In the past sometimes thought to be conspecific with T. nudigenis (which see, below), but differences considered too great to warrant such treatment. Geographical variation for the most part very slight; some races perhaps better merged. Proposed race umbrinus (from Guatemala) apparently based on fresh nominate specimens. Nine subspecies currently recognized.

Subspecies and Distribution
