E. Bartlett, 1880,
Commonly treated as conspecific with A. barbatus, but “differs in appearance from the other races of A. barbatus by at least as much as do the other members of the superspecies [A. bradfieldi, A. sladeniae, A. berliozi]”#R, being (compared with barbatus) “smaller…, with blacker head and body, and smaller pale throat-patch with distinct dark streaks”#R; scoring not attempted but “strong molecular differentiation… against… A. barbatus”#R adds evidence to support split. Two subspecies recognized.
