[Cnidaria A hydromedusa of the subclass Leptothecata. Formerly its medusae and hydroids were classified separately, as the Leptomedusae and Thecata. When medusae, or hydroids, are alone being discussed, the words leptomedusa(n) and thecate are useful; but neither should be used as a formal taxon. See also thecate; anthomedusa.
