The rhinophores are coloured dark red with a whitish tip. The oral tentacles are\u00a0short and grooved. The gill has 3 tripinnate non-retractile leaves, with an orange-reddish rachis and whitish or yellowish\u00a0branches. There are lateral slots below the rhinophores.

Salera, pers. comm.) and in Malta (Island of Gozo, 06\/19\/2015: H.

The easternmost reports are from the island of Samos, Greece, of two specimens in 8 meters of water (Tatjana Stockmann & Benjamin Gundacker) found in September 2020; also Poursanidis & Gubili {in} B\u00e1ez et al (2025) report 2 findings in 22 meters depth on Posidonia oceanica<\/em> at National Marine Park of Alonissos, Greece in June 2021, and one specimen at 10m depth on Chondrosia reniformis<\/em> at Plakias, Southern Crete, Greece in October 2021. <\/div>\n

Peels in K\u00f6hler, 2016; 06\/19\/2015, H. Domnick in K\u00f6hler, 2016). An observation at 50 meters deep by Elena Bretaudeau in Pota del Llop (Illes Medes) in 2024 confirms the presence in Catalan waters, although always at depth. A report from Mallorca (S\u00f2ller, 12\/4\/2016: L. Juskani\u010dov\u00e1, pers. comm.) in 45 meters of water, and a recent report (Enric Ballesteros, Pers.Comm.) in september 2020 at Na Foradada (Cabrera, Spain) in 35 meters of water confirms the stable presence of the species in the Balearic Islands. The easternmost reports are from the island of Samos, Greece, of two specimens in 8 meters of water (Tatjana Stockmann & Benjamin Gundacker) found in September 2020; also Poursanidis & Gubili {in} B\u00e1ez et al (2025) report 2 findings in 22 meters depth on Posidonia oceanica<\/em> at National Marine Park of Alonissos, Greece in June 2021, and one specimen at 10m depth on Chondrosia reniformis<\/em> at Plakias, Southern Crete, Greece in October 2021. <\/div>\n
Distribution\n<\/strong>It is a very recently described species, based on specimens found on the island of Mallorca (Oceanographic Campaign DRAGONSAL 2014) and Malta (Fom Ir-Rih, 07\/07\/2014: C. Mifsud in Sammut, 2016). On the coast of Granada (La Herradura, 6\/12\/2013: F. Aguado, pers. comm.), on the Italian coast (Secce di Tor Paterno, 08\/30\/2014: G. Salera, pers. comm.) and in Malta (Island of Gozo, 06\/19\/2015: H. Domnick in K\u00f6hler, 2016) there were reports\u00a0of Martadoris limaciformis<\/em> (Eliot, 1908) which have now been assigned to Martadoris mediterranea<\/em> (Dom\u00ednguez et al., 2015). The observation of a specimen of this species and 7.9 cm long in the Cap Norfeu, Roses, Spain, on the Eunicella singularis<\/em> gorgonian at 48 m depth (9\/11\/2015: J.M. B\u00e1\u00f1ez and J. Barcia, GROC), extends its distribution in the Iberian Mediterranean coast, as well as its maximum recorded size, which so far was 20 mm (23\/09\/2006: G. & P. Peels in K\u00f6hler, 2016; 06\/19\/2015, H. Domnick in K\u00f6hler, 2016).
