Description
Size (female): length 5.87 mm; (male): 5.349 mm.

Female: Color: The coloration of this species is striking; the general coloration of the body is a deep blue and on thoracic segments 1 to 3 in the mid-dorsal line is a deep blue spot surrounded by a halo of opaque silvery white; the terminal 5 or 6 segments of the 1st antenna are chocolate brown. There are also some scattered white spots on the dorsal aspect of the swollen abdominal segment. The proportional lengths of the cephalothorax and abdomen are as 20 to 7, so that the abdomen is contained 2.857 times in the length of the anterior region. The head is furnished with side hooks. The rostrum is bifid, terminating in a pair of stout spines; a well-developed rostral lens is present. The cephalon and 1st thoracic segments are fused; thoracic segments 4 and 5 are separate and the posterior thoracic margin is produced backwards on each side in a stout spine. The 1st antenna consists of twenty-four free joints, segment 8 and 9, 11 and 12 and 24 and 25 being, respectively, fused together, as is usual in this genus. The proximal thirteen segments bear a fringe of hairs on their posterior margin and the 14th segment carries a stout process. The 2nd antenna is of the usual type, but the exopod is considerably shorter than in some of the other members of the genus. The mouth-parts and swimming legs have the usual structure.

Male: The proportional lengths of the cephalothorax and abdomen are as 16 to 7, so that the abdomen is contained 2.286 times in the length of the anterior region of the body. The cephalothorax resembles that of the female.
The abdomen consists of five segments with the furcal rami. The right 1st antenna is modified to form a grasping organ; the left antenna is unmodified and resembles that of the female. The left antenna consists of twenty-two free segments; segments 8 and 9, and 11 and 12 respectively being fused either completely or partially.
