Pretty similar are:
Hypselodoris sp. 07 which differs by the colour of the gills
Hypselodoris bullocki which differs by the pale pinkish background colour, and by thin white marginal band
Hypselodoris apolegma which differs by the purple colour, and by the reticulate white edging of the mantle.
Thorunna halourga which differs by the broad white mantle margin, and by the low gill pocket.
This picture shows a specimen mating Hypselodoris sp. 07, this indicates they are most probably the same species, I keep them seperate for now.
