Differences in display and behaviour do not suggest particularly close relationship with L. nuna; may be more closely related to Sappho sparganurus. Proposed race aequatorialis (W Ecuador) doubtfully distinct from nominate, only difference documented being in tail length, which is quite a variable character within nominate. Proposed race eucharis (from C Peru, formerly thought to have come from Colombia) was provisionally placed in present species before transfer to L. nuna, but now thought to be a hybrid between the two#R. Described form L. ortoni is probably a hybrid between present species and Ramphomicron microrhynchum, and Zodalia glyceria a hybrid between present species and Chalcostigma herrani#R. Three subspecies recognized.
