记述采自广东汕尾青干金枪鱼Thunnus tonggol鼻腔中的1种单殖吸虫——卡氏嗜鼻虫Nasicola klawei (Stunkard,1962) Yamaguti,1968.所获标本的形态结构及大小与原始描述及Yamaguti(1968)、Kohn等(2004)的描述基本一致，但在子宫结构、睾丸数目及后吸器边缘小钩的长度上略有差别.嗜鼻虫属及卡氏嗜鼻虫均为我国新记录，青干金枪鱼为宿主新记录
This paper reports a capsalid species of monogenean in China. Nasicola klawei (Stunkard, 1962) Yamaguti, 1968 (Monogenea: Capsalidae) was found in the nosal capsule of longtail tuna, Thunnus tonggol (Bleeker, 1851), from Shanwei city, Guangdong Province. The specimens are basically consistent with the original description of Stunkard (1962) and the redescription of Yamaguti (1968) and Kohn et al. (2004) except for some differences in the structure of uterus, number of testes and the length of marginal hooks. This is the first time the genus Nasicola and species N. klawei are recorded in China, and the fish Thunnus tonggol is a new host. The specimens are deposited in the Lab of Fish Parasitology, College of Life Science, South China Normal University.
