External morphology

Shell external, translucent, background colour light brown to grey with dark brown, white and orange punctuations surrounded by small dark red points. Parapodia lighter in colour. Head lighter in colour, area around eyes pigmented.

Ecology

Specimens were found crawling on calcareous rocks with green algae of undetermined species during night samplings. Egg masses were observed in November and juveniles in December 2017. Egg masses elongated, forming a ‘C’, with white eggs ( Figure 1 View Figure 1 (c)).

Distribution

Azores, Atlantic Spanish coast: Canary Islands; Mediterranean Spanish coast: Andalucía, Levantine coast ( Cervera et al. 2004), Catalonia (this study); Mediterranean French coast ( Garabedian et al. 2017; this study); Greece and Italy ( Garabedian et al. 2017).

Remarks

Haminoea species in the Mediterranean are understudied ( Crocetta et al. 2015; Micaroni et al. 2018) and, thus, all morphological characters that may be useful in distinguishing species are not always clear. One visible distinguishing feature of this species is the presence of a pigmented periocular area. The presence of small orange dots under the shell surrounded by smaller dots of dark purple or black colour, forming a flower pattern, was found in all studied specimens.
