, 1932,

Tanke Salokko, 2000 m, Mengkoka Mountains, south-eastern Sulawesi

.

Hitherto considered conspecific with A. princeps, but (from evidence of only known two specimens) differs on account of black vs dark blue forecrown and “face” (malar area to ear-coverts) and dull blue-green vs dark blue mid-crown to hindcrown (3); lack of buff barring on mantle, back and scapulars (2); much stronger buff on underparts (at least in female) (2). These two species occasionally placed in genus Monachalcyon. Monotypic.

Distribution:

SE Sulawesi.
