- Anal somite wider than long, asymmetrical, right side longer than left.
- Caudal rami very asymmetrical, right ramus being longer and broader, inner margin of each ramus fringede with fine hairs; each ramus with 5 long plumose and 1 small setae.
- A1 22-segmented, symmetrical; posterior margin of segments 2-13 fringed with fine hairs.
