This crustacean is known from California, USA.
In adults, the propodus of the first walking leg is narrow, less than twice the width of its terminal claw.
It is known from brackish to fully freshwater habitats.
In adults, the inner branches of the fourth and fifth abdominal appendages lack gill folds.
In adults viewed from the side, the front edges of the side plates on thoracic segments two to four are not raised, so the plates do not appear S-shaped.
