Description
The animals of this species can reach 40 mm in length. The general coloration, although it can vary among specimens, is a golden-yellow background or brown in the center of the back and golden-yellow in the margin of the mantle. The back is decorated by numerous white lines that crisscross irregularly that surround small mantle hemispherical tubercles. In young specimens the white lines may not be visible yet and instead there are several opaque white circular spots surrounding the tubers, two or more of these spots could join to form a bigger single one. The ventral mantle is very spiculous, with spicules forming irregular chambers. The rinophores are yellow, of a slightly paler shade than the color of the body, and the laminar base is semi-transparent. The gill consists of 4-6 tripinnate leaves colored pale yellow. The foot is narrow and spiculous, with spicules arranged transversely. The mouth lacks the labial palps as with all Dendrodorididae.

Biology
D.areolata is often found under stones, with sponges and brotrillids, from the tidal zone to circalitoral zone, where it’s usually found among commercial fish bycatch. The spawn is yellow and is composed of a 4 mm height ribbon, spirally wound 2-3 times. Eggs are yellow and with a size of 100 microns enclosed in a 130 microns ovigerous capsule.

Etymology

  • Doriopsilla, genus described by Rudolf Bergh in 1880 in his paper “Die Doriopsen des Mittelmeeres”. Doriopsilla derives from Doris, a sea nymph in the Greek mythology + “-opsis”, “similar to” o “shaped like” + “-illa”, a diminutive. The final meaning would be “shaped like a small Doris”.
  • Areolata is derived from Latin and means “net-like”, referring to the white line pattern of the dorsum.

Distribution
This species has been cited by the names of D. evanae, D.ciminoi and D. pusilla, which are currently considered synonyms of D.areolata. It is found in all European shores, both Atlantic and Mediterranean, as well as in all areas of the Iberian Peninsula, Balearic islands and Canary islands. It has also been cited in Cape Verde and Senegal.
