A series of Calchas specimens from the Greek island of Megisti (= Kastelorizo) was examined. It is shown by detailed analysis of several key diagnostic characters that this population from Megisti Island belongs to C. gruberi Fet, Soleglad et Kovařík, 2009. Therefore, C. nordmanni Birula, 1899 is not present in Greek fauna. The population of C. gruberi from Megisti comprises the largest specimens so far reported.
