Author & date of last revision: admin on 20 November 2011
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.
