Cymatium corrugatum (Lamarck 1816) Gastropoda, Prosobranchia. A new species for the Adriatic

Very valuable papers concerning malacology of the Adriatic Sea deal, for the most part, with the systematics, whereas, on the other hand there is a substantial number of papers with very scarce information on the ecology of individual species. Since I intended to provide some more comprehensive data on individual species, rather complex bionomic and biocoenological research was undertaken aiming at studying taxonomy and ecology of the Prosobranchiata group. Present research covered different biotopes of the northern, middle and southern Adriatic, both in the shallow coastal and deeper open littoral, and hard and mobile bottoms. Material was collected by two methods: 1. SCUBA diving or direct collection and observations and 2. an indirect method of collection of samples by Petersen grab, dredge and trawl. Throughout years of investigations of the coastal and open Adriatic, the species Cymatium corrugatum was recorded only from the vicinity of the Vis and Hvar islands, at 60 and 80 m depths. It was found in the biocoenosis of detritic bottoms of the open sea and biocoenosis of coastal detritic bottoms. Cymatium corrugatum is a new species for the Adriatic and therefore it should be included into the register of the Gastropod fauna of the Adriatic Sea.
