| Popis: | A new oligotrich similar to Novistrombidium was discovered in plankton samples from an artificial tributary of the Salado River, Buenos Aires province, Argentina, in summer 2010. Propecingulum fistoleramalliei sp. n. has an obovate and anteriorly truncated body, with a conspicuous ventral furrow, is flattened ventrally, and has a prominent right apical protrusion. It temporarily attaches to the substratum by a posterior mucous thread. Rod-shaped extrusomes arranged equidistantly and insert directly above the girdle kinety. The macronucleus is globular to ellipsoidal. The contractile vacuole is located in the left, anterior quarter of the cell and the adoral zone is composed of 30–35 collar, 9–14 buccal, and two thigmotactic membranelles. The girdle kinety is dextrally spiraled and ventrally open; the ventral kinety is posterior to anterior end of the girdle kinety. The oral primordium develops posterior to the right thigmotactic membranelle and anterior the stripe of extrusomes above left, lateral portion of the girdle kinety. The SSUrDNA phylogeny confirms one more time that Novistrombidium is not monophyletic; consequently, we elevate the subgenus Propecingulum up to genus rank and redefine the genus Novistrombidium.
