Lower lip, lobes widely separated. Maxilla 1, inner plate strongly setose medially; outer plate with eleven robust setae, in simple 7 / 4 arrangement; palp two-articulate, article 2 large, expanded distally. Maxilla 2, inner plate with oblique row of mediofacial pappose setae. Maxilliped well developed, inner plate emarginate distally, palp four-articulate. Coxae 1 and 2 large, broad, subrectangular. Gnathopod 1 simple, propodus longer than carpus, dactylus shrouded in setae. Gnathopod 2 subchelate, propodus shorter than carpus. Pereopods 3 to 7 prehensile (on P 7 poorly developed). Pereopods 3 and 4 carpus longer than wide. Pereopod 5, basis suboval. Uropod 1 peduncle normal, rami variable. Telson with apices incised.
discussion
