Diaphorodoris papillata  Portmann & Sandmeier, 1960

 Classification according to Bouchet et al. (2017)
Taxonomic source: World Register of Marine Species (AphiaID: 140631).
The specimens of this species can reach 10 mm in length. There is a very similar species D. luteocincta , also with a white body and a yellow bordered mantle. The difference with this other species is the presence of digitiform, deep red colored, thin and long papillae that could be dichotomized in the apex or near the base. These red papillae can be of different sizes and even have a rudimentary tubercule shape. A binocular microscope can show a whitish thin dotted design on the back, and mantle spiculation, less apparent than in D. luceocincta. Rhinophores are the white and long and have between 12 and 14 white lamellae, while the rhinophoric sheath has 1 to 3 little papillae on its upper edge . The eyes are located at the very base of the rhinophores. The gill consists of 5 semitransparent white leaves with a white pigmented rachis. The foot is white and ends in a tail that has a longitudinal dorsal keel pigmented opaque white. The mouth lacks labial palps and is surrounded by two large round bulbs instead.

This species is less common than D. luteocincta but they often share the same habitat, that is dimly lit rock walls with plenty of algae and sessile invertebrate fauna, specially bryozoans Smittina reticulata (see Ros, 1975 p:317) on which it feeds. It has also been quoted in Posidonia oceanica meadows and below stones. There are reports of Diaphorodoris papillata mating with Diaphorodoris alba in the Mediterranean. Being different species we assume this does not result on viable offspring, as we have never observed hybrid specimens either.


  • Diaphorodoris. Diaphanous or light colored Doris.
  • Doris. In Greek mythology, wife of Nereo, nymph of the waters and mother of Nereids.
  • Papillata. From Latin “papillātus”, having papillae or buds, shaped like a papilla or bud.

This recently described species mainly inhabits the western Mediterranean basin but is also found on the Atlantic coast of the Iberian Peninsula. It has been cited in the coast of Portugal and the Straits of Gibraltar, along the Mediterranean coast of Andalucia, on the eastern coast of Spain and in Catalonia. In the Catalan coast it is a relatively common species along the Costa Brava. It has also been cited in Italian waters, also in Malta, in the Croatian coast and recently in the eastern Mediterranean, off the coast of Israel. A report of this species at Taliarte, Gran Canària in 3 meters of water (27/08/2016, Jose Juan Calderín Peñate, pers. comm.) probably is the first confirmed cite for this species for the Canary Islands.  Citation by Cervera et al. (2004) in Cantabria (Northern coast of Spain) referencing the PhD Thesis by C. Ávila (1993) is not correct.
