Amphicorina pectinata (Banse 1957)

The evidence is inconclusive that Amphicorina pectinata is present in the Mediterranean. Attribution as such, eg Occhipinti-Ambrogi et al (2011) are more likely to be based on earlier misidentifications.

Based on the A. pectinata holotype re-examination and comments by López & Tena (1999), Italian specimens attributed to Amphicorina pectinata by Abbiati et al (1991) and Giangrande et al (1999) seem likely to belong to a different species. Amphicorina pectinata is unlikely to be an alien introduction to the Mediterranean, although reported as such by Occhipinti-Ambrogi et al. (2011) and elsewhere. Its type locality is a remote subantarctic island and the probability of its transfer from there by shipping to Italy seems very unlikely. There seems to be no arrival occurrence event date, before which the species was unknown from a well-surveyed area. Likewise the reverse transfer from Italy to subantarctic Auckland Island is improbable.
