- 2nd urosomite with serrate distal margin.
- 3rd urosomite bearing denticulate hyaline frill.
- Anal somite short, telescoped inside preceding somite.
- Caudal rami symmetrical, with row of setules along inner margin, 6 setae: seta I lacking, seta II cuneiform, seta V longest, seta VII located dorsally at distomedial angle of ramus.
