Hitherto treated as conspecific with G. semiflava, but is genetically closer to G. chiriquensis#R; differs from semiflava by its darker (more brown-tinged) olive upperparts, most obviously on rump and tail (1); possibly broader olive flanks, confining yellow underparts to narrower strip (ns); slightly longer bill (effect size 1.69, score 1); shorter tail (effect size –2.25, score 2); song sometimes a five-second strophe of clearly articulated, repeated notes, but also an ebullient rattling even-pitched warbling at higher speed, much more protracted (2) and with a unique dry rattle incorporated (3), vs a strophe of clearly articulated, repeated notes, lasting c. 5 seconds, slightly accelerating and commonly descending in pitch#R. Monotypic.
