The polychaetes of the order Phyllodocida (excluding Nereidiformia and
Phyllodociformia incertae sedis) collected from deep-sea habitats of the Iberian
margin (Bay of Biscay, Horseshoe continental rise, Gulf of Cadiz and Alboran Sea),
and Atlantic seamounts (Gorringe Bank, Atlantis and Nameless) are reported herein.
Thirty-six species belonging to seven families – Acoetidae, Pholoidae, Polynoidae,
Sigalionidae, Glyceridae, Goniadidae and Phyllodocidae, were identified. Amended
descriptions and/or new illustrations are given for the species Allmaniella
setubalensis, Anotochaetonoe michelbhaudi, Lepidasthenia brunnea and Polynoe sp..
Relevant taxonomical notes are provided for other seventeen species. Allmaniella
setubalensis, Anotochaetonoe michelbhaudi, Harmothoe evei, Eumida longicirrata
and Glycera noelae, previously known only from their type localities were found in
different deep-water places of the studied areas and constitute new records for the
Iberian margin. The geographic distributions and the bathymetric range of thirteen
and fifteen species, respectively, are extended. The morphology-based biodiversity
inventory was complemented with DNA sequences of the mitochondrial barcode
region (COI barcodes) providing a molecular tag for future reference. Twenty new
sequences were obtained for nine species in the families Acoetidae, Glyceridae and
Polynoidae and for three lineages within the Phylodoce madeirensis complex
(Phyllodocidae). A brief analysis of the newly obtained sequences and publicly
available COI barcode data for the genera herein reported, highlighted several cases
of unclear taxonomic assignments, which need further study.Thanks are due to the chief-scientists, scientific parties and crews of the 17 cruises
that originated the material examined herein. We would like to thank Clara F.
Rodrigues who participated in most of the cruises, often assisting with sample
collection and sorting, and also provided the map with the location of sampling sites,
and João Gil for his very useful comments and indispensable help with bibliography.
