Traditionally considered to form a species-group with A. laminirostris and A. cucullata. HBW described races as “poorly differentiated”, but lateralis possesses pale vs dark eyes (3) and pink vs orange on distal upper mandible (2), suggesting considerable distinctiveness, with broad zone of intergradation in Ecuador (1), hence close to species status. Nevertheless, division between races somewhat unclear, individuals with largely nominate characters (dark irides, orange on bill) occurring in E Ecuador S to Papallacta–Baeza, whereas S of Gualeco–Limón road lateralis-type populations (paler irides, strong pink on bill) appear, and specimen from Cañar (SC Ecuador) appears somewhat intermediate#R; note, however, that most of those in N Peru N of Marañón Gap also have dark irides#R, so zone of intergradation perhaps even broader than thought. Two subspecies recognized.
