Antenna 2 with brush setae. Mandible molar setose with vestigial triturating surface. Maxilla 1 outer plate a well developed 7/4 crown. Maxilla 2 inner plate significantly shorter than outer plate. Gnathopod 1 weakly subchelate; coxa 1 large, about as long as coxa 2, subrectangular with straight anterior margin; ischium short (length less than 2 × breadth); carpus long (length 2 to 4 × breadth); propodus margins tapering distally.
