Material examined. Stn. 3: 01.04.2008 —a few hydrothecae and nematothecae, but no gonothecae, on stolons of sertulariid and corynid hydroids. Stn. 6: 23.03.2008 —a small, sterile colony, on Halimeda sp.
Type locality. Near Solomon Islands, Melanesia (medusa).
Remarks. The present material is tentatively assigned to Kramp’s ( 1959 b) species. Since Cirrholovenia tetranema is reliably identified through its medusa stage, it is possible that similar polyps may produce different medusae.
Migotto & Cabral ( 2005) showed that Lafoeina amirantensis ( Millard & Bouillon 1973) is the hydroid of the medusa Cirrholovenia tetranema Kramp, 1959 and provided a complete redescription of both stages.
Distribution. Scattered records from both the western and eastern Atlantic, Mediterranean Sea, Indian and Pacific Oceans. A detailed list of records is provided by Migotto & Cabral ( 2005).
