A description is given of a corymorphid polyp, Corymorpha tomoensis Ikeda, 1910, collected during an expedition of the National Museum of Natural History, Leiden, The Netherlands, to the Indonesian island of Ambon. This is the first record of a polyp of the genus Corymorpha M. Sars, 1835 from Indonesian waters; corymorphid medusae were collected during the Siboga Expedition and described by Maas (1905) as Euphysora bigelowi; the polyp of that species was subsequently reared in the laboratory (Sassaman & Rees, 1978) and identified as a species of Corymorpha. Species now classified in Corymorpha M. Sars, 1835 are briefly reviewed and their status and distribution discussed.
