| Abstrakt: | A new tanaidacean, Tanaella quintanai sp. nov., is described based on specimens collected from depths of 1,598 to 2,853 m during 2014-2015. The new species appears to be most closely related to the western Atlantic species, T. kroyeri and T. mclellandi . Tanaella quintanai can be separated from the two former, as well as from the other members of the genus by a combination of characters, including (1) a labium with apical lobe bearing one blunt seta (2) a cheliped with the inner margin of the dactylus bearing a sub-proximal bipinnate seta, (3) pereopods 1-3 with basis having sub-dorsoproximal and sub-ventroproximal margins setulose, (4) pereopods 4-6 with basis having ventroproximal margin setulose, (5) pereopods 4-6 with unguis bearing two parallel rows of small setules, and (6) a pleotelson as long as pleonites 1-5 combined. A key separating the currently recognized species of Tanaella is presented. Competing Interests: Néstor E. Ardila is an employee of ECOMAR Consultoría Ambiental, Bogotá, Colombia.
