G–I). Pre-epipodite setulated; epipodite oval, without projection. Exopodite of irregular shape with protrusion on inner side, with seven setae; seta 1 being longest; length of setae decreases evenly from seta 1 to seta 4; seta 4 about 2/3 length of seta 1; seta 5 and 6 about 1/2 length of seta 1; seta 7 about 1/3 length of seta 1. Setae 1–5 flat, plumose; seta 6 setulated unilaterally in basal part; seta 7 naked. Inner portion of limb IV with four setae: scraping seta (1) slender; three flaming-torch setae (2–4) long and slender, increasing in size basally; seta 4 almost 2 times shorter than seta 4, armed with 5–7 thick setules each. Small sensillum located near bases of setae 2–4. Four inner setae (a–d) slightly increasing in size basally. Gnathobase with one 2-segmented setae, a small hillock distally and a sensilla. Filter plate IV with six setae.

J) large, much bigger than in the previous species. Pre-epipodite setulated; epipodite oval, with very short projection. Exopodite very large, oval, with four plumose setae, their length evenly decreasing basally. Two small hillocks with long setules located on basal side of exopodite near seta 4. Inner lobe long, narrow, with setulated inner margin. At inner face, two setae of similar length: outer seta densely setulated in distal part; inner one with long thin setules unilaterally in basal part and thicker and longer setules in distal part. A small sensillum located between inner seta and filter plate. Filter plate V with four setae.
