Up to HBW, considered conspecific with A. somptuosus, and treatment there provisional, pending vocal analysis; this provided here (although difference already indicated#R), but in fact present species scores sufficiently on morphological characters alone, differing in its black of forecrown extending to upper rear crown (2); rump shining powder-blue vs black or dark green (3); lack of blue on outer edges of secondaries (2); virtual lack of blue on outer rectrices, so tail appears almost all black (ns[2]); plus song comprising 7–11 low-pitched melodious whistles, starting at low volume and gradually getting louder, vs only high-pitched vocalizations with little structure (scores for number of notes and minimum frequency 3+3=6)#R. Monotypic.

Distribution:

E slope of Andes in Peru (from E Cuzco#R) S to S Bolivia (Chuquisaca).
