Description
Ground colour milky white, with large orange-yellow to red tubercles distributed across the dorsum. Rhinophores are the same colour as the tubercles, or slightly darker. The gills are large and white, with rachises matching the tubercle colour. The mantle margin is indistinct in the original material, with the gill ring sitting near the middle of the dorsum. Reaches 60 mm. A predator of other heterobranchs, including Chromodoris annae, Goniobranchus reticulatus, Hypselodoris festiva and Hypselodoris emma.Distribution
Indian Ocean and western Pacific. Records include South Africa, Tanzania, Réunion, Oman, Singapore, Australia, New Caledonia, Indonesia, Malaysia, the Solomon Islands, the Philippines and Japan. The type locality is El-Tor on the Sinai Peninsula, Red Sea.Etymology
The specific epithet impudica is the Latin feminine of impudicus, "shameless" or "immodest".Remarks
Originally described as Doris impudica by Rüppell & Leuckart (Atlas zu der Reise im nördlichen Afrika, Wirbellose Thiere, p. 33, 1830) from a single specimen collected at El-Tor in April. The diagnosis emphasises the indistinct mantle ("pallio indistincto") and the central placement of the twelve pinnate gills — features that anticipate the later transfer to Gymnodoris Stimpson, 1855. Yonow 2011 treated the western Pacific Gymnodoris rubropapulosa (Bergh, 1905) as a junior synonym, although some researchers retain it as distinct on the grounds that G. impudica is a Red Sea species.References
