Raillietiella gigliolii is a Neotropical pentastomid parasite found in Amphisbaena alba. Collections were made in northeastern Brazil in a remnant area of Atlantic Forest (07 masculine 10' S and 35 masculine 05' W) in the municipality of Cruz do Espírito Santo, Paraíba State, and in a Humid Forest area (07 masculine 16' S and 39 masculine 26' W) on the slopes of the Chapada do Araripe Mountains, municipality of Crato, Ceará state, Brazil. Nine specimens of A. alba and 12 of A. vermicularis were collected to gather basic ecological data (prevalence and mean intensity of infection) concerning these parasites. Raillietiella gigliolii was found infecting the lungs of both species. The prevalence for A. alba was 55.5% (5/9), with a mean intensity of infection of 5.0 +/- 2.53 and amplitudes of 1-13. A. vermicularis demonstrated prevalence of 50%, with a mean intensity of infection of 5.3 +/- 2.1 and amplitudes of 1-14. This represents the first record of R. gigliolii as a parasite of A. vermicularis. Our results suggest that R. gigliolii is a generalist parasite species and that an overlapping diet is the determinant factor in the sharing of its final hosts.
吉利奥氏瑞立绦虫是一种新热带区的五口吸虫寄生虫，寄生于白蚓蜥体内。采集工作在巴西东北部进行，地点位于帕拉伊巴州埃斯皮里图圣克鲁斯市大西洋森林的一片残留区域（南纬07°10′，西经35°05′），以及巴西塞阿拉州克拉图市阿拉里皮山山坡的一片湿润森林区域（南纬07°16′，西经39°26′）。采集了9只白蚓蜥标本和12只蠕蚓蜥标本，以收集有关这些寄生虫的基本生态数据（感染率和平均感染强度）。发现吉利奥氏瑞立绦虫感染了这两个物种的肺部。白蚓蜥的感染率为55.5%（5/9），平均感染强度为5.0±2.53，感染幅度为1 - 13。蠕蚓蜥的感染率为50%，平均感染强度为5.3±2.1，感染幅度为1 - 14。这是吉利奥氏瑞立绦虫作为蠕蚓蜥寄生虫的首次记录。我们的结果表明，吉利奥氏瑞立绦虫是一种泛寄生物种，重叠的食物来源是其终末宿主共享的决定性因素。
