摘　　要：中华巨囊吸虫(Megacystium sinensis)是从广西猕猴(Macaca mulatta)体内检获的一种小型枝腺科吸虫。本文运用组织形态学方法对该虫形态特征作进一步观察。虫体的排泄囊很大,顶部有两个长35～37μm呈V形管状排泄管,排泄囊壁黏膜单层柱状上皮。卵巢、卵黄腺、梅氏腺与输卵管连接,输卵管连接子宫。阴道开口生殖孔与子宫末端连接,阴道壁具有厚的肌肉质,阴道内有虫卵。雄茎囊很大,椭圆形,雄茎囊开口生殖孔,末端位于腹吸盘背后。雄茎囊内有S弯曲射精管、U形贮精囊和输精管。射精管中段黏膜表面有条束状肌肉组织。输精管位于雄茎囊末端,在腹吸盘背面分成2支与2睾丸内侧连接。本文补充了该虫排泄囊、雄茎囊和雌性生殖器官的形态特征。The Megacystium sinensis was collected as a new genera and new species of Lecithodendriidae from a monkey （Macaca mulatta） in Guangxi, China. This paper reported further observation by histomorphological method of this new species of Lecithodendriidae. The excretory vesicle was very large. The wall of excretory vesicle was single layer columnar epithelium. Two excretory tubes, 35 -37 μm long, V-shaped, existed on the top of excretory vesicle. Ovary, Mehlis gland, Vitellarium linked with one side of the Fallopian tube, while uterus linked with the other side of the Fallopian. Vaginal opening was observed on reproductive hole, while other side of vagina was connected to metraterm. Vagina wall was thick muscle layer. In vagina there were some eggs. Cirrus poach was large and oval in shape, and opened to the genital pore, ending at post dorsal acetabulum. Cirrus poach was filled with a bundle of muscle fibers. Cirrus poach had an S-curved ejaculatory duct, U-shaped seminal vesicle, and vas deferens. In mucosal surface of middle ejaculatory duct there was distribution of bundles of muscle fiber. Vas deferens and seminal vesicle were located at the end cirrus poach.
