El conocimiento sobre endoparásitos en aves silvestres del género Rhea en Argentina es fragmentario e incompleto. En este sentido, el objetivo del trabajo fue determinar mediante análisis de fecas, la presencia de huevos de endoparásitos en Rhea tarapacensis Chubb, 1913 (Rheiformes: Rheidae) en una localidad de la precordillera central de Argentina. Los muestreos se realizaron en la Reserva Don Carmelo, Departamento de Ullum, Provincia de San Juan, en abril 2017. Se examinaron un total de 9 heces frescas de ejemplares adultos de R. tarapacensis. Se registró la presencia de huevos del género Heterakis sp. Este hallazgo parasitológico es el primero para esta especie en Argentina, contribuyendo al actual conocimiento parasitológico del género Rhea.

This study compiles records of endoparasites species in guanacos (Lama guanicoe) from Argentina. A bibliographic review of scientific works published between 1967 and 2017 was conducted. In addition, new unpublished records of localities within the province of San Juan were incorporated. The endoparasite fauna was represented by the phylum Nematoda, Platyhelminthes and Aplicomplexa, with a total of 65 total entries, 26 species mentioned and 14 others that were only identified at the genus level. The nematodes were the most numerous, followed by the Aplicomplexa and to a lesser extent the pylum Platyhelminthes. This work mentions for the first time the presence of nematodes such as Nematodirus sp, Trichuris sp, coccidia E. macusaniensis, E. ivitaensis and Eimeria sp in wild guanacos from the province of San Juan. There were few records in the environment with small populations of guanacos...
