The strombidiid ciliate Novistrombidium rufinoi sp. nov. is described from observations on live and protargol-impregnated specimens. The organisms were isolated from samples of slightly brackish water from Cabiúnas Lagoon, located in Parque Nacional da Restinga de Jurubatiba, an environment conservation area in the northern region of the state of Rio de Janeiro, Brazil. The new species measures ~40 x 35 μm in vivo and differs from congeners by having a 7?11 μm long, adherent, non-retractile tail that lacks cilia and a conspicuously spring-shaped adoral zone which has two thigmotactic membranelles. Stomatogenesis in the opisthe is hypoapokinetal and parental oral apparatus is retained in the proter.
