Since, according to Halffter and Martínez (1968: 246), the typeof  C. minutuscannot be found and there are more small species fitting Laporte’s description, there are no grounds to make this assumption. Still, several authors ( Balthasar 1941c: 344; Vulcano and Pereira 1964: 585) have considered  C. minutusa synonym of  S. minuta. We consider  C. minutaa species inquirendum. See also the remark in Halffter and Martínez (1968).
