Juvenile nectophore with dorso-lateral ridges of both sides close together alongside median groove, not extending to ventral side. Mature nectophores with broader median longitudinal groove; two dorso-lateral ridges placed very much to lateral edges of nectophore, continuing on ventral side as ventro-lateral ridges. On dorsal side two pairs of very short, frilled ridges extend into median groove as anterior and posterior ridges. Near ostium dorso-lateral ridges bifurcate surrounding ostium as inner and outer ridges. Dorso, and ventro-lateral ridges joined by short vertical ridge. Ostium directed ventrally.

Nectosac large, round, ostium broad, oval or quadrangular shaped. Musculature well developed; with four radial canals- simple, straight; lateral radial canals not forming loops but curve downward in mid region of nectosac on lateral surfaces before joining ring canal.
