A new species of Baylis, 1923 was found as a parasite of the fish (Agassiz, 1831) from a lake in the Jardim Botânico Bosque Rodrigues Alves, Belém, Brazil. has a smooth buccal capsule and a well-developed basal ring that is armed with four sclerotized tooth-like structures. The male of the new species is similar to the two species that are known from Brazilian fish, Pinto, Fábio, Noronha & Rolas, 1976, and Kohn & Fernandes, 1988, by the absence of the gubernaculum. It differs from these two by the morphology of the buccal capsule, the number are arrangement of the caudal papillae in males, the size and morphology of the spicules and the shape of the tail of both sexes. is the third species discovered in fish from Brazil. This finding extends the geographical distribution of the genus into the Brazilian Amazon.
1923年发现的一种新的贝利斯属物种是巴西贝伦植物园博斯克·罗德里格斯·阿尔维斯湖中的一种鱼类（阿加西，1831年）的寄生虫。它有一个光滑的口腔囊和一个发育良好的基部环，基部环上有四个硬化的齿状结构。新物种的雄性与已知寄生于巴西鱼类的两个物种（平托、法比奥、诺罗尼亚和罗拉斯，1976年；科恩和费尔南德斯，1988年）相似，均无 gubernaculum。它与这两个物种在口腔囊形态、雄性尾乳头数量和排列、交合刺的大小和形态以及两性尾巴形状方面存在差异。这是在巴西鱼类中发现的第三个物种。这一发现将该属的地理分布扩展到了巴西亚马逊地区。
