Longitudinal musculature of body wall not divided into longitudinal bands, instead forming solid layer. 2 retractors of introvert, both ventral and fastened into posterior third of trunk.

muscles well-developed. No rectal diverticulum found. 2 nephridia partially fastened to body wall by mesenterial filaments. Nephridia 80% as long as trunk region (Ref. 1815).
