云南双团棘胸蛙寄生拟发状属吸虫一新种

A New Species of the Genus Gorgoderina( Digenea: Gorgoderidae) in the Paa yunnanensis

在云南禄丰县一平浪刁翎山（25°10＇N、101°90＇E）等地采集的云南双团棘胸蛙（Paa yunnanesis）膀胱内检获一发状科（Gorgoderidae）拟发状属（Gorgoderina）一新种,以采集地命名为禄丰拟发状吸虫Gorgoderina lufengensis sp.nov.。解剖学证据表明,采集的22只云南双团棘胸蛙中有15只感染复殖吸虫,自然感染率68.19%,感染度1~11。新种禄丰拟发状吸虫与拟发状属报道种最显著的区别在于：睾丸规则,而其余种睾丸不规则;口腹吸盘比例及生殖孔开口位置与记录种不同。新种的正、副模式标本保存在云南师范大学生命科学院。本研究为云南双团棘胸蛙寄生虫研究提供基础材料,在云南双团棘胸蛙的保护和经济开发利用方面具有重要的意义。

Gorgoderina lufengensis sp. nov. , a new species of the genus Gorgoderina （Digenea： Gorgoderidae）, was collected from the uri- nary bladder of frog Paa yunnanensis in Diaolingshan mountain of Lufeng Yipinglang county, Yunnan province （25°10＇N,101°90＇E）, Chi- na. Field investigation shows that 15 out of 22 individuals of P. yunnanensis harboring the trematode G. lufengensis sp. nov. , which account to 68.19% of natural infection rate, and the infectiosity was from 1 to 11. Anatomical evidences revealed that there were several significant differences within the new species G. lufengensis sp. nov. and the recorded Gorgoderina species. Such as the species G. lufengensis sp. nov. had two regular testicles and the other Gorgoderina species did not. The sucker ratio and the opening position of the genital duct of the species G. lufengensis sp. nov. were also quite different from recorded species in genus Gorgoderi- na. Both the original specimen and the paratype of the new species G. lufengensis sp. nov. were deposited in the life science school of Yunnan Normal University. The study will provide the basic information of parasite research on the P. yunnanensis, which has an important significance in the protection of species P. yunnanensis and its economic development and utilization.
