). Intercoxal sclerite (not shown) not transversely elongate, trapezoidal, with strong pointed process on distal outer corners, without surface ornamentation. Coxa with outer spinules proximally and medial minute spinules subdistally. Basis with strong acute inner process, with much smaller process between rami, with inner long and selender spinules, with outer seta. Exopod three-segmented, reaching slightly below middle of ENP3; first and third segments longest; EXP1 and EXP2 with outer acute distal process, with outer and distal spinules, and with distal inner frill as shown, distal processes of EXP3 as shown; EXP1 without, EXP2 with subdistal outer pore; EXP1 and EXP2 with one inner seta; EXP3 seemingly without spinular ornamentation, with two inner setae, two apical elements and three outer spines. Endopod three-segmented, longer than exopod; ENP1 shortest, about 0.7 times as long as ENP2; ENP2 and ENP3 subequal in length; all endopodal segments with longitudinal row of outer spinules; ENP1 and ENP2 with outer and inner acute distal processes, but outer process of ENP2 remarkably longer, both segments with apical minute spinules, distal processes of ENP3 as shown; ENP3 with subdistal medial pore; ENP1 with one, ENP2 with two inner setae; ENP3 with one inner seta, two apical elements and one outer spine.
