A new species of Aristias is described from the Aysén Region, southern Chile. The new taxon is similar to A. antarcticus Walker, 1906; however differs of all previous record of this species in Southern Ocean by a combination of characters: the anterior margin of lateral cephalic lobe is straight; the upper lip is bounded by a pit, not distinctly projecting in front of the epistome; the posterior margin of the epimeron 3 is smoothly crenulated; the inner ramus of uropod 3 is shorter than outer ramus, while the lobes of the telson are subtriangular. A complete description and illustrations of Aristias linnaei n. sp. are provided, and its relationship with similar species is discussed.
