Sometimes considered conspecific with C. albobrunneus and may hybridize with it in S Colombia; proposed race aenigmaticus (from Nariño, in SW Colombia) is possibly a hybrid between them and a DNA sample from this population proved to be sister to C. albobrunneus#R. Close relationship to C. megalopterus also postulated, although their ranges overlap with no evidence of interbreeding, and recent molecular study recovered evidence that present species is paraphyletic in relation to C. megalopterus, thus taxonomy of present species might require revision#R. Proposed race panamensis (described from WC Panama) very similar to, and intergrading with, costaricensis, considered better merged with latter. Seven subspecies recognized.
