Usually considered conspecific with L. brasiliana and hitherto with L. juliae; for differences, see those species. Nominate race intergrades and hybridizes with rather distinctive henkei (hybrids described as race theresae) and race trochilus does so with L. juliae (hybrids described as race davaoensis); an apparently stable hybrid population exists on Sibuyan (NC Philippines). Other proposed races in Philippines are manueli (from Karlagan, in Polillo Is), synonymized with nominate; minima (Mati Municipality, in Davao Province of Mindanao), synonymized with trochilus; and whiteheadi (N Luzon), subsumed into henkei. Described form marinduquensis is based on misidentification of female of Aethopyga magnifica. Three subspecies recognized.
