DEFINITIONS

SAXICOLA
(Muscicapidae; Ϯ Common Stonechat S. torquatus rubicola) L. saxum, saxi  stone; -cola  dweller  < colere  to inhabit; "Gattung. Steinschmätzer. Saxicola.   ...  Sie machen den schicklichsten Uebergang zu den Fliegenfängern nach Gestalt und Lebensart; nisten auf der Erde oder in Löchern, und fressen blos Insekten, und zwar Käferarten und Fliegen.  *1. Großer Steinschmätzer (S. Oenanthe).   ...  *2. Braunkehliger Steinschmätzer (S. Rubetra).   ...  Ϯ3. Schwarzkehliger Steinschmätzer (S. Rubicola)" (Bechstein 1802); “Bechstein’s genus Saxicola  ...  contains three species only: œnanthe (Wheatear), rubetra (Whinchat), and rubicola (Stonechat). No type was originally designated, but Swainson (Zoologist Journ. iii. 1827, p. 172) subsequently fixed as the type Motacilla rubicola. Gray in 1841 and Seebohm (Cat. Bds. B. M. v. 1881, p. 362) made “œnanthe” the type; there can be no doubt, however, that Swainson’s designation must stand, and another name be found for the Wheatears” (BOU 1915); "Saxicola Bechstein, 1803, Orn. Taschenb., (1802), p. 216. Type, by subsequent designation (Swainson, 1827, Zool. Journ., 3, p. 172), Motacilla rubicola Linnaeus." (Ripley in Peters 1964, X, 104). Some workers believe that this form could be split into as many as seven species (i.e. S. torquatus, S. rubicola, S. maurus, S. przewalskii, S. stejnegeri, S. albofasciatus, S. sibilla).  
Var. Laxicola.
Synon. Curruca, Fruticicola, Pratincola, Rhodophila, Rubetra.
● (syn. Oenanthe Ϯ Northern Wheatear O. oenanthe) Formerly this name was much used for the wheatears and similar chat-like species (see above).
