DEFINITIONS

MYIOBIUS
(Tityridae; Ϯ Whiskered Flycatcher M. barbatus) Gr. μυια muia, μυιας muias  fly; βιος bios  living, livelihood; "MYIOBIUS. G. R. Gray.  TYRANNULA. Swains.  Mr. Gould has adopted for the following species Mr. Swainson's generic appellation of Tyrannula, but Mr. G. R. Gray has pointed out that as Tyrannulus was proposed and published eleven years before, namely in 1816, by Vieillot, it becomes necessary to change the former name, and therefore he proposes Myiobius.    1. MYIOBIUS ALBICEPS. G. R. Gray.  Muscipeta albiceps. D'Orb. et Lafr. Mag. de Zool. 1837, p. 47.  ...  2. MYIOBIUS AURICEPS.  Tyrannula auriceps. Gould, MS.  ...  3. MYIOBIUS PARVIROSTRIS.  Tyrannula parvirostris, Gould, MS.  ...  4. MYIOBIUS MAGNIROSTRIS. Tyrannula magnirostris. Gould, MS." (Darwin 1839); "Myiobius Darwin, 1839, Zool. Beagle, 3, Birds, p. 46. Type, designated by International Commission, Muscicapa barbata Gmelin.  ...  For use of this name in its accustomed sense see 1956, Op. Decl. Int. Comm. Zool. Nomencl., 13, p. 245" (Traylor in Peters 1979, VIII, 116).  It has been suggested that this genus, together with Onychorhynchus and Terenotriccus, be moved to the Oxyruncidae.
