Resumo: 	In samples of raw sewage collected from a sewage treatment plant in Rio de Janeiro (ETE-Penha), we found populations of two species, Deviata estevesi Paiva &amp;amp; Silva-Neto, 2005 and Deviata brasiliensis sp. nov. The organisms were studied in vivo under phase contrast microscopy, differential interference contrast (DIC), and after protargol-impregnation. The population of D. estevesi exhibited more extensive variation in cirral pattern than previously described. The interphasic organisms of new species D. brasiliensis sp. nov. are distinguishable from their congeners based on a series of morphometric features: cirral row R3 usually presents 1-3 cirri behind the right frontal cirrus, on average there are four macronuclear nodules, and, during morphogenesis of cell division, primordium V of the proter originates from the anterior region of cirral row R5 instead of row R6, as in the type species D. abbrevescens Eigner, 1995. In D. estevesi, the ventral cirral rows replicate by within-row primordia, which develop independently for the proter and for the opisthe, suggesting that it belongs to or is closely related to Parastrongylidium, hence the combination P. estevesi comb. nov. is established.
