(syn. Ceyx Ϯ Moluccan Dwarf Kingfisher C. lepidus) Gr. κυανος kuanos  dark-blue; genus Ceyx de Lacépède, 1799, kingfisher; "The Alcedinine species of Ceyx are more intricate, and four groups can be easily distinguished, one with red bills, one with particolored bills, and two with black bills. The red-billed group has the head barred with blue, the Alcedine dorsal greenish-blue tract, the white throat, and the under-parts otherwise yellowish. In this group we see colour changes, though the color pattern remains exact above and the coloration practically the same below. It is probable that two groups are again here confused, but I cannot separate them at the present time. I propose to name this group Cyanoceyx, gen. nov., and select Ceyx lepida Temminck as type. I refer to the present group wallacei Sharpe, cajeli Wallace, goodfellowi Ogilvie-Grant, bournsi Steere, malamaii Steere, collectoris Rothschild and dispar Rothschild and Hartert." (Mathews 1918).
