(syn. Ceyx Ϯ Northern Indigo-banded Kingfisher C. cyanopectus) Genus Ceyx de Lacépède, 1799, kingfisher; genus Alcyone Swainson, 1837, kingfisher; "The next group has the upper mandible dark, the lower light, with the upper coloration as in the preceding, but reddish underneath, with a sexual blue breast band. The bill is long and of medium width. This species has been the cause of much discussion, first as to its location in Ceyx or Alcyone, and then as to the sexual differences in coloration. It recalls very forcibly in detail the true Alcedo, and may be a direct three-toed derivative of that genus. It requires, however, a new name, and I propose Ceycalcyon, gen. nov. and name Ceyx cyanopectus Lafresnaye as type. C. steerii Sharpe may be a subspecies." (Mathews 1918).
