Two new species of the genus Clathromangelia Monterosato, 1884 (Gastropoda Raphitomidae) from the Mediterranean Sea, with lectotype designation of C. granum (R.A. Philippi, 1844)

Notwithstanding few more or less recent contributions, taxonomy of the raphitomid extant species of the genus Clathromangelia Monterosato, 1884 (Gastropoda Caenogastropoda) remains almost controversial. Fossil materials revealed a wide diversity from Miocene to Pleistocene. Representatives in this genus seem to be almost exclusively Mediterranean, with only few doubtful taxa described for extra-Mediterranean localities. Species in the C. granum (R.A. Philippi, 1844) complex are here revised starting from the type material, among which the lectotype here designed. Two species are here described as new: C. fatamorganae n. sp. and C. martinastellae n. sp.
