Male: 6, P5.
Nota: The right P5 has a short endopod armed with 3 spines. From the 1st basipodal segment, the 2nd, and the 1st exopodal segment there are elongated linguiform projections; the one from the 1st exopodal segment exceeds in length the 2nd. The terminal hook is rather short and falciform. The left P5 has no endopod; the 1st exopodal segment has a long, slender spine at its outer distal angle; the 2nd segment is oval in outline and has a lateral spine at about 1/3 of its length.

Female: 7, P5.
Nota: Rostrum bifid, with long filaments.
Last thracic segment terminates in lateral spines.
Urosome 4-segmented; there are spines on the distal margins of the first three segments.
Caudal rami 7 or 8 times as long as broad.
A1 20-segmented, extending to the 2nd urosomal segment.
Exopod of A2 7-segmented.
In the P5, 1st exopodal segment elongated; 2nd segment (according to Cleve) terminates in 3 plumose setae, the central being about twice as long as the inner
