Genus BRACHYRHINUS Latreille (1802). 



Brachyrhinus Latreille, Hist. Nat. Gen. et Part. Crust et Ins., vol. 3, 1802, p. 200. 

 Otiorhynchus Germar, Ins. Spec. Nov., 1824, p. 343. 



The type of the genus is ligustici Linnseus, designated by virtue of 

 ehmination by Latreille (1807) and Bedel (1881). Latreille's (1810) 

 designation of viridis as type is not acceptable as that species was 

 not originally included. The type of Otiorhynchus is clavipes (Olivier) 

 Bonsdorff designated by Schonherr (1826) and is congeneric Math 

 ligustici, but represents a different subgenus.
