Antenna 1 (fig. 6C): peduncle segments with few short setae (not longer than diameter of the segment where they implanted); primary flagellum with 25−26 segments; accessory flagellum with 5 segments. Antenna 2 (fig. 6D): peduncle segments bearing some groups of short setae on dorsal margin; setae on ventral margins almost as long as (some longer) diameter of segment where they implanted; primary flagellum with 10 segments; setation of flagellar segments weaker than that of male; calceoli absent. Gnathopod 1 (figs. 6A, B): basis with many long setae on both anterior and posterior margins; setae usually more than 2 times as long as diameter of basal segment; propodus ovate with 2 groups of setae on anterior margin, palm with 3 spines on posterior corner, dactylus with 1 seta on outer margin. Gnathopod 2 (figs. 6E, F): merus and carpus elongate, propodus subrectangular, medial palmar spine absent, bearing 5 spines on posterior corner and groups of setae on inner surface. Pereopods 3−4 (figs. 7A, B) similar to those of male in setation; pereopod 3 bearing longer setae on posterior margins of merus and carpus than those in males. Pereopods 5−7 (figs. 7C −E) similar to those of male in setation along anterior margins of ischium and merus segments; basal segment of pereopod 7 bearing 8−9 setae on inner surface. Epimeral plates 1−3 (figs. 6G −I) similar to those of male in setation. Uropods 1−2 (figs. 6J, K) seem like similar to that of males except presence of long setae on both margins of outer lobe of uropod 2. Uropod 3 (fig. 7F) and telson (fig. 6L) similar to that of male in setation. Oostegites broad, ovate, on pereopods 2 to 5.

In males, setation of flagellar segments of antenna 2 and gnathopod 2 are age dependent; larger specimens have more setose flagellar segment of antenna 2 and palm of gnathopod 2. Larger male specimens have more elevated process on their urosomites. Number of setae on inner surface of pereopod 7 can be increase by age.
