Sometimes regarded as conspecific with A. fischeri, but the two do not interbreed where naturally sympatric (although, where introduced at L Naivasha and a few other highland sites in Kenya, these two taxa have formed stable hybrids); on occasion lumped also with A. lilianae and A. nigrigenis; perhaps best considered to form a species-group with all three. Monotypic.
N & C Tanzania. No evidence of natural occurrence in Kenya, although ecological barrier unclear, and feral populations exist in Kenya (Mombasa, Nairobi and L Naivasha), as well as in Tanzania (Tanga and Dar es Salaam), some mixed and hybridizing with A. fischeri. Overlaps with A. fischeri in N Tanzania (from S of L Manyara S to Babati).
