Chromodoris luteopunctata (Gantès, 1962), originally described from Morocco, is very similar to Chromodoris luteorosea. It is known from the Gibraltar Straits area, North Africa, and the Canary Islands. It is reported on the Forum from Senegal.

The body and mantle are translucent violet, with some darker zones on the mantle. There is a broad yellow band around the mantle edge, inside of which is a thin brownish red zone, and inside this a broad bluish band. The reddish zone seems to be caused by the overlapping of the yellow and violet pigments and the broad inner bluish band is caused by the underlying opaque white mantle glands being obscured by the violet pigmentation of the mantle skin. The blue band then varies from animal to animal depending on the development of the mantle glands. The mantle is covered with scattered opaque white and yellow spots of varying sizes. Usually the inner ones are small and white and the outer ones larger and yellow. But sometimes there are small yellow spots, or large white spots with a yellow centre. Smaller specimens usually have less violet pigmentation and so appear a translucent violet-grey. In small specimens the mantle glands are less obscured and so their reticulate, branching nature is more obvious than in larger animals [see lower photo]. The body is translucent violet with small whitish spots. There is a thin opaque white line around the anterior part edge of the foot which thickens about halfway down the foot. The rhinophores are reddish-violet, darker towards the tip, but with a translucent white tip. The lamellae on the rhinophore club have small bluish white spots in adults, but these are absent in juveniles. The gills are similar in colour to the body, and have the same small whitish spots found on the rhinophores.

The small white spots on the gills and rhinophores have previously been considered a good charcter separating this species from C. luteorosea, but there are many photos on the Forum showing similar spots in specimens of that species. The shape, size and colour of the spots on the mantle has also been used to separate these two species. C. luteopunctata is said to have small, irregular yellow spots in the center of the mantle, and larger spots on the mantle margin. But often the small spots are white and the larger spots are white with a yellow centre. C. luteorosea on the other hand has a fairly even scattering of large spots [white with yellow centre] interspersed with a few small white or yellow spots. The only consistent difference seems to be that in C. luteorosea large spots have a smooth round edge while in C. luteopunctata the edge of larger spots is very irregular [See Alma Sanchez's message].
