Subspecies
Often treated as conspecific with Ptilorrhoa geislerorum, but the two show some altitudinal separation in area of co-existence in northern New Guinea (near Madang). They also differ in behaviour, vocalizations and female plumage.
The following 4 subspecies are recognised:
caerulescens (Temminck, 1835) - West Papuan Is (Salawati, Misool) and north-western New Guinea (Vogelkop east to R Wanggar and Etna Bay).
neumanni (Mayr & Meyer de Schauensee, 1939) - Northern New Guinea from R Mamberamo east to Astrolabe Bay.
nigricrissus (Salvadori, 1876) - Southern New Guinea from R Wanggar and Etna Bay east to Milne Bay.
geislerorum (Meyer, AB, 1892) - Eastern New Guinea. Considered by some authors to be a distinct species, Dimorphic Jewel-babbler (Ptilorrhoa geislerorum).
