A new species of Tripartiella is described from the gills of the wild saddle cichlid Aequidens tetramerus in north Brazil. Wet smears of skin and gills of examined fish were air-dried at room temperature and impregnated with Klein's dry silver method for examination of the adhesive disc's structures and denticles. Total prevalence of parasitism was 65%. This ciliate is characterized as a small-sized trichodinid, body diameter 37.03 ± 4.9 μm, adhesive disc 30.50 ± 2.71 μm, denticulate ring 13.28 ± 0.8 μm and 24 ± 2.0 denticles. Taxonomic and morphometric data for the new species are discussed.
在巴西北部野生鞍丽鱼（Aequidens tetramerus）的鳃中发现了一种新的三盘虫属（Tripartiella）物种。将检查的鱼的皮肤和鳃的湿涂片在室温下风干，并用克莱因氏干银法浸渍，以检查附着盘的结构和小齿。寄生虫感染的总发生率为65%。这种纤毛虫被鉴定为小型车轮虫科，体直径37.03±4.9μm，附着盘30.50±2.71μm，齿状环13.28±0.8μm，有24±2.0个小齿。文中讨论了该新物种的分类学和形态测量数据。
