The objective of this study was to describe temporal variations in the diet and parasitological aspects in Liolaemus parvus. In order to examine the diet, we determined the volume, numerousness, and frequency of occurrence for each prey item and calculated the relative importance index. We removed nematodes from the stomach and estimated parasitic indicators. Liolaemus parvus presents an active searching mode. It is a predominantly insectivorous species with low intake of plant material and a specialist in feeding on prey items of the family Formicidae, although it also feeds on other arthropods like coleopterans, hemipterans, and spiders. We found temporal variations in its diet. The first record of Parapharyngodon riojensis nematodes is reported herein. Males showed higher nematode prevalence than females. We have expanded the number of host species and the distribution range of Parapharyngodon riojensis. The information provided about trophic ecology and parasitism is the first contribution to this lizard species? biology.
