Hitherto considered conspecific with G. calvus, but differs in having chin and malar tufts greatly reduced (allow 2), colour whitish not yellowish (1); dull creamy-white (not pale brownish-grey with whitish streaks) chin and throat but with more extensive whitish streaking on belly and flanks (compound score 3); paler underparts (1); bill colour reportedly “pale pinkish-horn” vs “pale burnt sienna” or “pale brown” (ns). However, the voices of the two taxa (which approach each other as closely as Cuanza Norte and Cuanza Sul) appear identical#R. Monotypic.
