Dasyskenea dibellai n. sp. from the Central Mediterranean Sea (Gastropoda Vetigastropoda Skeneidae)

Dasyskenea dibellai n. sp. from the central Mediterranean Sea, collected off Marsala, Western Sicily, 133 m depth, in the Muddy Detritus Biocoenosis, is here described. The new species, characterized by small size, an almost planorbid profile and an evident transverse sculpture prevailing over the longitudinal one, is compared with the Skeneidae with such characteristics both from the Mediterranean Sea and the adjacent Atlantic Ocean. Due to the characteristics of the protoconch and the morphological affinity, the new species is assigned to the genus Dasyskenea Fasulo et Cretella, 2003 together with Skeneoides digeronimoi La Perna, 1998 and the two North-East Atlantic related species, Skenea nilarum Engl, 1996 and S. victori Segers, Swinnen et De Prins, 2009. In the context of comparisons, Skenea costulata Sbrana et Siragusa, 2018 is considered probable synonymous with Skenea divae Carrozza et van Aartsen, 2001.
