To deepen the knowledge of monogenoids associated with Amazonian fish, studies focused on description, identification and analysis are sought. In this way, the data on the parasitic fauna focused on this group of parasites can be kept up to date. Based on the above, the main objective of this research was to identify new species of monogenoids in the gills of M. asterias acquired in the Santa Clara Market, located in the lower area of Nanay, Loreto-Peru.
Thirty specimens of M. asterias were acquired in the "Santa Clara" Market, in the city of Iquitos, Loreto-Peru. According to fishermen, specimens were captured in the Nanay River. Samples were collected between August 2024 and February 2025 and analyzed in the "Laboratorio de Parasitología y Sanidad Acuícola" from "Instituto de Investigaciones de la Amazonía Peruana" (IIAP) in Iquitos, Loreto-Peru.
A new species of Monogenoidea was discovered parasitizing the gills of M. asterias. Anacanthorus santaclarae n. sp. is characterized by presenting a MCO as a straight grooved tube with a flared base, presenting a thin elongated expansion with a curved claw-shaped termination in its distal part; a long accessory piece, not articulated with the MCO base, presented as a rod in the form of a can opener.
This is the first data on the parasites of M. asterias. Anacanthorus santaclarae n. sp. is the eighth documented species of the genus in Peru.
为了加深对与亚马逊鱼类相关的单殖吸虫类的了解，需要开展侧重于描述、鉴定和分析的研究。这样一来，关于这类寄生虫的寄生动物群的数据就能与时俱进。基于上述情况，本研究的主要目的是在位于秘鲁洛雷托省纳奈下游地区的圣克拉拉市场获取的星点美鲶的鳃中鉴定出新的单殖吸虫类物种。
在秘鲁洛雷托省伊基托斯市的“圣克拉拉”市场获取了30尾星点美鲶标本。据渔民称，这些标本是在纳奈河捕获的。样本于2024年8月至2025年2月期间采集，并在秘鲁洛雷托省伊基托斯市的秘鲁亚马逊研究所（IIAP）的“水产寄生虫学与健康实验室”进行分析。
发现一种新的单殖吸虫类物种寄生于星点美鲶的鳃中。圣克拉拉无棘单殖吸虫新种的特征是具有一个呈直槽管状且基部扩张的MCO，在其远端有一个细长的薄扩张部分，末端呈弯曲的爪状；有一个长的辅助片，不与MCO基部相连，呈开罐器形状的杆状。
这是关于星点美鲶寄生虫的首批数据。圣克拉拉无棘单殖吸虫新种是秘鲁该属有记录的第八个物种。
