Taxonomy and systematics
The Spillmann's tapaculo was previously considered a subspecies of brown-rumped tapaculo (Scytalopus latebircola) but was elevated to species rank due to differences in their vocalizations. It and chusquea tapaculo (S. parkeri) form a superspecies. The population in Colombia's eastern Andes might be different enoung to be a subspecies.
