This species has been found growing on a polychaete tube (Ramil & Vervoort 1992). Fertile material has been collected in June (Allman 1877; Fraser 1944; Ramil & Vervoort 1992). The colonies studied by us were collected from different substrata, such as sponges, hydroids, the corals M. oculata and L. pertusa and the bivalve A. excavata . Gonothecae were recorded for the first time in December. Distribution. Plumularia filicula is an amphi-Atlantic species reported from the Ibero-Moroccan Gulf in the East and the coast of USA in the West Atlantic; records in the Pacific Ocean are considered dubious and need further confirmation (Ansín Agís et al . 2014). In West Africa, it was collected from Morocco (Ramil & Vervoort 1992) and Mauritania (Gil & Ramil 2017a). Its bathymetric distribution extends from 146 to 1318 m (Ramil & Vervoort 1992). Our material was collected from depths of 405 and 640 m. Remarks. Disposition of the hydrocladia in the same plane, the first ahydrothecate internode with one nematotheca, long internodes and morphology of the gonothecae allowed us identify these colonies as P. filicula (see Ramil & Vervoort 1992). : Published as part of Gil, Marta, Ramil, Fran & Agís, José Ansín, 2020, Hydroids (Cnidaria, Hydrozoa) from Mauritanian Coral Mounds, pp. 412-466 in Zootaxa 4878 (3) on pages 452-454, DOI: 10.11646/zootaxa.4878.3.2, http://zenodo.org/record/4425132 : {"references": ["Allman, G.
