two subspecies currently recognized.
