This study provides data on the diet of two species of anteaters in Argentina. We worked with feces and the stomachs of road kill individuals. The feces were washed to separate the soil material consumed and 100 ml of the stomachs’ content were taken and examined. The differences in diet between both species of anteaters are related to their habits and the availability of ants. Ants consumed by
Pterygodermatites is a cosmopolitan genus of nematodes from mammals, and it is frequently encountered in 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 geographical distribution of Pterygodermatites ( Paucipectines) chaetophracti are provided. We examined 109 hosts belonging to Chaetophractus vellerosus, Chaetophractus villosus, Cabassous chacoensis, Dasypus hybridus, Tolypeutes matacus, and Zaedyus pichiy, from several regions of Argentina. Pterygodermatites ( Paucipectines) argentinensis can be distinguished from P. ( P.) chaetophracti by the morphology and size of esophageal teeth of both sexes, by subequal and longer spicules, by having only 1 precloacal cuticular semicircular fan in males, and by a greater number of cuticular processes in females. Cabassous chacoensis and Zaedyus pichiy are new hosts for Pterygodermatites ( P.) chaetophracti.
The southern three-banded armadillo Tolypeutes matacus (Desmarest, 1804) is distributed from eastern Bolivia, south-west Brazil, the Gran Chaco of Paraguay and Argentina, and lives in areas with dry vegetation. This armadillo is one of the most frequently consumed species by people in this area. The objective of this work was test for zoonotic species among helminths in 12 intestinal tracts of T. matacus in a locality from the Argentinean Chaco (Chamical, La Rioja province). The parasites were studied with conventional parasite morphology and morphometrics, and prevalence, mean intensity and mean abundance were calculated for each species encountered. In the small intestine, seven species of nematodes and two species of cestodes were identified. In the large intestine, two species of nematodes were recorded. We did not find zoonotic species but have added new host records. This study in the Chaco region thus contributes to growing knowledge of the parasite fauna associated with armadillo species in this region.
RESUMENTunga perforans es una pulga cuyas hembras perforan osteodermos de armadillos. Con el fin de incrementar nuestro conocimiento sobre la distribución de esta pulga en Argentina, se examinaron los armadillos depositados en diversas colecciones de mamíferos. Se tuvo en cuenta la presencia de lesiones similares a las producidas por T. perforans. Se hallaron en total 75 corazas con perforaciones atribuibles a esta especie en Chaetophractus vellerosus, Chaetophractus villosus, Tolypeutes matacus, Zaedyus pichiy, Euphractus sexcinctus y Priodontes maximus. Estos hallazgos sugieren que T. perforans está ampliamente distribuida en los armadillos presentes en zonas áridas y semiáridas de Argentina.
