The genus Pristidactylus is restricted to southern South America (Lamborot and Diaz 1987. J. Herpetol. 21:29?37) and six species of this genus are recorded from Argentina. Pristidactylus scapulatus is endemic to Argentina, inhabits the eastern Andean slopes of San Juan, Mendoza and Neuquén Provinces (Abdala et al. 2012. Cuad. Herpetol. 26:215?248), and feeds on invertebrates (Cei 1993. Reptiles del Noroeste y Este de la Argentina Herpetofauna de las Selvas Subtropicales, Puna y Pampas. Museo Regionale di Scienze Naturali. Torino. 949 pp.), fruits (Acosta et al. 2004. Herpetol. Rev. 35:171?172), and occasionally other lizards (Villavicencio et al. 2009. Herpetol. Rev. 40:225?226; Sanabria and Quiroga 2009. Herpetol. Rev. 40:349?350; Victorica et al. 2018. Herpetol. Rev. 49:539). Two specimens of P. scapulatus (one male [96 mm SVL] and one female [97 mm SVL]) from Tocota (30.69136°S, 69.55403°W, 3214 m elev.), Iglesia Department, Provinces of San Juan, Argentina were collected (by noosing) in December 2017 and examined for helminths. Seventeen nematodes (female fourth-stage larvae) were isolated from the stomach and identified as Physaloptera sp. Infection prevalence was 50% with an intensity of 17. The nematodes were deposited in the Colección Helmintológica de la Fundación Miguel Lillo, San Miguel de Tucumán, Argentina (CH-N-FML #07754). In Argentina, Physaloptera spp. have been reported in the following reptiles, Liolaemus spp. (Ramallo and Díaz 1998. Bol. Chil. Parasitol. 53:19?22; O?Grady and Dearing 2006. Oecologia 150:355?361), Tropidurus etheridgei (Cruz et al. 1998. Herpetol. Nat. Hist. 6:23?21), Leiosaurus spp., (Goldberg et al. 2004. Comp. Parasitol. 71:208?214) and Xenodon merremi (Lamas et al. 2016. Facena 32:59?67). Physaloptera sp. in Pristidactylus scapulatus is a new host record from San Juan Province, Argentina.
