Thought to be close to A. acuta, with which (and A. eatoni) is sometimes partitioned off in genus Dafila. One genetic study suggested that present species forms a monophyletic group with A. acuta and A. bahamensis#R. Subspecies niceforoi, described in 1946, had been considered to be extinct by 1956, but was reportedly rediscovered in Jan 2003#R; however, claim is not convincingly documented, has been questioned#R and comes from a region (Cauca) over which disagreement apparently exists as to the subspecies that occurs there. Race spinicauda sometimes considered a full species, but apart from being significantly larger is not particularly distinctive. Two extant subspecies recognized.
