Collocalia whiteheadi papuensis
Idenburg River, western New Guinea.
Unique among Apodidae in lacking fourth toe. One phylogenetic study indicated that present species was basal to other Aerodramus and even that it and Hydrochous gigas are sister taxa, a relationship that would indicate paraphyly of genus Aerodramus#R. Monotypic.
New Guinea: specimens collected from Idenburg R, Snow Mts and Jayapura. Probable sight records from more extensive area of N New Guinea and from around Port Moresby, in SE; first specimen for Papua New Guinea taken from N slopes of Hindenburg Range, in Western Province, Apr 1993.
