Type species Lepas hexastylos Fabricius, 1798 , by the subsequent designation of Pilsbry (1916 : 264 ). Included species Platylepas hexastylos ; P. decorata Darwin, 1854 ; P. ophiophila Lanchester, 1902 ; P. indicus Daniel, 1958 ; † P. wilsoni Ross, 1963 ; P. coriacea Monroe & Limpus, 1979 ; † P. mediterranea sp. nov. Remarks Following Utinomi (1970) and Hayashi (2013) , we consider Cryptolepas ophiophilus Krüger, 1912 (= Platylepas krügeri sensu Pilsbry 1916 ) to be a junior synonym of Platylepas ophiophila . Moreover, we concur with various authors (e.g., Monroe & Limpus 1979 ; Ross & Frick 2011 ; Hayashi 2013 ) in regarding Platylepas multidecorata Daniel, 1962 as a junior synonym of Platylepas decorata Darwin, 1854 . Range and distribution Early Pleistocene (Gelasian) to Recent. Recorded as fossil from the Lower Pleistocene (Gelasian) of Sicily , southwest Italy (present paper) and the Upper Pleistocene of Florida , southeastern USA († P. wilsoni ). Currently known as an epizoic phoront found on several marine vertebrates (such as turtles, sea snakes, sirenians and fish) occurring in tropical and warm-temperate seas (between ca 45° N and ca 45° S latitude).
