Coralliidae (Anthozoa: Octocorallia) from the INDEMARES 2010 expedition to north and northwest Spain (northeast Atlantic), with delimitation of a new species using both morphological and molecular approaches

Three species of deep-water bathyal Coralliidae were collected during the INDEMARES 2010 expedition of the Spanish Institute of Oceanography to the Avilés Canyon System and the Galicia Bank (Spain, northeast Atlantic): Corallium occultum n. sp., Corallium cf. bayeri Simpson & Watling, 2011, and...

Description
Summary:Three species of deep-water bathyal Coralliidae were collected during the INDEMARES 2010 expedition of the Spanish Institute of Oceanography to the Avilés Canyon System and the Galicia Bank (Spain, northeast Atlantic): Corallium occultum n. sp., Corallium cf. bayeri Simpson & Watling, 2011, and Corallium niobe Bayer, 1964. The new species is supported by both morphological and molecular evidence, and its phylogenetic relationship within the Coralliidae is inferred. Corallium cf. bayeri is first recorded from European waters. Corallium johnsoni Gray, 1860 from off Portugal and Madeira, and Corallium tricolor (Johnson, 1898) from Madeira are redescribed from museum material, and their sclerites first depicted by scanning electron microscopy. The sclerome of C. johnsoni is more complex than previously thought, with occurrence of double clubs, and 6-, 7- and 8-radiates. A key is proposed for the identification of all the Atlantic species of the genus Corallium.
