Description
Size (female): length 0.69 mm
The proportional lengths of the cephalothorax and abdomen are as 55 to 18, the abdomen being thus contained only 3.06 times in the length of the anterior region of the body, instead of 3.27 times as in the larger form.
Ist antenna reaches beyond the tip of the furcal ramus by about the last segment. The various segments carry rows of small needle-like spinules. The rows on the proximal segments running transversely and the distal ones longitudinally. The last two segments are devoid of spines. Leaf-like spines that are present on the posterior aspect of the 2nd segment of the exopod of the 4th leg.
