First record of the genus Dermatobranchus van Hasselt, 1824, in the Mediterranean Sea (Nudibranchia: Arminidae)

Three individuals of a nudibranch belonging to the genus Dermatobranchus (Arminidae) were found at a depth of 3 meters, in a bottom with sand and gravel, during night SCUBA diving activity in Porto Pirrone, Leporano, Taranto, Apulia, Italy. The exter-nal morphology and coloration of these Mediterranean individuals clearly resemble those of D. rubidus (Gould, 1852), a species known only from the central and western Pacific Ocean. This is the first record of the genus Dermatobranchus van Hasselt, 1824 for the Mediterranean Sea
