Subspecies
Birds on Kasiruta presumed to belong to nominate subspecies, but confirmation needed. Original spellings of genus and species names were "Semeioptera wallacei", but these spellings have both been formally rejected by ICZN and the current spellings formally protected.
The following 2 subspecies are recognised:
halmaherae Salvadori, 1881 - Halmahera, in northern Moluccas.
wallacii Gould, 1859 - Kasiruta and Bacan, off south-western Halmahera.
