Species complex. Salazar-Vallejo (2017) revised the genus Brada and transferred a large number of species (including Brada villosa ) to Bradabyssa Hartman, 1967. Previous descriptions of Bradabyssa villosa by e.g. Fauvel (1927) , comprise a wide variety of characters and probably comprise more than one species under this name ( Salazar-Vallejo 2017 ). Likewise, molecular analyses by Carr et al. (2011) revealed at least two putative cryptic species in Canadian waters (one in the Arctic, another in the Pacific Ocean) which were initially identified as Bradabyssa villosa . Salazar-Vallejo (2017) restricts Bradabyssa villosa sensu stricto to the North Atlantic Ocean and European and Russian Arctic and re-instates Bradabyssa parthenopeia (Lo Bianco, 1893) from the Mediterranean (Gulf of Naples) - a species previously considered a synonym of Bradabyssa villosa . It is highly likely that Bradabyssa villosa i s absent from the Mediterranean and specimens from this region belong to other species such as Bradabyssa parthenopeia .
