Based on light and scanning electron microscopical studies, two new gonad-infecting species of Philometra Costa, 1845, P. draco n. sp. and P. radiata n. sp. (Nematoda: Philometridae), are described from the marine perciform fishes Trachinus draco (Linnaeus) and T. radiatus (Linnaeus) (both Trachinidae), respectively, in the Gulf of Hammamet, off the northeastern coast of Tunisia. Philometra draco n. sp. and P. radiata n. sp. can be separated from other gonad-infecting species of this genus by the structures associated to the gubernaculum (e.g. dorsal protuberance, smooth field separating the dorsolateral longitudinal parts), as well as by the length of the body, spicules and gubernaculum. Philometra radiata n. sp. can be distinguished from P. draco n. sp. in having the dorsal side of the gubernaculum distal end provided with a median longitudinal smooth field demarcated by two dorsolateral lamellate parts. These two new species are the first philometrid species described from fishes of the family Trachinidae.
基于光学显微镜和扫描电子显微镜研究，描述了两种新的感染性腺的菲尔ometra属（Philometra Costa，1845）物种，即龙纹菲尔ometra线虫新种（P. draco n. sp.）和辐射菲尔ometra线虫新种（P. radiata n. sp.）（线虫纲：菲尔ometra科），它们分别采自突尼斯东北海岸哈马迈特湾的海生鲈形目鱼类——龙纹杜父鱼（Trachinus draco，林奈）和辐射杜父鱼（T. radiatus，林奈）（均为杜父鱼科）。龙纹菲尔ometra线虫新种和辐射菲尔ometra线虫新种可通过与引带相关的结构（如背侧突起、分隔背外侧纵向部分的光滑区域）以及身体、交合刺和引带的长度与该属其他感染性腺的物种相区分。辐射菲尔ometra线虫新种与龙纹菲尔ometra线虫新种的区别在于，引带远端的背侧有一个由两个背外侧片状部分界定的中间纵向光滑区域。这两个新物种是首次从杜父鱼科鱼类中描述的菲尔ometra科物种。
