HENICOPERNIS

(Accipitridae; Ϯ Long-tailed Honey Buzzard H. longicauda) Gr. ἑνικος henikos  singular; genus Pernis Cuvier 1817, honey buzzard; "3. ASTUR LONGICAUDA, Less.  The collection contains a female specimen of this rare bird, which has hitherto been supposed to belong to the subfamily Accipitrinæ; but the examination of this example proves that it would be more correctly placed in that of Milvinæ, as it possesses all the characters which are essential to that group. It forms part of the genus Pernis; but as it exhibits some slight differences in the wings, &c., from the type of the genus, I have ventured to propose the subgeneric appellation of Henicopernis, instead of adopting Dædalion (Dædalia), as suggested by Prince C. L. Bonaparte, because the latter word was long since given by Savigny as a more classical term for that of Astur." (G. Gray 1859); "Henicopernis G. R. Gray, Proc. Zoöl. Soc. London, 1859, p. 153. Type, by monotypy, Astur longicauda Lesson = Falco longicauda Garnot." (Peters 1931, 1, 198).
Synon. Daedalion.
