珠江水系外来鱼类单殖吸虫研究Ⅱ.清道夫鳃上单殖吸虫中国二新纪录属

Pearl River Water System Alien Fish Monogenea Research Ⅱ.Two New Chinese Genera——Parasitizing the Gills of Hypostomus plecostomus

记述了寄生在珠江水系外来鱼类清道夫Hypostomus plecostomus鳃上的指环虫科Dactylogyridae单殖吸虫中国1新纪录属,1新纪录种,即下口鲶三环虫Trinigyrus hypostomatis Hanek,Molnar & Fernando,1974和锚首虫科Ancyrocephalidae单殖吸虫1新纪录属,1新纪录种,即单侧虫Unilatus unilatus Mizelle & Kritsky,1967,对新纪录属种作了新的形态描述并给出特征图。

Trinigyrus Hanek, Molnar ＆ Femando, 1974 （Monogenea, Dactylogyrinae） and Unilatus Mizelle ＆ Kritsky, 1967 （Monogenea, Ancyroeephalidae） were reported in China for the first time, with the descriptions of two newly recorded species, Trinigyrus hypostomatis Hanek, Molnar ＆ Fernando, 1974 arid Unilatus unilatus Mizelle ＆ Kritsky, 1967. Both species were parasites on the gills of an alien fish Hypostornus plecostomus, from the Pearl River water system, in Guangzhou City, Guangdong Province, China. New descriptions and drawings of the sclerotised parts were given for each species.
