Tanystylum conirostre — Munilla & Soler-Membrives, 2014: 124–127, figs. 66–67. Type locality —off Bay of Naples. Material examined. Bissau-0810: BS191, 1♂; BS195, 1♂. Remarks. The morphology of our specimens is consistent with the original description given by Dohrn (1881), although, in our case, the distal spine in the lateral process is lacking. Habitat. This species has been collected from seaweed, hydrozoans and bryozoans (Munilla & Soler-Membrives 2014) from 0 to 45 m. Our specimens were collected between 25 and 29 m. Geographical distribution. This species is known from the North Atlantic Ocean and Mediterranean Sea (Dohrn 1881; Krapp et al. 2008). In the East Atlantic, it has been reported from Ireland (Bamber 2010) to south of Portugal (Esquete et al. 2016; Munilla & Soler-Membrives 2014) and from the Antilles and Gulf of Mexico in the West Atlantic (Child 1992b as Tanystylum orbiculare). Our specimens were collected from Guinea-Bissau, and these records considerably extend its area of distribution to the south in the East Atlantic.
