Three metacestodes were collected from the mesentery and the surface of the liver of three adult alpacas (Vicugna pacos) in a slaughterhouse located in Puno, Peru. Various features of the metacestodes were observed for morphological identification. A molecular diagnosis was performed by PCR-based sequencing of mitochondrial genes of cytochrome c oxidase subunit 1 (cox1) and the NADH dehydrogenase subunit 1 (nad1). All metacestodes were identified as Taenia omissa by morphology and molecular methods The isolates from alpacas showed significant sequence similarity with previously reported isolates of T. omissa (95.7–98.1% in cox1 and 94.6–95.1% in nad1). Our report is the first to detect T. omissa metacestodes in alpacas and to reveal that alpacas are natural intermediate hosts for this parasite.
