Abstract

A new genus and species of Tanaidacea are described from the manganese nodule province between the Clarion and the Clipperton Fracture Zone of the equatorial North Pacific Ocean collected during the French/German BIONOD expedition in 2012. The new genus, Cheliasetosatanais, can be diagnosed by the propodal and dactylus setation and the maxilliped endite armament. The male is also described and, while being a dimorphic swimming male, still shares the diagnostic characters and posseses a fully functional maxilliped.
