Leucocirca

(syn. Rhipidura Ϯ Willie Wagtail R. leucophrys) Gr. λευκος leukos  white; κερκος kerkos  tail; "The next modification of form, or sub-genus, we have named LEUCOCIRCA, from the circumstance of several of the species having more white about their tails than any other fly-catching birds yet discovered.  ...  Considering, however, the remarkably small and universally compressed bill of Rhipidura, as seen in R. flabellifera, as the most obvious, if not the real typical, character of that division, we place under Leucocirca all others which have the bill more lengthened, broader at the base, and less compressed towards the tip; the bristles at the corners of the mouth, although very rigid and often much lengthened, are not so long as the bill; the tail, in both, is the same, but in this the feet are more developed; and in one species (L. laticauda), which is probably the type, particularly long and stout. We can hardly suppose that none of these species have been described; but as they do not appear to be figured, excepting, indeed, the M. Javannica by Sparman (Mus. Carl. pl. 75)" (Swainson 1838); "Leucocirca Swainson, Naturl. Lib. (Jardine), vol. x. Flycatcher, p. 126, pl. xi. May 19th, 1838.  Type (by monotypy): L. laticauda Sw. = Turdus leucophrys Latham." (Mathews 1930); "Leucocirca Swainson, 1838, Flycatchers (Jardine, ed., Naturalist's Library, 21, Ornith., 10), p. 126, pl. 11. Type, by subsequent designation (G. R. Gray, 1840, List Gen. Birds, p. 32), Leucocirca javanica (Sparrman)" (Mayr in Peters 1986, XI, 530).
