摘要
本文记述了寄生于蛙类的枝腺科吸虫一新亚种——柔弱似侧殖吸虫四川亚种Pleurogenoides tener sichuanensis subsp.nov,。新亚种肠支伸至睾丸之前;卵巢近圆形;子宫经虫体左侧前伸,并在肠管、食道和口吸盘区域形成盘曲;生殖孔位于食道水平等特征而不同于指名亚种Pleurogenoides tener tener。新亚种具有食道和子宫末段,睾丸并列,生殖孔位于食道水平等特征而区别于近似种Pleurogenoides ifranensis。
This paper describes a new subspecies of the family Lecithodendriidae. All type specimens are deposited in the Department of Veterinary Science, Sichuan Agricultural University. Pleurogenoides tener sichuanensis subsp. nov. (figs. 1-3)The description is based on 10 specimens from the small intestine of Rana phrynoides in Yaan (30°N, 103°3'E), Sichuan. This new subspecies can be distinguished from nominate subspecies, Pleurogenoides tener tener (Looss, 1898), by the following features: 1. ceca terminating anterior to testes, 2. ovary subglobular, 3. uterus extending forward through the left side of body, 4. having the uterine coils winding in the region of ceca, oesophagus and oral sucker, 5. genital pore situated in the level of oesophagus. Thie new subspecies differs from similar species, Pleurogenoides ifranensis Dollus, 1958, in: 1. having oesophagus and metraterm, 2. testes symmetrically opposed, 3. genital pore situated in the level of oesophagus.
