(syn. Todiramphus Ϯ Rufous-lored Kingfisher T. winchelli) Genus Dilazula Mathews 1918, kingfisher; L. suffix -ena  relating to (cf. Gr. δι- di-  double  < δις dis twice  < δυο duo  two; genus Lazulena Mathews, 1918, kingfisher); "It is probable that another species, Halcyon winchelli Sharpe, though differing little in structure and not a great deal in coloration has had a different source, and that the apparent similarities are due to convergence. There is not, however, sufficient material and evidence to separate these species generically, so I class this with the preceding [Dilazula], but propose for it the new subgeneric name DILAZULENA as the bill is differently shaped: the red loral spots and red nuchal collar are distinctive: the upper-surface is more purplish above and the under-surface is buffy, whiter on abdomen, while specimens are known with the under-surface white, but whether this be sexual or due to immaturity is not yet known." (Mathews 1918).
