Exopodite rounded 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 about 1/3 length of seta 1; seta 6 about 1/2 length of seta 1; seta 7 shorter than seta 5. Setae 1–5 flat, plumose; setae 6–7 setulated unilaterally in basal part, setulae of seta 7 shorter than setulae of seta 6. Inner portion of limb IV with four setae. Scraping seta (1) slender; three flaming-torch setae (2–4) with length of distal portion and thickness of setulae increasing from seta 2 to seta 4; seta 2 with numerous thin setules; setae 3–4 with about 10 thick setules each; small sensilla located near base of seta 3. Four inner setae (a–d) increasing in length basally. Gnathobase with one 2–segmented setae, a small hillock distally, and two small sensillae. Filter plate with six setae.
