Genital segment with 4 spines, 2 on the right side, subequal in lengths, another 2, very unequal in sizes, on the left side, the posterior one being much larger than the anterior oone. A1 16-segmented. P5 asymmetrical, exopods with the outer border of the right one with 3 denticles; the left exopod with the inner border smooth and the outer border bearing only 2 denticles, the distal one with 4 small denticles on its median side.; ebndopods all forked distally, the left one being larger than right one.

Nota: Genital segment with a denticle on the right side. 2nd and 3rd abdominal segments all roundly produced on the right side and densely covered with short spinules as in the preceeding segment. P5 asymmetrical; exopod 1 of rihht foot with a denticle and 2 setae on the upper half of the outer border, exopod 2 bearing a lateral, long and curved digitate process with its distal end enlaged, exopod 3 with 2 elevations of unequal sizes on the outer border and mounted each with a seta, and 2 setae at the distal half of the inner border; exopod 1 of the left foot about 3.5 times as long as broad, with a long seta at the outer distal angle, exopod 2 about one-half as long as exopod 1, bearing a group of fine setae on the inner as well as on the outer border, exopod 3 very small, bearing 2 distal setae.
