in having pereopods 5–7 with rectractile and hooded dactyls, but differs primarily in the morphology of the mouthparts. In particular the mandibles have a relatively massive palp and the incisor, although broad, is relatively narrower than for other lanceolids because the distal half of the mandibular body, above the insertion of the palp, is considerably more narrowed. Also, the left mandibles have a well developed lacinia mobilis that is about as wide as the incisor and the first maxillae have relatively narrow outer lobes and relatively smaller and shorter inner lobes that barely reach the base of the palp. These characters are unlike any other lanceolid, making it difficult to accept a close phylogenetic affinity with

It differs primarily in that the pereon is not dorso-ventrally broadened, the body (head, pereon, coxae & pleon) is highly sculptured, the third article of the mandibular palp is subequal in length to the first two articles combined, the inner lobes of the maxilliped are almost as long as the outer ones, pereopods 3 & 4 also have retractile dactyls, pereopods 3–5 have extremely broad articles and pereopods 3–7 do not have a spoon-shaped process for the retractile dactyls typical of other lanceolids.
