Mount Data, Luzon, Philippines.
In the past considered conspecific with A. orientalis, but apparently not closely related. Formerly linked with A. brevirostris, but differs in nest type and rump pattern. Has also been considered conspecific with A. papuensis, but does not lack fourth toe. Two forms previously listed as races of present species are now synonymized with other congeneric taxa: tsubame with A. vanikorensis palawanensis; and apoensis with A. mearnsi. Many old records attributed to this species refer in fact to A. vanikorensis amelis. Two subspecies recognized.
Single record from Negros (Mt Kanla-on) in 1998#R.
