Zygophylax levinseni ( Saemundsson, 1911)

Zygophylax levinseni: Ramil & Vervoort, 1992: 78–82 , figs. 18a–d, 19a–f; Calder & Vervoort, 1998: 35–37, fig. 17a–c; Schuchert, 2001: 71–72; Vervoort, 2006: 240–242, fig. 16.

Material examined. MAURIT-1011, stn MUDR20 , 16º08´11”N, 16º56´08”W, 405 m, 7-XII-2010: one fragment, without coppiniae .

Biology. This species was collected from bottoms of L. pertusa and M. oculata ( Altuna Prados & Álvarez Claudio 1994) and was found growing on a sponge, Acryptolaria longitheca ( Allman, 1877) ( Calder & Vervoort 1998) and a gorgonian axis ( Vervoort 2006). Coppiniae have been found only in December ( Ramil & Vervoort 1992).

Distribution. Zygophylax levinseni has a Northeast Atlantic distribution, from South of Iceland to south of Cape Verde Islands, including the Mid-Atlantic Ridge ( Schuchert 2001; Vervoort 2006). The records of the species were summarised by Vervoort (2006). In West Africa, it was collected from Morocco ( Ramil & Vervoort 1992), Mauritania ( Gil & Ramil 2017a) and Cape Verde Islands ( Vervoort 2006). Its bathymetric distribution is between 183 ( Altuna Prados & Álvarez Claudio 1994) and 3647 m ( Ramil & Vervoort 1992).

Our material was obtained from a depth of 405 m.

Remarks. Although our colony is only a fragment, it is consistent with the material described by Ramil & Vervoort (1992).
