Pterygodermatites is a cosmopolitan genus of nematodes from mammals, and it is frequently encounteredin the parasite fauna of armadillos (Mammalia, Xenarthra, Cingulata). In this work, a new species, Pterygodermatites(Paucipectines) argentinensis, is described, and new morphometric data, new host records, and the geographicaldistribution of Pterygodermatites (Paucipectines) chaetophracti are provided. We examined 109 hosts belonging toChaetophractus vellerosus, Chaetophractus villosus, Cabassous chacoensis, Dasypus hybridus, Tolypeutes matacus, andZaedyus pichiy, from several regions of Argentina. Pterygodermatites (Paucipectines) argentinensis can be distinguishedfrom P. (P.) chaetophracti by the morphology and size of esophageal teeth of both sexes, by subequal and longerspicules, by having only 1 precloacal cuticular semicircular fan in males, and by a greater number of cuticular processesin females. Cabassous chacoensis and Zaedyus pichiy are new hosts for Pterygodermatites (P.) chaetophracti
