Hello Bill,
I found this nudibranch and I have identified as Chromodoris africana but I am having some doubts as it presents orange lines between the black ones.
Locality: Ponta do Ouro, 16 meters, Moçambique, Indian Ocean, 1 November 2007, rocky bottom. Length: about 30 mm. Photographer: David Abecasis.
Best regards,
David Abecasis

Dear David,
This is one of the group of species with black longitudinal lines which we call the Chromodoris quadricolor group, not because they are closely related to each other, but simply because they all look quite similar. The relatively narrow and high body shape of this species suggest it is a species of Hypselodoris rather than a Chromodoris and it is in fact Hypselodoris regina. The way the central black line forms a loop inside the rhinophores is quite characteristic of this species, as is the shape of the gills - triangular in cross section.
Best wishes,
Bill Rudman
