Diagnosis

( Cutler and Cutler 1985): Sipunculid with longitudinal muscle bands (LMBs) and the nephridiopores open between LMBs 4 and 5, 5 and 6, 6 and 7 or 7 and 8. Nephridia less than 25% of trunk length and unattached. They open 5-10% of the trunk length anterior to the anus. The ventral retractors originate on LMB 1 or 2 and extend over 2-6 bands, while the dorsal ones start on LMB 12-16 and spread over 2-6 bands. The LMBs do not subdivide in the glans region. Spindle muscle weakly developed (Fig. 7 f).
