Abstract
In samples of activated sludge obtained from a wastewater treatment plant located in Rio de Janeiro State, Brazil, we discovered Parentocirrus brasiliensis sp. n., a new species of spirotrichous ciliate characterized as: Parentocirrus measuring about 110 x 75μm, body outline elliptical, with 2–3 buccal cirri and 3–5 posterior frontal cirri of the same size, and 2–4 postperistomial cirri. Nuclear apparatus composed of 4–6 macronuclear nodules and 1–6 micronuclei. Dorsal side shows 6 (rarely 5) kineties, with very few scattered kinetids between kineties 3 and 4. The new species differs from P. hortualis mainly in the configuration of dorsal kineties, the relative position of the posterior frontal cirri, the average number of macronuclear nodules, the number of postperistomial cirri, and the average body size.
