The presence of Oxychilus (Ortizius?) clarus (Held) on Corsica is reported for the first time. Anatomical study has confirmed that, although distinct, this species is close to O. (Ortizius?} perspectivus (Kobelt) of southern Italy. Comparisons are given with O. hydatinus (Rossmässler), which is placed in a separate suhgenus Mediterranea Clessin 1880 with Riedelius Hudec 1961 as a junior synonym.
