Classification unstable; commonly treated as conspecific with L. calolaemus and L. castaneoventris, but, while females of all taxa are very similar, combination of highly distinctive male plumages and parapatric distributions, along with observations that where white-throated and purple-throated forms occur on the same slopes they tend to segregate altitudinally (white-throated higher), suggests species status more appropriate; hybridization is very limited, and many previous reports of hybrids may refer to young birds. Thus, cinereicauda achieves species status, distinct from castaneoventris by its blue vs green forecrown (3), grey vs dark blue tail (3) and parapatry (3), and from calolaemus by its white vs purple throat (3), grey vs dark blue tail (3) and parapatry (3). Monotypic.
