摘要
在对阿根廷Samborombon河辣椒Corydoras paleatus Jenyns, 1842和侧生多齿螟corydoria multidentata Jenyns, 1842的寄生虫调查中，对corydori Trichodina n. sp、cribbi Dove和O 'Donoghue, 2005和T. jenynsii n. sp进行了形态研究。本文介绍了硝酸银浸渍干标本的分类和形态计量学资料。毛霉的特点是叶片突突突出，叶片与中部连接的截面较短，口侧纤毛螺旋旋转370-380°。叶氏毛霉的特征是叶片弯曲，齿状射线突出，成年标本的齿状射线非常长，逐渐变细，形成细尖。本研究是首次在南美洲正式报道这些trichodinids，并对两个新种进行了描述。
Trichodinids (Ciliophora) of Corydoras paleatus (Siluriformes) and Jenynsia multidentata (Cyprinodontiformes) from Argentina, with description of Trichodina corydori n. sp. and Trichodina jenynsii n. sp.
During surveys of parasites of the pepper cory Corydoras paleatus Jenyns, 1842 and sided-livebearer Jenynsia multidentata Jenyns, 1842 from Samborombon River, Argentina, Trichodina corydori n. sp., Trichodina cribbi Dove and O’Donoghue, 2005 and T. jenynsii n. sp. were morphologically studied. Taxonomic and morphometric data for these trichodinids based on dry silver nitrate-impregnated specimens are presented. Trichodina corydori is characterized by a prominent blade apophysis, the section connecting the blade and central part is short, and the adoral ciliary spiral makes a turn of 370–380°. Trichodina jenynsii is characterized by curved blades and prominently-shaped denticle rays that are characteristically extremely long, tapering to thin sharp points in adult specimens. This study is the first formal report of these trichodinids from South America, and the description of two new species.
期刊介绍：
Acta Protozoologica - International Journal on Protistology - is a quarterly journal that publishes current and comprehensive, experimental, and theoretical contributions across the breadth of protistology, and cell biology of Eukaryote microorganisms including: behaviour, biochemistry and molecular biology, development, ecology, genetics, parasitology, physiology, photobiology, systematics and phylogeny, and ultrastructure. It publishes original research reports, critical reviews of current research written by invited experts in the field, short communications, book reviews, and letters to the Editor.
