Abstract - The Mediterranean Reicheiina with vanished pronotal prebasal edge, with description of a new genus from Sardinia (Coleoptera, Carabidae, Scaritinae, Clivinini) - The Mediterranean genera of Reicheiina without pronotal prebasal edge are here examined: Alpiodytes Jeannel, 1957; Catalanodytes Sciaky, 1989; Spelaeodytes Miller, 1863; Ichnusodytes Magrini, Fancello & Onnis n. gen.; the last here established for Typhloreicheia nivis Magrini & Onnis, 2018, species recently described from Sardinia [Mount Arcuerì (Nuoro)] [Ichnusodytes nivis (Magrini & Onnis, 2018) comb. nov.]. The study of the male and female genitalia, and exoskeletal characters, does not reveal close phyletic relationships between these taxa. Important discrepancies are found in the descriptions of the monospecific genus Catalanodytes and its type species C. bellesi (Lagar Mascaro, 1971): the superior labrum has 5 marginal bristles, not 3, and the elytral marginal furrow ends at level of the base of the fifth stria, not second. Reflections on the issues regarding the evolutionary developments which have involved the representatives of the subtribe Reicheiina close the article.
