The specimens and description of Sabellaria spinulosa var. alcocki by Fauvel (1927) were examined by da Cunha Lana and Gruet (1989) and found to contain several species, some belonging to Sabellaria wilsoni Lana & Gruet, 1989. Thus, specimens identified using Fauvel's key probably belong to other species. Lezzi et al. (2015) suggest that specimens recorded as Sabellaria alcocki in the Mediterranean belong to juveniles of Sabellaria spinulosa (Leuckart, 1849) and that Sabellaria alcocki is absent from the region. Schimmenti et al. (2015) show through molecular analyses that specimens identified as Sabellaria alcocki from Italy fully matched the cytochrome c oxidase subunit I (COI) sequences of Sabellaria spinulosa .
