摘要
本文描述了寄生于亚马逊河流域特有的杂食性鱼类 Triportheus angulatus (Spix & Agassiz) (Characiformes: Triportheidae)鳃丝的三个新种 Jainus Mizelle, Kritzky & Crane, 1968。Jainus iquitensis n. sp.的特征是阴道的形态，呈钟形，有一个硬质管状的管道，以及钩对 VII 的形态，在该新种中，钩对 VII 的基部膨大，这是其他同系鱼类所没有的特征。Jainus loretoensis n. sp.在 Jainus 种类中是独一无二的，因为其 Y 形腹锚的形态，具有箭头形的浅根和手指形的深根。Jainus sardinae n. sp.的特点是具有细长的小 J 形管，带有乙状附属片，腹锚呈 Y 形，指形深根不明显，浅根末端呈圆形，带有颏形突起。这些发现为之前报道的秘鲁的两个 Jainus 物种增添了三个新物种。
Three new species of Jainus (Monogenoidea: Dactylogyridae) from the gills of Triportheus angulatus (Characiformes: Triportheidae) collected in the Peruvian Amazonia.
Three new species of Jainus Mizelle, Kritzky & Crane, 1968, are described parasitizing the gill filaments of Triportheus angulatus (Spix & Agassiz) (Characiformes: Triportheidae), an omnivorous fish endemic to the Amazon River basin. Jainus iquitensis n. sp. is characterized by the morphology of the vagina, which is bell-shaped, with a canal as a sclerotized tube and the morphology of hook pair VII, which in the new species presents an inflated base, a characteristic not observed in other congeners. Jainus loretoensis n. sp. is unique among Jainus species due to the morphology of its Y-shaped ventral anchors, with an arrow-shaped superficial root and a finger-shaped deep root. Jainus sardinae n. sp. is characterized by presenting a slender, small J-shaped tube with a sigmoid accessory piece and a ventral anchor that is Y-shaped, with inconspicuous finger-shaped deep root and superficial root with rounded ending with a chin-shaped projection. These findings add three new species to the previously reported two Jainus species from Peru.
期刊介绍：
Systematic Parasitology publishes papers on the systematics, taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic), Monogenea, Digenea, Cestoda, Acanthocephala, Aspidogastrea, Cestodaria, Arthropoda (parasitic copepods, hymenopterans, mites, ticks, etc.), Protozoa (parasitic groups), and parasitic genera in other groups, such as Mollusca, Turbelleria, etc. Systematic Parasitology publishes fully illustrated research papers, brief communications, and fully illustrated major revisions. In order to maintain high standards, all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that, in some cases, this may cause problems for the authors, but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa, and the types will be preserved for posterity.
