This paper is dedicated to Guðmundur Vidir Helgason who
passed away on 9 May 2020, just before publication of
this paper. Project Manager at RORUM, an environmental
research and consulting company, he was previously a
Project Coordinator for the BIOICE program (Benthic
Invertebrates of Icelandic Waters) and Director of the
Sandgerði Marine Centre from 1992 to 2013, being
one of the organizers of the 7th International Polychaete
Conference (Reykjavík, July 2001).

Abstract. Based on samples collected during the BIOICE project off Iceland, four species of marine
annelids belonging to the family Pectinariidae were identifi ed: Amphictene auricoma (O.F. Müller,
1776), Cistenides granulata (Linnaeus, 1767), Cistenides hyperborea Malmgren, 1865 and Lagis
koreni Malmgren, 1866. Taxonomic remarks and data on geographical and bathymetric distribution are
presented. The distribution of each species off Iceland was evaluated and two patterns were defi ned:
C. granulata and C. hyperborea were mainly found in waters off the northeast coast, while A. auricoma
and L. koreni were found on the southern coast. Several body characters with taxonomic value in this
family were reviewed under the stereo microscope and scanning electron microscope, with special
emphasis on the neuropodial uncini. Remarks on these special chaetae are included in the diagnoses.
