Length: 30mm. Head with few small tubercles dorsally; pereonites 1-7 with small tubercles on dorsal and lateral surfaces. Antenna 1 about as long as ½ body length; antenna 2 about as long as antenna 1 peduncle segments 1 + 2. Gnathopod 2 attached to posterior end of pereonite 2; basis and propodus with small tubercles; propodus palm with proximal grasping spine, distal long projection separated from a seoncd long projection by a deep notch; most distal surface of propodus an almost square process (knuckle-like). Pereopods 5 - 7 propodus with graspins spines and setose palms. Gills elongate.

Caprellid, "Ghost" or "Skeleton" shrimps, so called for their skeletal appearance. Amphipod crustaceans, easily distinguished by the elongate stick-like body form and reduction of the abdominal appendages. Head is generally fused with pereonite 1. Pereopods on first 2 segments (pereonites) are most flexible and called gnathopods; gnathopods 2 being the largest, used in defense, feeding and substrate attachment. In many species pereopods 3 and 4 may also be reduced or absent. Gills on pereonites 3 + 4, rarely on pereonite 2. Pereopods 5 - 7 much smaller than 1 + 2, used for clinging to the substratum. In females, brood plates (öostegites) develop on pereonites 3 + 4. Much remains to be learnt about their biology, ecology and in many cases changing distributions.
