Classification provided by the World Register of Marine Species (WoRMS). [744313<\/a>]<\/p><\/div>Taxonomic note<\/strong>: In the description of the species by Schmekel & Capellato (2001), authors referred to a single anatomically studied specimen, 1.2 mm long when alive, as having a radular formula of 3 x 1.0.1, which is considered by the authors as the rudimentary radula of a juvenile. They found no internal shell nor could recover any gastric plates after treating the sample with NaOH. These features induced Ortea (2013) to propose the provisional inclusion of this species in the genus Pseudoilbia<\/em> within the Ilbidae family, including species of the genus\u00a0Ilbia<\/em> Burn, 1963 and Pseudoilbia<\/em> Miller & Rudman, 1968 with no gastric plates within their digestive tract and the second genus also without spinal tooth. Specimens studied by Araujo et al (2022) were characterized by features consistent with the original description of R. avellana<\/em> (sensu<\/em> Schmekel & Cappellato, 2001), like the shape of the body, presence of a round brownish mark on the centre of tail, general colour pattern, absence of gizzard plates and presence of gills, specimens collected at Roses (Spain) about 45 km from the type locality, and clustered in the phylogenetic analyses among species of the genus Runcina<\/em>, questioning the assignment by Ortea (2013). Moreover, the lack of rachidian teeth in R. avellana<\/em> reported by Schmekel & Cappellato (2001) might be an artefact since only one apparently juvenile specimen was studied by these authors. Unfortunately, Araujo et al (2022) were not successful on obtaining the radula for study so, in the meantime, at\u00a0OPK we prefer\u00a0to keep the species <\/span>R.avellana<\/em> within the genus <\/span>Runcina<\/em> until further studies of other specimens that may appear in future allow confirmation of the inclusion in one or another genus.<\/span><\/p>\n
