Diagnosis. Exoskeleton thin, minutely pitted. Rostrum about as long as blade of scaphocerite, with 10–14 dorsal, 4–8 ventral teeth, apex acute; may be raised into convex crest posterior to orbit. Carapace with weak suborbital, moderate antennal, strong branchiostegal teeth, latter with supporting carina; gastro-orbital, submarginal carinae. Eyes pigmented. Stylocerite slightly longer than eye. Scaphocerite with lateral tooth longer than blade. Third maxilliped longer than first or second pereopod, setose.
