| Diagnosis | Sipunculus phalloides phalloides: large worm, has 35-41 longitudinal muscle bands (LMBs) and do not subdivide in glans region. Unattached nephridia. Nephridiopores are open between 4 and 8 LMBs. Spindle muscle, weakly developed. Ventral retractors originate from 1 or 2 LMBs and extend over 2-6 bands while dorsal start on 12-16 LMBs and spread over 2-6 bands. Sipunculus phalloides inclusus/i>: There is more fusion or splitting of LMBs from anterior to posterior (Ref. 1840). |
