(Trochilidae; Ϯ Ecuadorean Piedtail P. hemileucurus) Gr. φλοξ phlox, φλογος phlogos flash of lightning, gleam; φιλος philos lover; "PHLOGOPHILUS HEMILEUCURUS, Gould. ... Remark.—I have no doubt that the bird from which the above description was taken is immature; when the adult is discovered, it will probably be found to be a very remarkable species; in fact, the specimen described exhibits characters differing from those of every other known Humming-bird, among which its singularly-marked, rounded tail is especially noticeable." (Gould 1860); "Phlogophilus Gould, Proc. Zool. Soc. London, pt. 28, 1860, p. 310. Type, by monotypy, Phlogophilus hemileucurus Gould." (Peters 1945, V, 86).
