Subspecies
No subspecies.
Formerly considered conspecific with Tepui Whitestart (Myioborus castaneocapilla), but the two differ in their songs and are widely separated geographically. Treatment as separate species supported by recent phylogenetic study, which suggested that close plumage similarities between the two may be due to retention of ancestral traits, rather than to genetic similarity.
