Endopod 2-segmented, 1st segment with 2 unequally long setae and row of spinules along distal margin, 2 nd segment bilobed, subterminal lobe with 9 setae, apical lobe with 6 setae. Exopod 8-segmented, segments 2-4 partially fused, with incomplete suture ; esgments 1-7 each armed with 1 seta, terminal segment with 4 apical setae.
- Labrum well developed, bordered by row of strong spinules arranged in tight pattern.
- Md with gnathal blade heavily sclerotized, with 4 strong medial teeth, dorsal teeth bicuspidate, large anterior tooth separated from main blade by wide diastema, tooth furnished with pair of strong secondary monocuspidate teeth (asterisks in fig.2 E). Palp biramous, basis with 4 subequal setae. Exopod relatively short, 5-segmented, setal formula 1, 1, 1, 1, 2 ; Endopod 2-segmented, 1st segment with 4 subequal setae, 2 nd segment with 11 setae.

- Ueosomewith 5 somites.
- Caudal rami symmetrical, about 2 times longer than wide, armed with 5 caudal setae ; inner margins of rami slightly setulated
- A1 18-segmented, extending to distal part of 2 ndurosomite (ancestral segments I-IV, V-VIII, and IX-X fused).
- A2 biramous, coxa and basis completely fused with simple seta ; endopod 2-segmented, 1st segment unarmed, 2 nd segment bilobed, ornamented with row of spinules on distal margina at insertion of apical setae. Subdistal lobe with 4 setae, 3 of them apical, 1 subapical ; distal lobe armed with 5 setae ; exopod incompletely fused, armed with 5 setae.
- Md coxal gnathobase absent, basis armed with short papilliform seta ; exopod 2-segmented, armed with 6 setae, with partial sutures (arrowed in fig.3, F ) ; endopod 2-segmented, 1st segment unarmed, 2 nd endopodal segment with 8 setae.
- Mxp reduced, 4-segmented, including long, robust syncoxa, shorter subrectangular basis plus 2-egmented endopod. Syncoxa naked, basis with short seta. 1st endopodal segment with 3 setae, outermost being thick, bipinnate ; 2 nd segment with 4 setae, 2 of them thick, bipinnate.
- P5 strongly asymmetrical ; right leg as in female, represented by rounded lobe ; left leg elongate, 5-segmented, almost as long as urosome. Penultimate segment with pointed process on distal margin ; distal segment with short spiniform process and long, slender apical spine.
