Subspecies
Formerly considered conspecific with Philippine Bush-hen (Amaurornis olivacea), but sufficiently distinctive in plumage to merit separation. Probably best considered as forming superspecies.
The following 4 subspecies are recognised:
moluccana (Wallace, 1865) - Sangihe Is, Moluccas, Misool I and western and northern New Guinea.
nigrifrons (Hartert, 1926) - Bismarck Archipelago and Solomon Is.
ultima Mayr, 1949 - Eastern Solomon Islands.
ruficrissa (Gould, 1869) - Southern and eastern New Guinea, and north-eastern and eastern Australia.
