Empruthotrema chisholmae n. sp. is described from specimens recovered from a bull ray Pteromylaeus bovinus (Geoffroy Saint-Hilaire, 1817) at the Oceanogràfic Aquarium in Valencia, Spain. The bull ray was caught in the Spanish Mediterranean (Puerto de Mazarrón, Murcia). The new species resembles 4 others of the same genus ( Empruthotrema dasyatidis Whittington and Kearn, 1992, Empruthotrema kearni Whittington, 1990, Empruthotrema stenophallus Chisholm and Whittington, 2005, and Empruthotrema tasmaniensis Chisholm and Whittington, 1999) in having a haptor with 13 marginal loculi, the posteriormost loculus single and medial. The new species can be distinguished from these other species of the genus by the morphology of the sclerotized male copulatory organ, which is the shortest described. The new species also differs from the other species by the following combination of features: haptor with 13 marginal loculi, the presence of eyespots, the absence of an accessory piece associated with the male copulatory organ, and a long egg appendage (more than 150 µm). Empruthotrema chisholmae is the first species of the genus reported from the Mediterranean.
奇氏真孔吸虫新种（Empruthotrema chisholmae n. sp.）是依据从西班牙巴伦西亚海洋馆的一头公牛鳐（Pteromylaeus bovinus， Geoffroy Saint-Hilaire，1817）体内采集的标本描述的。这头公牛鳐捕获于西班牙地中海海域（穆尔西亚自治区马扎隆港）。该新种与同属的其他4个物种（1992年的达氏真孔吸虫Empruthotrema dasyatidis Whittington和Kearn、1990年的卡氏真孔吸虫Empruthotrema kearni Whittington、2005年的狭茎真孔吸虫Empruthotrema stenophallus Chisholm和Whittington以及1999年的塔斯马尼亚真孔吸虫Empruthotrema tasmaniensis Chisholm和Whittington）相似，其抱器具有13个边缘小室，最后端的小室单一且位于中部。该新种可通过已描述的最短的硬化雄性交配器官的形态与同属的其他物种相区分。新种还在以下特征组合上与其他物种不同：抱器有13个边缘小室、有眼点、无与雄性交配器官相关的附属结构以及有一个长的卵附属物（超过150微米）。奇氏真孔吸虫是该属在地中海报道的首个物种。
