Rostanga is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.^[2] Some sources, such as The Sea Slug Forum still classify Rostanga in the family Dorididae.

Phylogeny

A phylogenetic analysis shows that the species Rostanga aureamala, Rostanga elandsia, Rostanga pepha and Rostanga setidens form a sister group with the other species in this genus. The species from Japan and the Marshall Islands form the basal clade. The species from the tropical Indo-Pacific are not monophyletic. The species from the Atlantic Ocean and the Eastern Pacific from a clade that is a sister group to R. australis. The Indo-Pacific species Rostanga bifurcata forms a sister group to Rostanga dentacus.^[3]
