(syn. Corythornis Ϯ Madagascar Pygmy Kingfisher C. madagascariensis) Genus Ceyx de Lacépède, 1799, kingfisher; Gr. -οιδης -oidēs resembling; "Another unicum which must be specialised by a generic name is Linné's Alcedo madagascariensis, placed under Ispidina by Sharpe. This has the short, broad red bill of the latter genus, but is essentially distinct in that it is wholly reddish above and white below, the sides of the body red. There is no blue in the colours at all, nor is the head barred. It is obvious that we have here a different evolutionary product, though the source is at present unknown to me. For this group I propose Ceycoides, gen. nov., the type and only species being Ceycoides madagascariensis (Linné.)  In coloration this group recalls the true Ceyx, but among the four-toed birds that genus is represented by Ceycopsis, which suggests once more convergence in colour-schemes." (Mathews 1918).
