A new genus Storthyngurella and three new species are described from deep–sea basins and trenches of the Southern Hemisphere. Storthyngurella is characterised by: long dorsal and lateral spines on the body; a terminal spine on the pleotelson; a long spine on the basal article of both antennae; narrow posterior pereopods 5–7; elongated distal lobes of male pleopod 1 extending far beyond the distal margins of pleopods 2; a long stylet of male pleopod 2, which is more than two–thirds as long as the protopod; and elongated uropods with tubular protopod and rami. The new genus is most similar to Storthyngura and Microprotus.
