An unusual new species of plexaurid octocoral, Alaskagorgia splendicitrina, is described from a specimen collected in the far west Aleutian Island Archipelago, Alaska, USA. Unusual features that separate it from its only congener include: the vibrant yellow color of the live colony and an arborescent growth form with numerous coiling and twisting branches, the pale yellow color of the sclerites and the lack of small and densely warted double-headed sclerites. The new species is represented by only a single specimen despite extensive sampling in the region during the past several decades; the speculation is that it radiated from the much less explored region to the west.
