Pleopods: normal; inner ramus slightly shorter than outer ramus, coupling basis of inner ramus with 56 specific stout two-pointed plumose setae along inner margin (6 setae on pleopod 1, 5 setae on pleopods 2 and 3). Uropod 1: peduncle 1.22 times as long as outer ramus; outer ramus the shorter, 0.91 times as long as inner ramus. Uropod 2: inner ramus 1.8 times as long as peduncle, outer ramus the shorter, 0.66 times as long as inner. Uropod 3: inner ramus 3 times as long as peduncle, with acute and non-spinose apex; outer ramus about 0.6 times as long as inner; outer ramus with a row of 56 small spine-shaped setae along lateral and medial margins each, with acute and non-spinose apex.
