It contains a single species, C. bellottii Anisian –Ladinian -aged Besano Formation of Monte San Giorgio area (Swiss-Italian borderland),[ 3] Prosanto Formation of canton Graubünden , Switzerland, and possibly the late Ladinian Alcover Unit of Spain.[ 2] [ 4] [ 5] Strelovec Formation of Slovenia .[ 6] C. hattichi Bürgin & Herzog 2002 ) from the Prosanto Formation was previously placed in this genus, but a 2009 study placed it in the new genus Luopingichthys [ 7]
