Pereiopod I ambulatory, shorter than pereiopod II. Pereiopod II with several sensory spines on ventral margin of propodus,carpus, merus and ischium. Pereiopods V to VII similar, but decreasing in size posteriorly, dactylilacking; propodi oar-like, with long plumose marginal setae, shorter thancarpus, merus very short, ischium and basis subequal in length.
