Erebusssau nom. nov. was originally described by Bussau, (1993) in his PhD thesis “Taxonomische und ökologische Untersuchungen an Nematoden des Peru-Beckens” but the name assigned was already in use, becoming an invalid name. Based on male specimens recovered from the Clarion-Clipperton Fracture Zone, we propose a new replacement nomen for the genus and describe a new species, also adding information about juveniles. Erebussau nom. nov. differs from all other Meyliidae genera by its peculiar offset head. Erebussau profundus sp. nov. differs from Erebussau tenebricosus nom. nov., comb. nov. by its larger size, the presence of pre- and post-cloacal supplements and the shape of the spicules. We also describe a new genus of the family Desmoscolecidae, Odetenema gesarae gen. nov., sp. nov. with an updated key to the genera of the subfamily Tricominae. Odetenema gen. nov. differs from the described Desmoscolecidae genera mainly in terms of the cuticle annulation pattern and the unique end ring with two tubular outlets. Erebussau tenebricosus, E. profundus sp. nov. and Odetenema gesarae gen. nov., sp. nov. have so far only been reported from deep-sea areas where polymetallic nodules are present.
