Tabachnick, K.R., Menshenina, L.L. 2013. New data on glass sponges (Porifera, Hexactinellida) of the northern Mid-Atlantic Ridge. Part 2. Aphrocallistidae, Euretidae, Euplectellidae and Rossellidae (with descriptions of two new species of Sympagella). Mar. Biol. Res. 9: 469–487.
Species of hexactinellid sponges (families Aphrocallistidae, Euretidae, Euplectellidae, and Rossellidae) collected on the ECOMAR expeditions of the RRS James Cook to the northern Mid-Atlantic Ridge are considered. Two species new to science of the genus Sympagella (Rossellidae, Lanuguinellinae) are described: S. cooki sp. nov. has as a unique feature the absence of discoidal and onychoidal outer ends in microscleres; Sympagella ecomari sp. nov. has the only types of microscleres represented by plumicomes and spicules with discoidal outer ends. A new name, Bathydorus levis pseudospinosus, is suggested for Bathydorus levis spinosus Wilson, 1904 (junior homonym) to avoid homonymy with Bathydorus spinosus Schulze, 1886 (senior homonym).
