The anterior margin of this segment with five to eight teeth, the inner two largest; the outer margin has two (or one) large teeth. The pereiopods 2 to 5 are slender, without fringes of long hairs. On the anterior margin of the thoracic sternum the two anterolateral teeth form a deep sharply V-shaped median incision.
