Quoy and Gaimard, 1830,
island of Vanikoro, in Santa Cruz Islands.
Has been thought to be closely related to A. inquietus, A. pelewensis, A. bartschi and A. salangana, and all were formerly considered conspecific; A. mearnsi, too, was previously included in this group. Both A. infuscatus and A. hirundinaceus have been treated as races of present species. Races palawanensis and amelis sometimes considered two (or one#R) distinct species; former has been treated as conspecific with A. maximus or A. whiteheadi, and latter with A. fuciphagus; molecular findings in one study#R that palawanensis is sister to A. mearnsi and that race lugubris is considerably differentiated are suggestive, but amelis and forms from Sulawesi not sampled, so amelis and palawanensis for the present retained here. Races aenigma and heinrichi sometimes considered to belong to A. salangana. Population on Yamdena, in Tanimbar Is, not yet subspecifically assigned and may belong to an undescribed race. Australian birds formerly treated alone as race yorki, with name granti applied to New Guinea birds; the only two Australian records, however, refer to vagrants identical to the New Guinea form, and it is clear that only a single race is involved; this race often listed as granti, but name yorki has priority by 21 years. Proposed race tsubame of A. whiteheadi now considered a synonym of race palawanensis. Fourteen subspecies currently recognized.
Also (subspecies unknown) Yamdena, in Tanimbar Is.
