Subspecies
Apparently a rather isolated species in the genus, differing from other small Batrachostomus in lacking sexual dichromatism and in pattern of underpart feathers. Although recognition of Bornean population as a separate subspecies (parvulus) is sometimes suggested, geographical variation of species is slight at most.
