Abstract

Galicia Bank is a large seamount situated c. 200 km off NW Iberia with a minimum depth of 600 m. It was recently included in Natura 2000, an EU-wide network of nature protection areas. We here present the first taxonomic descriptions of cheilostome bryozoans from this bank. The specimens were collected through the Spanish project INDEMARES (during BANGAL 0 811 cruise conducted in 2011) and during two previous campaigns, the French Seamount 1 in 1987 and the German Victor Hensen in 1997). Twenty-five species were found, including 12 that are new to science, while five species remain in open nomenclature. Three new cheilostome genera (Breoganipora, Galiciapora and Placidoporella) are described. A lectotype is designated for Setosella vulnerata (Busk), and Palmicellaria tenuis Calvet is transferred to the genus Porella [as Porella tenuis (Calvet) n. comb.]. Additionally, our study shows that 48–60% of the bryozoan species are endemic to Galicia Bank. The degree of endemism of the Cheilostomata is thus the highest among all orders present on this seamount.
