Diagnosis Freshwater Olindiidae medusae with closed ecto-endodermal statocysts in the velum which form centripetal tubes; bell marhin with well developed marginal cnidocyst ring, no gastric peduncle; 4 simple radial canals; no centripetal canals; gonadsonly on radial canals, hanging, pouch-like; evenly distributed marginal tentacles all of one kind, no adhesion organs.
Hydroid in fresh-water, solitary or forming small reptant colonies of 2 to 4, rarely 7 polyps; hydranths without tentacles, cylindrical, with apical mouth (hypostome) surrounded by cnidocysts forming a spherical capitulum under which the polyp is slightly tapering, forming a distinct neck; basal portion of hydranths with periderm covering, attaching colony to substrate; medusa buds lateral, on the middle or lower part of body column; asexual reproduction by frustules, transversal division and resting stages (cysts).
