Description
Size (female): length 3.093 mm; (male): length 2.674 mm

Female: The proportional lengths of the cephalothorax and abdomen are as 25 to 8, so that the abdomen is contained 3.125 times in the length of the anterior region of the body. The abdomen consists of two segments with the furca. The 1st antenna consists of twenty-two free segments . In the 5th pair of legs, the three external marginal spines on the exopod are serrated. The tip of the endopod appears to terminate in a single point. There is a small spine at the point of origin of the seta on the 2nd basal segment.

Male: The proportional lengths of the cephalothorax and abdomen are as 47 to 16, so that the abdomen is contained 2.938 times in the length of the anterior region of the body. The abdomen consists of five segments with the furcal rami. The 1st antenna reaches back to about the level of the posterior margin of the 3rd thoracic segment. The left antenna is unmodified but the segmentation is not quite the same as in the female. There are only seventeen free joints in the whole appendage, whereas in the female there are twenty-two. The cause of the difference is the greater degree of fusion met with in the proximal segments. Segments 2 to 8 are completely fused, segments 9 and 10 are fused and segments 11 and 12 are partially fused.
