Abstract

The Amazon is the largest river basin in the world and it is home to the greatest diversity of freshwater fish in the world. Mesonauta festivus is a cichlid popularly known as flag cichlid, widely distributed throughout South America. The diversity of parasites in fish from the Amazon region is still underestimated, due to the high fishes diversity. The Myxozoa class has a universal distribution, with some specimens being pathogenic to some fish. The aim of this work was to describe a new species of Hoferellus in M. festivus. The fish were collected in the lake region, municipality of Tartarugalzinho, in the state of Amapá, Brazil. The new species was found parasitizing the urinary bladder of M. festivus. Spores were 11.5 ±1.1 (10.4-12.6) µm long and 10.9 ±1 (9.9-11.9) µm wide, and polar capsules were equally sized, measuring 4.9 ±0.5 (4.4-5.4) µm long and 3.4 ±0.9 (2.5-4.3) µm wide, with a pyriform shape, convergent with the apical region of the spore. The polar filament was wound with 5 to 6 turns. Morphological, morphometric, molecular and phylogenetic analysis proved that it is a new species of Hoferellus in the Amazon region.

寄生于巴西东亚马孙 Tartarugalzinho 市湖区 Mesonauta festivus（慈鲷：慈鲷科）的一种新的粘虫。

亚马逊河是世界上最大的河流流域，也是世界上淡水鱼种类最丰富的地方。Mesonauta festivus 是一种俗称旗鱼的慈鲷，广泛分布于南美洲。由于鱼类种类繁多，亚马逊地区鱼类寄生虫的多样性仍被低估。粘虫类寄生虫分布广泛，有些标本对某些鱼类具有致病性。这项工作的目的是描述 M. festivus 中的一个 Hoferellus 新种。鱼类采集于巴西阿马帕州塔尔塔鲁加津霍市的湖区。新物种被发现寄生在喜庆鱼的膀胱中。孢子长11.5±1.1（10.4-12.6）微米，宽10.9±1（9.9-11.9）微米，极囊大小相同，长4.9±0.5（4.4-5.4）微米，宽3.4±0.9（2.5-4.3）微米，呈梨形，与孢子顶端收敛。极丝缠绕 5-6 圈。形态学、形态计量学、分子和系统进化分析表明，这是亚马逊地区的一个新物种。
