Description
Size: Length: female 0.70-1.20 mm; male 0.74-1.4 mm.

Female: The proportional lengths of the cephalothorax and abdomen are as 31 to 9; the abdomen being thus contained 3.44 times in the length of the anterior region of the body. The body is comparatively robust and the forehead is uniformly rounded, terminating below in a pair of long and delicate rostral spines. The head and 1st thoracic segment are incompletely fused, traces of the original line of separation being clearly visible across the dorsal surface. The posterior border of the thorax is slightly emarginated.
The 1st abdominal segment is armed with a row of small spinules that runs parallel to and close to the posterior margin, except on the ventral aspect. The genital aperture is somewhat angular.The 1st antenna reaches back to the 2nd abdominal segment. Segment 12 bears a short oblique row of minute spinules and segments 13 to 23 inclusive each bear a longitudinal row of spinules along the proximal half of the segment.
Cephalosome fused with the first pedigerous segment. Urosome around a third the length of the prosome, genital and anal segments about the same length.

Male: The proportional lengths of the cephalothorax and abdomen are as 28 to 11, the abdomen thus being contained 2.55 times in the anterior region of the body. The dorsal profile shows a uniform curve and there is present in the mid-dorsal line the same small transparent swelling. The 4th and 5th thoracic segments are fused but the line of fusion can clearly be seen in the lateral region. The posterior thoracic margin is somewhat sharply rounded. The abdomen consists of five segments. In the 2nd, 3rd and 4th swimming legs, the margin of the distal portion of the last segment, as well as the margin of the 2nd segment, of the exopod are fringed with small spines.
