Diagnosis. Rostrum triangular, about as long as or slightly longer than lateral projections of carapace. Eyestalk short, stout; cornea dilated, ocular scale pointed. Major cheliped stout, shorter than walking legs; carpus with 2 rows dorsal spines, strong spines along lateral, mesial borders; hand with 3 rows small spines not continuing to fixed finger but also with numerous spinules on dorsal surface, fingers; row of low spines on lateral margin. Minor cheliped with spines similar to major cheliped. Pereopods 2, 3 long, with spines along margins of carpus, propodus; dactyls longer than propodi, curved, with serrate dorsal margins, 2 shallow grooves, close-set ventral spines. Telson asymmetrical, left lobe longer than right, with notches on lateral margins, terminal margin concave, with teeth. Uropods asymmetrical. Carapace length to 27.7 mm.
