Abstract

Introduction: 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.

Materials and methods: 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.

Results: 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.

Conclusions: 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.

标题马蹄莲一新的指格群。

导言：为了加深对亚马孙流域鱼类的单基因类生物的认识，需要开展描述、鉴定和分析方面的研究。这样，集中在这组寄生虫的寄生动物群的数据可以保持最新。基于上述情况，本研究的主要目的是鉴定在位于洛雷托-秘鲁Nanay下游地区的Santa Clara市场获得的M. asterias鳃中的单基因新种。材料和方法：在秘鲁洛雷托-伊基托斯市的“圣克拉拉”市场获得了30个asterias M.标本。据渔民说，标本是在纳内河捕获的。样本于2024年8月至2025年2月期间收集，并在位于洛雷托-秘鲁伊基托斯的“Amazonía秘鲁调查研究所”（IIAP）的“实验室Parasitología y Sanidad Acuícola”进行分析。结果：发现了一种寄生于星形田鼠鳃上的单种蚜蝇新种。santacanthorus sanaclarae n. sp.的特征是：MCO为基部呈喇叭状的直槽管，末端呈细长的扩张体，末端呈弯曲的爪状；一个长附件件，不铰接与MCO基地，呈现为一杆形式的开罐器。结论：本研究首次获得了有关星状芽孢杆菌寄生虫的资料。santaclarae Anacanthorus n. sp.是秘鲁记载的该属的第八个物种。

期刊介绍： Acta Parasitologica is an international journal covering the latest advances in the subject. Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews. The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
