摘　　要：研究记述寄生于海南清澜绿短臂鱼Aprion virescens鳃上的一种分室科单殖吸虫,短臂鱼蚌盘虫Pseudonitzschia uku Yamaguti,1965。所获标本的形态、量度与Yamaguti(1965)的原始描述基本一致;但南海标本的后吸器上具中央锚钩和边缘小钩等几丁质结构,而Yamaguti的描述中无此类结构;原始描述中阴茎表面被向后弯曲的小刺,而南海标本阴茎表面无刺。故此对蚌盘亚科、蚌盘虫属的特征进行了补充修订。该亚科、属及种均为中国新记录。标本保存于华南师范大学生命科学学院鱼类寄生虫学研究室。A capsalid monogenean, Pseudonitzschia uku Yamaguti, 1965, that belongs to Pseudonitzschia, Pseudonitzschiinae, was discovered on the gills of Aprion virescens in Qinglan Bay of Hainan in China. The morphology and size of the specimens were consistent with the original description, except that there were anchors and marginal hooklets on their haptor, and that the recurved spines over the cirrus were missing. Therefore here we updated the description of the characteristics of the Pseudonitzschiinae subfamily and the Pseudonitzschia genus. The subfamily, genus and species were reported for the first time in China. The specimens were deposited in the Lab of Fish Parasitology of Collage of Life Sciences in the South China Normal University. Amended diagnosis of Pseudonitzschiinae： Capsalidae sensu Yamaguti, 1963. Body elliptical flattened. Haptor disc-shaped, sessile, usually folded antero-posteriorly, armed with one pair of anchors and 14 marginal hooklets; indented muscular margin and delicate marginal membrane present; without septa, loculi or papillae. Anterior attachment organ paired, sucker-shaped. One pair of eye spots. Pharynx without constriction. Intestinal limbs with lateral dendritic diverticula, not united posteriorly. Testes numerous, intercecal. Male copulatory pouch muscular, postpharyngeal, consisted of ejaculatory and prostatic ducts; cirrus short, swelled anterior, armed or unarmed. Common genital pore opening ventrally, posterior to the left anterior attachment organ. Ovary single, spherical, pretesticular; Ootype well developed; uterus opened into the common genital pore; vagina opened dorsally at the level of pharynx. Vitellaria co-extensive with intestinal branches; vitelline reservoir immediately sinistral to ovary. Egg tetrahedral, with single filament. Gill parasites of marine teleosts.
