Subspecies
Helmeted Friarbird (Philemon buceroides) and New Guinea Friarbird (Philemon novaeguineae) (Sibley and Monroe 1990, 1993), cross-regional species, are treated as seperate species by BirdLife International, whereas Christidis and Boles (1994) include novaeguineae as a subspecies of buceroides.
In northern Australia, subspecies gordoni and ammitophilus occupy different habitats and appear to be allopatric; possibly represent two separate species.
Other proposed subspecies are sumbanus (from Sumba, in Lesser Sundas) and plesseni (Lomblen, in Lesser Sundas), both merged with neglectus; pallidiceps (Wetar, in Lesser Sundas), synonymized with nominate; brevipennis (Utakwa R, in southern New Guinea), fretensis (Hall Sound, in south-eastern New Guinea) and trivialis (Collingwood Bay, on northern coast of south-eastern New Guinea), all subsumed in novaeguineae; and, in Australia, confusus (from Cairns, in northern Queensland), treated as synonym of yorki.
The following 10 subspecies are recognised:
neglectus (Büttikofer, 1891) - Lombok, Sumbawa, Moyo, Sangeang, Komodo, Rinca, Flores, Besar, Adonara, Lomblen, Pantar, Alor and Sumba, in Lesser Sundas.
buceroides (Swainson, 1838) - Sawu, Roti, Semau, Timor, Atauro and Wetar, in eastern Lesser Sundas.
gordoni Mathews, 1912 - Northern Northern Territory (Tiwi Is and coastal Arnhem Land), in northern Australia.
ammitophilus Schodde, Mason, IJ & McKean, 1979 - Subcoastal sandstone plateaux of Arnhem Land (south to Katherine Gorge and Mataranka), in northern Territory.
novaeguineae (S. Müller, 1843) - New Guinea. Considered by some authors to be a distinct species, New Guinea Friarbird (Philemon novaeguineae).
jobiensis (A. B. Meyer, 1874) - Yapen I (in Geelvink Bay) and northern New Guinea from Mamberamo R east to southern coastal Huon Gulf (around Salamaua). Considered by some authors to be a subspecies of New Guinea Friarbird (Philemon novaeguineae).
aruensis (A. B. Meyer, 1884) - Aru Is. Considered by some authors to be a subspecies of New Guinea Friarbird (Philemon novaeguineae).
subtuberosus E. J. O. Hartert, 1896 - Trobriand Is (Kaileuna, Kiriwina and Kitava) and D'Entrecasteaux Archipelago (Goodenough, Fergusson and Normanby), off south-eastern New Guinea. Considered by some authors to be a subspecies of New Guinea Friarbird (Philemon novaeguineae).
tagulanus Rothschild and E. J. O. Hartert, 1918 -
Tagula I, in Louisiade Archipelago (off south-eastern New Guinea). Considered by some authors to be a subspecies of New Guinea Friarbird (Philemon novaeguineae).
yorki Mathews, 1912 - Islands in central-western and southern Torres Strait, and coastal north-eastern Queensland (south to Weipa, on western Cape York Peninsula, and, in east, to Broad Sound, including some offshore islands), in north-eastern Australia. Considered by some authors to be a distinct species, Hornbill Friarbird (Philemon yorki).
