Hitherto treated as conspecific with A. lunulatus, but differs in its orange-red vs scarlet lower underparts (1); pale blue vs undifferentiated fringes to greater wing-coverts and remiges (2); shorter blue median coverts, making a smaller wing patch (2); grey-black vs jet-black upperparts (ns[1]); green tinge to powder blue rump (ns[1]); less black in tarsal feathering (ns[1]); shorter wings (effect size vs next smallest A. l. ignicrissa –1.24, score 1, but with bill larger than in ignicrissa, effect size 0.69, score 1; effect size for wing vs A. l. lunulatus –2.89 and vs A. l. erythrotus –3.78, both score 2); much higher-pitched song (most energy in range 5–10 kHz vs <6 kHz; based on maximum frequency score 3) and lack of nasal or twangy notes (score 1); narrow zone of hybridization in Junín, Peru, resulting in mixed songs there (2)#R. Monotypic.
