A total of four trichodinids of three genera ( Trichodina, Paratrichodina and Tripartiella) subjected to the family Trichodinidae was obtained, and they were Trichodina centrostrigata Basson et al., 1983, Trichodina heterodentata Duncan, 1977, Paratrichodina africana Kazubski & El-Tantawy, 1986 and Tripartiella orthodens Basson & Van As, 1987. Among these species, P. africana was first recorded in China. T. centrostrigata and T. orthodens were first recorded in Guangxi. P. africana was found to be specific to the host and parasitic site. The SPSS statistical software was further applied to conduct the difference analysis on the populations of P. africana. 2015,34(4): 584-593 收稿日期：2015-1-7 DOI：10.11984/j.issn.1000-7083.2015.04.018 分类号：Q958.9 基金项目：国家自然科学基金项目(No.31172068,No.31471980); 重庆市科委项目(No.cstc2010CA1010, No.cstc2014jcyjA80008); 重庆市教委项目(No.KJ1400530) 作者简介：姜艳妍(1990—),女,硕士研究生,研究方向为鱼类寄生虫学 *通讯作者：唐发辉,E-mail:trichodina@126.com 参考文献： 广西水产技术推广总站. 2010. 广西水产病害测报[EB/OL]. http://d.wanfangdata.com.cn/Periodical_hyyyy-scqy201006009.aspx, 6: 45. 黄琪琰. 2004. 水产动物疾病学[M]. 上海: 上海科学技术出版社. 唐发辉, 赵元莙, 陈辉. 2005. 鲫寄生车轮虫一新种的描述[J]. 水生生物学报, 29(1): 75-80. 唐发辉, 赵元莙. 2007. 三种鲫鱼外寄生车轮虫分类学及异齿车轮虫致鳃组织病理学研究——重庆地区淡水车轮虫研究Ⅱ[J]. 重庆师范大学学报, 24(3): 8-11. 肖俊, 甘西, 罗永巨. 2014. 罗非鱼育种研究进展[J]. 湖南科技大学学报: 自然科学版, 29(1): 106-112. 余艳玲, 林勇, 张永德, 等. 2013. 广西地区罗非鱼寄生车轮虫形态分类的研究[J]. 水产学杂志, 26(6): 48-53. 赵元莙: 2013. 网状车轮虫 Trichodina reticulata Hirschman & Partsch, 1955的世界地理分布特点及寄主特异性分析[J]. 内江师范学院学报, 28(2): 14-19. 郑慈英. 1989. 珠江鱼类志[M]. 北京: 科学出版社: 1-6. 周解, 张春光, 甘西, 等. 2006. 广西淡水鱼类志[M]. 南宁: 广西人民出版社: 1-3.
