Hypselodoris regina Ev. Marcus & Er. Marcus, 1970
This nudibranch was described from a specimen collected among corals at a depth of 2 m at Nosy Tanikely, south of Nosy Be, Madagascar.
Hypselodoris regina has an orange body with typically three longitudinal black lines separated by two elongated orange spots, and a white background on the back. The mantle has a continuous or interrupted orange border. The gills and rhinophores are orange, sometimes edged in white.
This species is very similar in color to species of the Chromodoris quadricolor color group such as Chromodoris hamiltoni and Chromodoris elisabethina, with three black or dark purple longitudinal lines, a bluish background and an orange border. Due to its internal anatomy, it differs significantly from a Hypselodoris species. Details of the color pattern characteristic of this species are the ring formed by the central black line anteriorly between the rhinophores and the diffuse orange longitudinal markings on either side of the central black line. The bluish-white gills have a triangular cross-section and are outlined in orange. Distinctive white spots can sometimes be seen on the outside.
The colorful slug was observed eating sponges from the genus Dysidea.
