The Leucothoidea are a group of marine amphipods with the posterior pereopods uniform and telson lobes fused (Bousfield 1983).

Characters (from Bousfield 1983): Gnathopods 1 and 2 strongly dimorphic, amplexing in male; antenna with neither calceoli nor brush setae; labium with inner lobes partially developed; left mandible with lacinia 5-dentate; pereopods 5–7 homopodous, equal, with coxae posterolobate; pereopod 7 gill absent; uropods 1 and 2 with rami lanceolate, bare, uropod 3 rami non-foliaceous; telson lobes totally fused; brood plate broad, setose.
