Abdomen 3-segmented.
The abdominal segments and furca are in the proportional lengths as 55:12:13:20 = 100.
A1 25-segmented, exceeds the end of the furca by distal 8 segments.
Md: exopod as long as endopod; exopod with 5 marginal setae; cutting edge with 4 teeth, the anterior very strong.
Mx1: outer lobe with 3 long setae; exopod with 7 setae of which the terminal 2 are very long; 2nd basal segment with 3 setae; 3rd inner lobe with 1 seta; 1st inner lobe with 7 spines; endopod and 2nd inner lobe absent.
Mx2 slender with on the lobes 1 to 6 and endopod: 3setae and a small spine on the 1st lobe, 2 setae on the 2nd, 2 setae on the 3rd; 3 setae on the 4th; 2 setae on the 5th; 1 seta on the 6th; 7 setae on the endopod.
Mxp: 1st basal segment as long as the 2nd; the 2nd basal segment has a row of hair-like spines on the anterior margin.
P5 3-segmented exopod and endopod; the inner marginal spine of the 2nd exopodal segment short, extends a little beyond the base of the inner marginal seta of the 3rd exopodal segment.

Rostrum consisting of 2 slender filaments.
Genital segment as long as the rest of urosome.
Caudal ramus as long as anal segment.
Mandibular palp biramous, exopod carrying 4 setae and shorter than endopod.
Mx1 with 1 seta on 3rd inner lobe; 3 setae on basis; 7 setae on exopod; 6 setae on outer lobe; 2nd inner lobe and endopod missing.
Both rami of P5 3-segmented; 1st and 2nd exopodal segments without external spines.
