Pseudorhabdosynochus hirundineus n. sp. is described from specimens collected from the gills of Variola louti off Nouméa, New Caledonia, South Pacific. No diplectanid was found on V. albimarginata from the same location. The male sclerotised quadriloculate organ of P. hirundineus is 42 microm in internal length, with a long posterior tube; and the sclerotised vagina, 36 microm in length, is composed of a long tube with anterior open trumpet and two posterior, heavily sclerotised chambers. The two squamodiscs, each with 11-15 rows of rodlets and no central closed row of rodlets, are dissimilar in shape, the ventral being round and the dorsal being oval. By the morphology of its sclerotised vagina, P. hirundineus appears close to P. epinepheli (Yamaguti, 1938) but it is differentiated from it by the shape of its squamodiscs. Pseudorhabdosynochus spp. previously recorded from epinephelines are parasites of species of Epinephelus and Mycteroperca; this is the first species from a species of Variola.
新种燕尾伪铗钩虫(Pseudorhabdosynochus hirundineus n. sp.)是根据从南太平洋新喀里多尼亚努美阿附近的波纹唇鱼鳃上采集的标本描述的。在同一地点的白缘波纹唇鱼上未发现双鳞盘虫。燕尾伪铗钩虫的雄性硬化四边形器官内长42微米,有一个长的后管;硬化阴道长36微米,由一个前端开口呈喇叭状的长管和两个后端高度硬化的腔室组成。两个鳞片盘各有11 - 15排小杆,没有中央封闭的小杆排,形状不同,腹面圆形,背面椭圆形。根据其硬化阴道的形态,燕尾伪铗钩虫似乎与黄斑伪铗钩虫(Yamaguti,1938)相近,但通过其鳞片盘的形状与之区分。先前记录在石斑鱼上的伪铗钩虫属物种是石斑鱼属和驼背鲈属物种的寄生虫;这是首次从波纹唇鱼属物种中发现的该属物种。
