Hitherto treated as conspecific with G. contra, but differs in its uniform whitish-yellow bill vs two-tone orange/whitish-yellow bill (3); large naked orange face patch vs orange eyering (2); bare reddish vs white feathered lores (2). Differs further from G. c. contra in its browner back (ns[1]); whiter underparts (ns[1]); and shorter tail (effect size −1.63, score 1); from G. c. superciliaris in its lack of white streaks on frontal crown (ns[2]); whiter underparts (ns[1]); and longer wing (effect size 2.45, score 2); and from G. c. floweri in its lack of white streaks on crown (3 [consequently discounting score of 2 for lores]); browner back (ns[1]); and shorter tail (effect size −2.56, score 2). Monotypic.
