Carapace thin, weakly arched cylindroid, and elongated. Carapace surface covered with concentric muri and short muri, forming reticulation in anterior area. Concentric muri in antero-dorsal area showing like broken line. Inside valve, depressed triangular lamella of prismatic layer in anteroventral area and broad vestibules in anterior area in both male and female. Fourth and fifth podomeres of antennule fused. All terminal claws of thoracic legs bearing one small spinous process at 1/3 from proximal end. Male copulatory organ bearing sub-oval capsule and biramous distal lobe: one tip sharp and triangular, other one with round tip bent at almost right angle. Copulatory duct short and coiled.
