Antenna 2 strongly pediform and well developed (clasping) in both sexes; peduncular segment 4 with strong bidentate posterodistal process; segment 5 short, usually with median tooth near mid-point. Gnathopod 1 subchelate. Gnathopod 2 propod slender, not longer than combined merus and carpus; dactyl short, typically tridentate. Urosome segments not coalsed. Uropods 1 and 2 medium, peduncles broadening distally; rami short, straight; inner and outer margins often spinose or setose, apex little out-curved. Uropod 3, ramus longer than peduncle, slightly broadened, setose apically. Telson short, broad, spinose hooks at hind comers and dorsally. Coxal gills medium broad, sac-like, on pereopods 3-6.
