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.

巴西半干旱高地沼泽中与 Norops fuscoauratus (Squamata, Dactyloidae) 相关的蠕虫

蠕虫学研究可能有助于提供有关宿主生物学和保护的宝贵信息。在此，我们提供了有关感染蜥蜴的蠕虫的新数据蝾螈，测试寄生生态学中被认为最重要的因素之一：宿主大小。我们分析了 25 个样本N. fuscoauratus来自巴西半干旱地区的三个高地沼泽。共发现八种蠕虫类群，分别属于线虫纲、吸虫纲和棘头虫纲。有翅目sp。显示较高的患病率（40%），平均感染强度为 3.3 ± 1.46（1-16），平均丰度为 1.32 ± 0.65（0-16）。蝾螈代表蠕虫的四个新宿主记录鱼腥藻sp.,鲢鱼,类圆线虫sp。和尖嘴龙sp。与宿主体型没有关系（磷= 0.79) 和质量 (磷= 0.50) 具有丰富的寄生虫。此外，本研究有助于了解寄生动物群。N. fuscoauratus和新热带地区。
