A new nematode species, Philometra diplectri n. sp. (Philometridae), is described from male and female specimens found in unidentified tissues of head and anterior trunk (males) and subcutaneously in the mouth and under the operculum (females) of sand perch, Diplectrum formosum (Linnaeus) (Serranidae, Perciformes), from the northern Gulf of Mexico off Florida (Florida Middle Grounds). Based on light and scanning electron microscopy examination, the new species differs from other congeners parasitizing the subcutaneous tissues, fins, tissues of the buccal cavity, and gill covers or gill arches of marine and brackish-water fishes, mainly in having 8 conspicuously large cephalic papillae of the external circle, the absence of caudal projections, and the shape and small size of the anterior inflation of the esophagus in gravid females, and in possessing 5 pairs of caudal papillae and spicules 66-78 µm long in males. Philometra diplectri is the first known species of this genus whose gravid females are parasitic in the head tissues of serranid fishes.
一种新的线虫物种，斐氏嗜子宫线虫（Philometra diplectri n. sp.）（嗜子宫线虫科），是从在墨西哥湾北部佛罗里达州海域（佛罗里达中陆架）的条纹九棘鲈（Diplectrum formosum）（笛鲷科，鲈形目）的头部和躯干前部不明组织（雄性）以及口腔皮下和鳃盖下（雌性）发现的雄性和雌性标本中描述的。基于光学显微镜和扫描电子显微镜检查，该新物种与寄生于海洋和咸淡水鱼类皮下组织、鳍、口腔组织以及鳃盖或鳃弓的其他同属物种不同，主要在于其外圈有8个明显较大的头部乳突，无尾突，妊娠雌虫食管前部膨大的形状和较小尺寸，以及雄性有5对尾乳突和长66 - 78 µm的交合刺。斐氏嗜子宫线虫是该属第一个已知的妊娠雌虫寄生于笛鲷科鱼类头部组织的物种。
