The present work describes myxozoans found in Cyphocharax nagelli (Characiformes: Curimatinae) commonly called "sagüiru" collected from Rio do Peixe Reservoir, São José do Rio Pardo, São Paulo, Brazil. From a total of 38 examined fish, 24 were infected with Henneguya garavelli n. sp. (63% prevalence) and two with Myxobolus peculiaris n. sp. (5% prevalence) in the gills. Spores were studied by staining and fresh spores were observed by differential interference contrast optics. Henneguya garavelli n. sp. differs from Henneguya iheringi, Henneguya occulta, Henneguya cesarpintoi, Henneguya santae, Henneguya pisciforme, Henneguya amazonica, Henneguya striolata, Henneguya leporinicola and Henneguya chydadea in spore length and from Henneguya travassosi, Henneguya adherens, Henneguya malabarica, Henneguya piaractus and also Henneguya chydadea in polar capsule length and tail length. Myxobolus peculiaris n. sp. was very different when compared to other species of Myxobolus in its morphology and the biggest size of spore body. The authors present tables with comparative measurements of Brazilian myxozoan parasites.
本研究描述了在巴西圣保罗州圣若泽杜里奥帕尔多市皮克斯河水库采集的、俗称“sagüiru”的纳氏丽脂鲤（脂鲤目：曲脂鲤科）体内发现的粘孢子虫。在总共检查的38条鱼中，有24条鱼的鳃感染了加拉韦利亨内格孢子虫（新种）（感染率63%），两条鱼的鳃感染了奇特粘体虫（新种）（感染率5%）。通过染色研究孢子，并利用微分干涉相差光学显微镜观察新鲜孢子。加拉韦利亨内格孢子虫（新种）在孢子长度方面与伊氏亨内格孢子虫、隐匿亨内格孢子虫、塞萨尔平托亨内格孢子虫、圣塔亨内格孢子虫、鱼形亨内格孢子虫、亚马逊亨内格孢子虫、条纹亨内格孢子虫、兔形亨内格孢子虫和奇达德亨内格孢子虫不同，在极囊长度和尾长方面与特拉瓦索斯亨内格孢子虫、粘附亨内格孢子虫、马拉巴尔亨内格孢子虫、皮拉库斯亨内格孢子虫以及奇达德亨内格孢子虫也不同。奇特粘体虫（新种）在形态和孢子体最大尺寸方面与其他粘体虫物种相比差异很大。作者列出了巴西粘孢子虫寄生虫比较测量数据的表格。
