A. B. Meyer and Wiglesworth, 1896,
“Tonkean” [? = Togian Islands], East Sulawesi.
Hitherto considered conspecific with A. monachus, but males differ on account of greenish-black vs rich blue head (in both cases darker on crown than on head sides) (3); dull green vs blue-green tail (2); slightly paler, more uniformly rufous-chestnut underparts (1); slightly larger size (tail showing largest difference; but n=7 combining the sexes; effect size 2.02; score 2); females have back and wings darker and browner (ns[at least 1]). These two species are occasionally placed in genus Dacelalcyon. Monotypic.
E, SE & S Sulawesi, including Butung I (where recently recorded#R).
