额尔齐斯河鱼类双身虫科一种属新记录

THE FIRST RECORD OF A NEWLY REPORTED CHINESE DIPLOZOIDAE OF MONOGENEA ON FISHES IN THE ERGIS RIVER

  • 摘要: 研究报道了2009年4月至2013年5月采自新疆北部额尔齐斯河(中国段)东方欧鳊(Abramis brama orientalis Berg, 1949)鳃上的1种双身虫科(Diplozoidae Palombi, 1949)、双身虫亚科(Diplozoinae Palombi, 1949)、双身虫属(Diplozoon Nordmann, 1832)的奇异双身虫(Diplozoon paradoxum Nordmann, 1832)。所获标本与Nordmann (1832)的原始描述基本一致, 仅各部分度量等方面略有差异, 经比较鉴定, 为我国一新记录种。同时, 双身虫属在我国也尚属首次发现, 为我国一新记录属。研究对奇异双身虫的主要形态特征进行了描述并绘制了全图和特征图, 测定其ITS-2 rDNA序列并与GenBank同亚科虫种进行比对, 确定其与欧洲已发现的奇异双身虫相似度达到99.5%, 并对该寄生虫的地理分布特点进行了探讨。

     

    Abstract: Diplozoon paradoxum (Nordmann, 1832) belongs to Platyhelminthes, Monogenea, Diplozoinae, Diplozoon. In this study, we reported this organism collected from the gills of Abramis brama orientalis (Berg, 1949) in the Ergis River (within China) from April 2009 to May 2013. Most of the morphological features of this newly found insect were the same as the original description of Diplozoon paradoxum (Nordmann, 1832), except for a few minor differences in the measurements. The genus, Diplozoon Nordmann, was reported for the first time in China. Here we described the morphological characteristics of this insect and showed the images. We analyzed its ITS2 rDNA sequence and compared the results with the parasite from the same subfamily in the GeneBank. The similarity between the newly found Chinese Diplozoon paradoxum and the European Diplozoon paradoxum was 99.5%. The distribution of Diplozoon paradoxum was also discussed in this paper.
