Classification provided by the World Register of Marine Species (WoRMS). [1565333<\/a>]<\/p><\/div>Taxonomic note:<\/strong>\u00a0The family Onchidorididae Gray, 1827 includes 5 genera:\u00a0Acanthodoris<\/em>\u00a0Gray 1827;\u00a0Adalaria<\/em>\u00a0Bergh, 1878;\u00a0Atalodoris<\/em>\u00a0Iredale & Donoghue; 1923,\u00a0Onchidoris<\/em>\u00a0Blainville, 1816; and\u00a0Onchimira\u00a0<\/em>Martynov, Korshunova, N. Samayan & K. Samayan, 2009; and includes a total of 56 currently accepted species (WoRMS, 2022). Except for the genus\u00a0Acanthodoris<\/em>, which includes 15 accepted species and three dubious ones (one\u00a0nomen dubium<\/em>\u00a0and two\u00a0taxa inquirenda<\/em>) (WoRMS, 2022; Hallas et al., 2016), and the recently described monospecific\u00a0Onchimira<\/em>\u00a0genus, represented by\u00a0Onchimira cavifera<\/em>\u00a0Martynov et al. (2009), the rest of the genera show a troubled systematic history. In fact,\u00a0Adalaria<\/em>,\u00a0Atalodoris<\/em>, and\u00a0Onchidoris<\/em>\u00a0(including respectively, 7, 17, and 16 currently accepted species) have undergone numerous revisions over the last few years, producing dissimilar systematic assessments, according to the different opinions of various authors (Hallas & Gosliner, 2015; Martynov et al., 2009). The validity of the genus\u00a0Adalaria<\/em>\u00a0is nowadays disputed; Hallas & Gosliner (2015) treated it as a synonym of\u00a0Onchidoris<\/em>\u00a0whereas Martynov et al. (2009) considered it as a valid genus. Furthermore, Hallas & Gosliner (2015) established the genus\u00a0Knoutsodonta<\/em>\u00a0to include all Onchidorididae without a rachidian tooth, but this diagnostic character was previously stated as the synapomorphy of the genus\u00a0Atalodoris<\/em>, originally described by Iredale and Donoghue (1923), and for this reason, was recently re-established by Ortea (2021) and is currently considered as valid.
\nAtalodoris albonigra<\/em> (Pruvot-Fol, 1951) was described in the Mediterranean Sea, but Furfaro et al. (2022) consider is is confused with Atalodoris pusilla<\/em> because its original description is totally insufficient to differentiate them. A. albonigra<\/em> was redescribed by Schmekel based on specimens from the Gulf of Naples by using the same general approach (Schmekel & Portmann, 1982), but some inconsistencies in the description support the possible synonymy with A. pusilla<\/em>. It was presumedly found again by Perrone (1986) but his description corresponded to A.pictoni<\/em>, as did other findings from the Ligurian Sea (Betti et al., 2017). Later A. albonigra<\/em> it was found in Catalunya, Spain (OPK, 2012), and these specimens really correspond to A. pusilla<\/em>, both in the molecular analysis and in the external morphology. In specimens so small (2.5 to 7.5 mm) the pigmentation of the mantle may appear with a prevalence of brown\/black, but with dark spots on a creamy white background in those specimens three times larger. Furthermore, the coloration and structure of gills and rhinophores match between the two taxa. Based on these considerations and on the fact that the samples described by Pruvot-Fol (1951), Schmekel & Portmann (1982) and Perrone (1986) are not available, Furfaro et al (2022) consider A. albonigra<\/em> as the junior synonym of A. pusilla<\/em>, according to ICZN rules.<\/p>\n
