Between February and August, 2012, thirty specimens of Atlantic moonfish, Selene setapinnis, were purchased in local markets in Niterói, State of Rio de Janeiro, Brazil, with the aim of analyzing the presence of anisakid nematodes, establishing their rates of parasitism and infection sites, due to importance in the sanitary inspection. A total of sixty nematode larvae, belonging to at least two species were found: nine larvae of Terranova sp., Anisakidae, with prevalence (P) of 13.3%, mean intensity (MI) of 2.25, mean abundance (MA) of 0.30 and range of infection intensity (RI) from 1 to 6; and 51 larvae of Hysterothylacium fortalezae, Raphidascarididae, with P = 26.7%, MI = 6.40, MA = 1.70, and RI = 1-17. The infection sites for Terranova sp. were the mesentery and liver serosa; and for H. fortalezae, the infection sites were the mesentery, abdominal cavity and liver serosa. New morphological data from scanning electron microscopy, on the external structures of H. fortalezae (mainly at the posterior end), are presented. This is the first report of H. fortalezae parasitizing S. setapinnis.
2012年2月至8月期间，在巴西里约热内卢州尼泰罗伊的当地市场购买了30条大西洋月鱼（Selene setapinnis）标本，目的是分析异尖线虫的存在情况，确定其寄生率和感染部位，因为这在卫生检查中具有重要意义。共发现了至少属于两个物种的60条线虫幼虫：9条异尖科异尖线虫属（Terranova sp.）的幼虫，感染率（P）为13.3%，平均强度（MI）为2.25，平均丰度（MA）为0.30，感染强度范围（RI）为1至6；以及51条鞭尾线虫科福塔莱萨宫脂线虫（Hysterothylacium fortalezae）的幼虫，P = 26.7%，MI = 6.40，MA = 1.70，RI = 1 - 17。异尖线虫属的感染部位是肠系膜和肝浆膜；而福塔莱萨宫脂线虫的感染部位是肠系膜、腹腔和肝浆膜。本文提供了福塔莱萨宫脂线虫外部结构（主要是后端）扫描电子显微镜下的新形态学数据。这是福塔莱萨宫脂线虫寄生在大西洋月鱼体内的首次报道。
