Urosome. Urosomite 1 (Fig. 10e): longest, with low boss close to the posterior margin; urosomite 3 longer than 2, with short, acute mid-dorsal projection. Uropod 1: peduncle elongate, lateral margin with robust setae, mesial margin setose; inner ramus, [broken], both margins setose; outer ramus 0.7

Uropod 2 (Fig. 10d): peduncle not tapering, both margins with short setae; [rami damaged], inner ramus, both margins setose; outer ramus, lateral margin setose. Uropod 3 (Fig. 10c): peduncle short, about as long as telson, with ventral subacute projection; outer ramus just longer than inner ramus. Telson (Fig. 10f) tapered, notched 40%.

It may be that this process has been present and is worn down in the holotype. Antenna 1 of the female (Fig. 6b) has a longer and more slender peduncle and fewer and more elongate flagellum articles compared to the male.</paragraph>
