Th5 ending with a small point. Rostrum short, like blunt plate. A1 24-segmented, reaching the end of cephalothorax. Ri and Re A2 of the same length. Coxopodite A2, basipodite and Re1 A2 with 1 seta each, Re2 A2 with 2 setae, Ri1 A2 with 1, external lobe of Ri2 A2 with 7 long terminal and 1 shorter posterior seta, internal lobe with 7 (4 long and 3 short setae). Md palp base and Ri1 Md without seta, Ri2 Md with 5 setae. Mx1 gnathobase with 12 setae, second internal lobe with 5, third with 2 setae, protopodite near Ri base with 4 setae, Ri and Re with 11 setae each, external lobe with 8 setae. Mx2 with claw-like spine on fifth and fourth endites. First to fourth endites with spinules on surface near proximal border of lobes. Mxp robust with groups of 2, 3 and 3 setae (looking from proximal to distal end of the segment). P1-P4 with segmentation typical of the family. Re P1 with external spines on each segment; Ri P1 with well developed external lobe covered with hairs, basipodite with small spine in external distal corner of segment.
