Leptodactylus syphax is distributed in central, southeastern and northeastern Brazil, eastern Bolivia and southern Paraguay, occupying open areas and rock outcrops, in rock cavities and termite burrows. We collected 21 frogs from the Caatinga region of the state of Ceará, northeastern Brazil, and 7,021 helminths were recovered from 18 of these hosts (overall prevalence = 85.7%). Six helminth taxa were recovered, as follows: Aplectana membranosa (n = 3,756); Schrankiana formosula (n = 3,176); larvae of Physaloptera sp. (n = 43); unidentified nematode larvae (n = 7); digenean metacercariae of Lophosicyadiplostomum sp. (n = 2); and cystacanths of Acanthocephala (n = 37). The similarity of helminth composition between L. syphax from the Caatinga and other species of the L. fuscus group showed that some anurans were clustered according to parasite species and others according to geographic locality. This study presents new helminth records for the Neotropical region, thus helping in understanding the pattern of species distribution, and it increases the knowledge of parasites associated with amphibians.
西法克斯细趾蟾分布于巴西中部、东南部和东北部，玻利维亚东部以及巴拉圭南部，栖息于开阔地区、岩石露头、岩洞和白蚁洞穴中。我们从巴西东北部塞阿拉州的卡廷加地区采集了21只青蛙，从其中18只宿主身上共采集到7021条蠕虫（总体感染率为85.7%）。共发现了6个蠕虫类群，分别如下：膜状阿普勒克线虫（n = 3756）；美丽施兰克线虫（n = 3176）；泡翼线虫属幼虫（n = 43）；未鉴定的线虫幼虫（n = 7）；洛福西双盘吸虫的复殖亚纲后尾蚴（n = 2）；棘头虫的棘头体（n = 37）。来自卡廷加地区的西法克斯细趾蟾与深色细趾蟾群其他物种之间蠕虫组成的相似性表明，一些无尾目动物是根据寄生虫种类聚类的，而另一些则是根据地理位置聚类的。本研究提供了新热带地区新的蠕虫记录，有助于了解物种分布模式，并增加了与两栖动物相关的寄生虫知识。
