Subspecies
Taxonomic status uncertain. Sometimes regarded as subspecies of Crested Serpent-Eagle (Spilornis cheela), but apparently does not intergrade with sympatric subspecies pallidus of Crested Serpent-Eagle (Spilornis cheela). Also altitudinally segregated and vocalizations quite different.

Currently considered to form superspecies with Crested Serpent-Eagle (Spilornis cheela), Great Nicobar Serpent-Eagle (Spilornis klossi), Sulawesi Serpent-Eagle (Spilornis rufipectus) and Philippine Serpent-Eagle (Spilornis holospilus).

No subspecies.
