Urosome 2-segmented, genital segment with a backwardly pointed spine above the genital opening and a dorsal swelling on the right side. Anal segment symmetrical, dorsally overlapping the furca. Exopodite stout and curved inwards, with 3 minute external marginal spines and 3 apical spines, the middle the longest. Endopodite bifurcated apically.

Male: Cephalosome resembles female. Lateral angles of the last metasome segment are asymmetrical, the left side produced into a pointed straight spine reaching the third urosome segment, the right side bluntly rounded, bearing a thin pointed curved process, longer than the spine on the left. Urosome 5-segmented, with spine on the dorsal right genital segment; right side of segment 3 with large protuberance with spinules on tip. The right leg with a claw, basis broad in middle and with 2 sub-equal seta.
