Remarks.

A relatively large species, with a prominent, posteriorly acute keel on sternite 7 that extends posteriorly over pleopods in both the male and female specimen. The male has a short diffuse head band, and weak mottling on the tergite lateral margin of pereonites 2, 5 and 7, laterally on pereonite 7 and very lightly at anterolateral angles of the pleotelson. The female pleopod 2 differs from other species in having a distinct subterminal inflection to the lateral margins. The pseudorostrum is anteriorly concave. The male specimen lacks antenna.
