A total of 158 species of the genus Liolaemus occur in Argentina (Abdala and Quinteros 2014. Cuad. Herpetol. 28:55?82). Liolaemus fitzgeraldi is distributed in Argentina and Chile (Acosta et al. 2017. Los Reptiles de San Juan. Editorial Brujas, Córdoba. 130 pp.). In Argentina, L. fitzgeraldi is distributed in San Juan and Mendoza provinces (Abdala et al. 2012. Cuad. Herpetol. 26:215?248). This small species is predominantly omnivorous and has a unimodal activity pattern (Acosta et al. 2017, op. cit.). According to the latest categorization of lizards of Argentina, it holds a status of insufficiently known (Abdala et al. 2012, op. cit.). The purpose of our note is to provide, for the first time, a record of Parapharyngodon sp. in L. fitzgeraldi. Fourteen specimens of L. fitzgeraldi (seven juveniles: mean SVL = 24.1 ± 0.6 mm, range: 23?25 mm; seven adults: mean SVL = 51.7 ± 4 mm, range: 45?56 mm) were collected (by noosing) in January 2015 from Los Azules, Calingasta Department, Provinces of San Juan, Argentina. For each specimen, the body cavity was opened with a mid-ventral incision, the digestive tract was removed, and its contents examined for helminthes using a dissecting microscope. The nematodes found were stored in 70% ethanol. Nematode observation and identification was done using the diaphanization by lactophenol technique. Seven nematodes (6 females, 1 male) were isolated from the stomachs and identified as Parapharyngodon sp. The specimens were deposited in the parasitological collection of the Department of Biology, National University of San Juan (UNSJPar253).
