Redescription of Thouarella brucei Thomson and Ritchie, 1906 (Cnidaria: Octocorallia: Primnoidae) and description of two new Antarctic primnoid species Author Zapata-Guardiola, Rebeca Author López-González, Pablo J. text Zootaxa 2010 2616 48 68 journal article 10.5281/zenodo.197916 5d407501-96a0-44cd-8a9c-47734417e6f9 1175-5326 197916 Genus Digitogorgia Zapata-Guardiola and López-González, 2010 Diagnosis (modified from the original description, modifications in bold) . Primnoidae with bottlebrush colonies and simple branchlets. Polyps elongated, cylindrical, markedly curved upwards to the branch, and arranged in whorls. Accessory operculars eight in number, stick shaped, close to eight operculars. Marginal scales without thorn or keel, eight in number, folding over operculars. Opercular and marginal scales, with pointed digitations distally, attenuated in body scales. Body scales in eight complete longitudinal rows. Coenenchyme with two layers : outer layer of oval shaped scales, inner layer with irregular tuberculate sclerites. Remarks on diagnosis. During the study of Digitogorgia brochi sp. nov. we observed the presence of an additional inner layer of irregular tuberculate coenenchymal sclerites. Coenenchymal sclerites were described as a single layer of scales in the type species D. kuekenthali Zapata-Guardiola and López-González, 2010 . After a re-examination of the coenenchyme of the holotype ZIZMH C11740 and paratype USNM 1128575 (2 fragments as BEIM-CRO- 30 in Zapata-Guardiola and López-González, 2010b : 317) of D. kuekenthali , an inner layer of irregular tuberculate sclerites ( Figure 7 ) was also observed.
