Hitherto considered conspecific with G. bonapartei owing to zone of intergradation in C DRCongo (where populations formerly separated as race intermedius), but this not an obstacle here to its separation, based on larger size (effect size for wing 3.32) (2); proportionately rather longer nasal tufts (but these not measured; ns[1]); pale iris (3); whiter, narrower streaks on forecrown (1); blacker tail (1); broad hybrid zone (1). Monotypic.
