Pseudocapillaria moraveci sp. n. (Nematoda, Capillariidae) is described from the stomach of Gobius paganellus Linnaeus (Perciformes, Gobiidae) from rocky shores of the Vigo estuary (Northwest Atlantic coast of Spain). Scanning electron microscopy reveals the absence of a dorsal cuticular membrane interconnecting the caudal lobes of male, thus confirming the assignment of this new species to the nominotypical subgenus Pseudocapillaria Freitas, 1959. Pseudocapillaria moraveci can be easily differentiated from other marine congeneric species belonging to subgenera Pseudocapillaria and Ichthyocapillaria Moravec, 1982 by its muscular oesophagus, which is distinctly thickened at the distal third, the terminal or almost terminal anus in female, the presence of a basal internal papilla on each ventrolateral caudal lobe in male, and its exclusive site preference for the stomach. In addition, the spicule, which measures 0.180-0.292 mm in length (4.9-7.9% of body length) and possesses a proximal end expanded and oblique in lateral view, a narrowed middle part, and a distal end almost pointed, also distinguishes this species. Pseudocapillaria moraveci is, together with P. tomentosa (Dujardin, 1843) Moravec, 1987, the only species in the genus Pseudocapillaria that has been reported to infect members of the family Gobiidae.
莫氏伪毛细线虫新种（线虫纲，毛细科）是从西班牙西北大西洋海岸维哥河口岩石海岸的帕氏虾虎鱼（鲈形目，虾虎鱼科）的胃中发现并描述的。扫描电子显微镜显示雄性尾叶之间没有背角质膜相连，从而确认该新物种属于1959年命名的伪毛细线虫属模式亚属。莫氏伪毛细线虫可以很容易地与属于伪毛细线虫亚属和1982年的鱼毛细线虫亚属的其他海洋同属物种区分开来，其特征在于其肌质食道在远端三分之一处明显增厚，雌性肛门位于末端或几乎位于末端，雄性每个腹侧尾叶上有一个基部内乳突，并且它只寄生于胃部。此外，其交合刺长0.180 - 0.292毫米（占体长的4.9 - 7.9%），在侧面观中近端扩张且倾斜，中部变窄，远端几乎呈尖状，这也使其得以区分。莫氏伪毛细线虫与1987年的绒毛伪毛细线虫（杜雅尔丹，1843）莫拉韦茨一起，是伪毛细线虫属中仅有的两种被报道感染虾虎鱼科成员的物种。
