The genus Cordulegaster is represented in Sicily by two species. From an examination of material recently collected there and from evidence in the literature it is concluded that one has previously been misidentified, here named C. boltonii trinacriae ssp. nov.: the other is the little-known C. bidentatus sicilicus Fraser, 1929. A key to males of the Old World species of Cordulegaster is provided and lectotypes for C. boltonii algiricus Morton, C. princeps Morton, C. insignis amasinus Morton, C. insignis nobilis Morton, C. coronatus Morton and a neotype for C. charpentieri (Kolenati) are designated.
