Taxonomic note: The European Atlantic and Mediterranean species of the genus Chromodoris and Hypselodoris have been reconsidered. After molecular analysis of the Chromodorididae performed by Johnson & Gosliner (2012, Traditional taxonomic groupings mask evolutionary history: A molecular phylogeny and new classification of the chromodorid nudibranchs. PLoS ONE 7(4): 33479) the Hypselodoris species have been included in the genus Felimare Ev. Marcus & Er. Marcus, 1967 and the Chromodoris species have been included in the genus Felimida Ev. Marcus, 1971.

- Hypselodoris bilineata (Pruvot-Fol, 1953)
Description
It can reach 25 mm in length. Long and narrow dark blue body, with a yellow line that runs around the margin of the notum. The specific name is due to a double yellow middle dorsal line that goes from the back of the rhinophores to the gills; this line forms a wide arc in front of the rhinophores and surrounds the gill sheaths, extending a little behind them. Rhinophores and gill leaves are also blue, with yellow dorsal spines. On the sides of the body, a continuous yellow line and other discontinuous lines below it that continue irregularly to the tail. The foot is also bluish in color and forms a pair of triangular propodial tentacles. The mouth has a pair of short oral palps.
Biology
It lives in rocky substrates with abundance of algae, hydrozoans and the sponges it feed on.
Etymology
- Bilineata. From Latin “bi”, two + “linea”, line, stripe.
Distribution
This species has been reported on the Atlantic coast of Morocco, Madeira, the Canary Islands, the Balearic Islands and the entire Iberian Peninsula coast from Portugal to Catalonia. It is a relatively frequent species in the south of the Catalan coast, but it has also been observed in certain locations of the Maresme and the Costa Brava (where it is rare).
