MARINE HETEROTROPHIC AMEBAS, FLAGELLATES AND HELIOZOA FROM BELIZE (CENTRAL-AMERICA) AND TENERIFE (CANARY-ISLANDS), WITH DESCRIPTIONS OF NEW SPECIES, LUFFISPHAERA-BULBOCHAETE N-SP, L-LONGIHASTIS N-SP, L-TURRIFORMIS N-SP AND PAULINELLA-INTERMEDIA N-SP

Thirty four taxa of heterotrophic protists (amoebae, flagellates and heliozoa) were encountered in cultures established from marine samples from Belize (Central America) and Tenerife (Canary Islands). Most species are flagellates drawn from the choanoflagellates, the cryptophyceans, the euglenids, the kinetoplastids, the bicosoecids, the chromulinids, the pedinellids and a variety of taxa of uncertain affinities (Protista incertae sedis). The identity of the thecate choanoflagellates Salpingoeca ringens Kent, 1880, and S. tuba Kent, 1880, is discussed, and four new species of heterotrophic protists are described: one new species of the amoeba genus Paulinella (Paulinella intermedia n. sp.) and three new species of the incertae sedis genus Luffisphaera Belcher & Swale, 1975 (Luffisphaera bulbochaete n. sp.; L. longihastis n. sp.; L. turriformis n. sp.).
