Soil samples were taken from a temporary pond located in Buenos Aires province,Argentina, during the dry phase in the summer of 2005. The ciliates were studied alive and after staining with protargol. Deviata rositae n. sp. measures 112--154 Am in length and 21--28 Am inwidth in vivo and has a vermiform body. The contractile vacuole is located in the mid-body on the left. The macronucleus is moniliform and there are 1--3 micronuclei. The oral apparatus is composed of 14--18 adoral membranelles and straight paroral and endoral membranes that never intersect each other. The somatic ciliature is arranged in 4 frontal cirri, 1 buccal cirrus, 6 long and slightly spiraled rows of cirri with the first right row extending up to the equatorial or subequatorial region, and 2 dorsal rows of dikinetids. This new species of Deviata primarily differs from its congeners by the number of macronuclear nodules and the number and disposition of the dorsal rows of dikinetids.
