本文对小睾并殖吸虫的囊蚴、后尾蚴、成虫及虫卵形态作了大样本实验观察,结果表明小睾并殖囊蚴是已报告的具两层囊壁的并殖吸虫囊蚴中之最大者,脱去外壁的囊蚴大小为0.728±0.086×0.703±0.094mm。67％的成虫腹吸盘大于口吸盘,大多数的卵巢结构复杂,23％的标本在腹吸盘以前具盘曲的子宫环。尤其突出的是睾丸特小,为已报告的虫种中之最小者,无分技或仅有1—6个芽状突起,这是本虫种典型而又稳定的种群特征。
In this paper, a large sample of metacercariae, post-cercaria, adult worm and egg morphology of the testes of the testes of the testes were observed. The results showed that the circumcoccodes of the testis The largest, off the outer wall of the metacercaria size of 0.728 ± 0.086 × 0.703 ± 0.094mm. 67% of adult abdominal suction cups are larger than oral suction cups, most have a complex ovary structure, and 23% have a tortuous uterine ring before abdominal suction. Particularly prominent is the small testes, the smallest among the reported species of insects, with no or only 1-6 sprouting processes, a characteristic and stable population characteristic of this species.
