Nota: Endopod of P1 1-segmented; exopod 3-segmented, each segment bears 1 external spine. Left P5 exceeddingly long with 5 segments; the first 3 segments (i.e, the 2 basal and 1st exopodal) are roughly of equal length, although the 1st basal is slightly longer than the others, the 4th segment is about 1/3 as long as the preceding segment and the 5th segment is short and somewhat claw-shaped with a pad covered with fine setae, the total length of the leg is about 1.75 times that the urosome; the right leg is short, reaching about to the end of the 1st basal segment of the left leg, and consists of 2 broadened basal segments and 3 exopodal segments, which may be partly fused.
