Centrorynchus nahuelhuapensis n. sp. is described from the intestine of Strix rufipes, the rufous-legged owl, in Patagonia, Argentina. This species is characterized by the presence of 31?33hook rows with 16?17 hooks per row, distributed as follows: 5 true hooks, 4 transitional hookswith 4 alate processes, more evident in the first three, 7?8 spiniform hooks, and three cementglands. It differs from most members of the genus by having a filiform body, the arrangementand size of the hooks, the number of cement glands, and egg size. Part of the SSU and LSUgenes were sequenced and compared to those in GenBank. Sequences are most similar to otherspecies of Centrorhynchus, supporting their placement within this genus. We present the firstmolecular study for a species of Centrorhynchus from South America. Additionally, it is thesecond species of the genus described in Argentina, and the first species of a terrestrialacanthocephalan from a bird in Patagonia
