Umbellisyllis fasciata Sars, 1869: 254; Sars 1872: 41 –45.

Material examined. Norway: 2 spms, Trondheim, 63°28.36' N 10°00.04'W, m, shells, dead Lophelia, gravel, Jan 2002.

Remarks. Starting with Hartman's catalogue (1965), the name Umbellisyllis is sometimes used as a senior synonym to Virchowia . This is not correct, from the detailed description by Sars (1872), it is clear that U. fasciata is a member of Odontosyllis, possibly close to Odontosyllis gibba .
