Resumen:
Abstract Nematodes belonging to genus HedrurisNitzsch, 1821 (Nematoda: Hedruridae) were found inthe stomach of the freshwater fish Oligosarcus jenynsii(Gu¨nther, 1864) (Characidae) from a shalloweutrophic lake in Argentina. Morphological comparisonswith congeneric relatives showed that thesenematodes belong to a new species, for which H. bifidan. sp. is proposed. Hedruris bifida n. sp. can bedistinguished from its congeners by the followingcombination of characters: bifid deirids, absence ofprecloacal papillae and nine pairs of postcloacalpapillae and non-mammillated eggs. The new speciesclosely resembles Hedruris suttonae Brugni & Viozzi,2010¸ the only known species from Argentina; however,the bifid deirids in the new species and thedistribution pattern of perianal spines in femalesclearly distinguish both species. Hedruris bifida n.sp. represents the second nominal species of the genusin Argentina and the eighth species described in theNeotropical region.
