Classification provided by the World Register of Marine Species (WoRMS). [1541498<\/a>]<\/p><\/div>Taxonomical note: <\/strong>Korshunova et al (2021) published their work on the Polycera quadrilineata<\/em> cryptic complex, where four species from the European Atlantic shores were recognized based on a multidisciplinary approach (molecular, morphological, phylogenetic, phylogeographical and ecological) to species determination. In this work, the authors determined that Polycera faeroensis<\/em> reports included another cryptic species (new to science) that they have named Polycera kernowensis<\/em>, that can be easily determined by the shape of the structure protecting the gills, one pair of single lateral processes without tubercles in P. kernowensis<\/em>, and one pair\u00a0 of wing-like lateral lobes with multiple small tubercles or extensions in P. faeroensis<\/em>. Moreover, P. kernowensis<\/em> usually has less than nine appendages of the frontal veil, while P. faeroensis<\/em> has commonly more than nine frontal appendages, among other anatomical differences.<\/p>\n

Description
\n<\/strong>Body with a maximum length of 20 mm, translucent white, in which the visceral mass is visible by transparency. It has a frontal veil on the head with up to 9 finger-like cephalic processes coloured yellow. Rhinophores have between 14 and 15 lamellae with a documented maximum of 22 (Korshunova et al. 2021) with yellow tips. The gills have between 4 and 7 unipinnate or partially multipinnate white leaves with yellow tips. The gills are flanked by a single lobe, without tubercles or any kind, coloured white with a yellow distal end. The foot is narrow, translucent white, with a yellow edge at the end of the tail where it joins with a thin mid-dorsal yellow band of the same colour. In its anterior part it is slightly notched in the middle, and has two propodial yellow tentacles, slightly thickened to form a double edge. Eyespots are located on the notum, behind the rhinophores, on a light coloured area.<\/p>\n

Biology
\n<\/strong>Polycera kernowensis<\/em>\u00a0is common in shallow-water, as it has been found from 8 to 30 m, on stony and muddy substrates. It feeds on bryozoans Bicellariella ciliata<\/em> and Scrupocellaria<\/em> spp.<\/p>\n
