Two Platyla species from Sardinia (Gastropoda: Prosobranchia: Aciculidae)

Recent field work led to the discovery of two Platyla species in Sardinia where no aciculids had hitherto been reported. One of these species, P. sardoa n. sp., is similar to the fossil P. klemmi from the Lower Pliocene of Celleneuve near Montpellier (France) and the Upper Pliocene of the Rhine Valley (Germany) and to the recent P. lusitanica from southern Portugal. It has a reduced range in the central-eastern part of the island, but it is locally frequent. The other species, Platyla sp., recalls P. gracilis, P. cryptomena and P. microspira. It is easily distinguished from the first two species, but its relationship with the last is difficult to define. Although it has a wider range than the other species, it is locally rather scarce.
