Helminthological studies may contribute with valuable information on host biology and conservation. Herein, we provide new data on helminths infecting the lizard Norops fuscoauratus, testing one of the factors considered most important in parasitic ecology: host size. We analysed 25 specimens of N. fuscoauratus from three highland marshes in the Brazilian semi-arid. Eight taxa of helminths belonging to Nematoda, Trematoda and Acanthocephala were found. Physaloptera sp. showed the higher prevalence (40%), with a mean intensity of infection of 3.3 ± 1.46 (1-16) and mean abundance 1.32 ± 0.65 (0-16). Norops fuscoauratus represents four new host records for the helminths Cyrtosomum sp., Pharyngodon travassosi, Strongyloides sp. and Centrorhynchus sp. There is no relationship of host body size (P = 0.79) and mass (P = 0.50) with parasite richness. In addition, the present study contributes to the knowledge of the parasitic fauna of N. fuscoauratus and the Neotropical region.
寄生虫学研究可以为宿主生物学和保护提供有价值的信息。在此，我们提供了感染蜥蜴 Norops fuscoauratus 的寄生虫的新数据，检验了寄生虫生态学中最重要的因素之一：宿主大小。我们分析了来自巴西半干旱地区三个高地沼泽的 25 个 N. fuscoauratus 标本。发现了属于线虫、吸虫和棘头虫的 8 种寄生虫。Physaloptera sp. 表现出最高的流行率（40%），感染强度的平均值为 3.3 ± 1.46（1-16），丰度平均值为 1.32 ± 0.65（0-16）。Norops fuscoauratus 为 Cyrtosomum sp.、Pharyngodon travassosi、Strongyloides sp. 和 Centrorhynchus sp. 这四种寄生虫提供了四个新的宿主记录。宿主身体大小（P = 0.79）和质量（P = 0.50）与寄生虫丰富度之间没有关系。此外，本研究有助于了解 N. fuscoauratus 和新热带地区的寄生虫区系。
