ABSTRACT The door snail Siciliaria (Siciliaria) scarificata (L. Pfeiffer, 1856) (Pulmonata Clausiliidae)
is redescribed. The species is endemic to Marettimo (Egadi Islands, Sicily, Italy) and it is
the only one of the genus Siciliaria Vest, 1867 living in this island. Siciliaria scarificata can
be morphologically identified by the presence of a high columellar lamella, ascending in a
double “S” curve, a wide anterior upper palatal plica, long basal plica, sulcalis present;
clausilium plate distally less narrowed; genitalia are characterized by very short bursa
copulatrix duct; short diverticulum of bursa copulatrix; penial papilla conic and short. Notes
about its taxonomy, biology and conservation status are also provided.
