Whole individual. Carapace length 1.9 cm. Notice how the 6th abdominal segment is twice as long or more than the 5th abdominal segment, and that it does not have a dorsal carina. Also note that abdominal segments 3, 4, and 5 have a posteromesial spine.
Dorsal (slight angle) view of the uropods and telson. The spiny endpiece on the telson has been slightly damaged but the long lateral spines at the base can still be seen. A few of the dorsolateral spines along the telson can also be seen along the top margin.
This side view of the head shows the long, toothed rostrum which extends out to near the end of the antennal scales (which are deflected downward out of view in this photo)
The three characteristic carinae which run nearly to the posterior end of the carapace can be seen in this side view. Dorsally there is a carina which runs from the rostrum (left) to near the posterior end of the carapace on the right. A small, sinuous carina runs from near the eye along the mid-side of the carapace. In this photo a number of bubbles are adhered to it. A sharp carina lines the ventral margin of the carapace. In this preserved specimen the ventral carina has retained much of its red color while the rest of the carapace has faded to yellow.
