Hypselodoris violacea Gosliner & R. Johnson in Epstein et al., 2018

This newly described species of Hypselodoris is known from the Philippines and Malaysia. It is one of more than a dozen new Hypselodoris' described in Epstein, H.; J Hallas; R. Johnson; A. Lopez & T.M. Gosliner, 2018. The body is deep violet-purple with a wide white marginal band. Michael's shots here are of a deep purple-blue specimen. The rhinophores and gill are the same as the body color.

A similar species is described in this same paper. Hypselodoris variobranchia differs in that it has bright orange rhinophores.

Looking forward to seeing more of the newly named critters in future BOW's.

The Indo-Pacific represents the largest expanse of tropical ocean in the world, stretching from the Indian Ocean coast of southern Africa and the Red Sea to the central Pacific of the Hawaiian Islands, Easter Island and the Marquesas.

This region supports the most diverse marine fauna of any place in the world for most groups of marine organisms. The nudibranchs and sea slugs are no exception to this rule; there are about 3,000 described species of these organisms in the world and at least 40% of these have been found exclusively in the Indo-Pacific tropics. This book illustrates 2,138 Indo-Pacific nudibranchs and sea slugs, including many undescribed species.
