Until recently considered a race of H. cantator (which see). Present species differs from H. subflava and H. rondoni in characters given under those species; from H. cantator in its yellow-tinged vs white throat and breast (2); less heavily streaked chest (1); flanks and belly deeper rufous (1); loudsong differing in pace (2) and pace change (2); plus parapatric distribution (3); from H. peruviana in its white vs black-streaked throat and breast (2); olive-ochreish vs chestnut scapulars and wing fringes (2); ochre vs rufous flanks and equivalently shaded tail (1); loudsong with somewhat different pace (1) and note shape (1); from H. ochrogyna in olive flecking to black parts of crown and back in female (2); pale yellow vs whitish underparts (1); less scaling on breast (1); loudsong with different pace (1) and pace change (2); and from H. striata in its pale yellow vs whitish underparts (2); much lighter streaking on breast (2); paler, duller mantle (1); loudsong with different pace (1) and pace change (2). Birds of N & C Roraima sometimes separated as race perflava, but validity doubtful, and unchecked in recent study due to lack of vocal recordings#R. Monotypic.
