摘要
本研究报道了寄生于巴西maranh州两种食人鱼（Pygocentrus nattereri Kner和Serrasalmus rhombeus (Linnaeus)）鳃上的单基因类鱼。在s o Bento市的“格兰德”湖捕获了50个纳特纳氏棘虫标本，在皮涅罗市Pericumã河的主河道捕获了50个棘虫标本。共发现14种趾蚜寄生在白蛉和菱形蛉的鳃上。在已鉴定的14种中，有11种是在P. nattereri中发现的：calycinum Amphitecium Boeger & Kritsky, 1988; camelum Amphitecium Boeger & Kritsky, 1988；Boeger & Kritsky, 1988；Boeger & Kritsky, 1988；细胞外层sp。棘龙属1；jegui anacansaurus Van Every & Kritsky, 1992；Anacanthorus mesocondylus Van Every & Kritsky, 1992；Anacanthorus reginae Boeger & Kritsky, 1988；Anacanthorus sciponophallus Van Every & Kritsky, 1992; Anacanthorus thatcheri Boeger & Kritsky, 1992。在S. rhombeus中发现5种：Am；calycinum;点。falcatum;amazon Anacanthorus Van Every & Kritsky, 1992；a . maranhensis n. sp.和Notozothecium sp. Anacanthorus sp. 1与其同系物的MCO形态不同，MCO是一个具有硬化壁和两端尖的扁平管。马南棘鱼的微管形态与其同类不同，微管是一个槽状管。本研究将已报道的指状纲从P. nattereri增加到28个，S. rhombeus增加到26个。
Dactylogyrids (Platyhelminthes: Monogenoidea) from the gills of Pygocentrus nattereri and Serralsamus rhombeus (Characiformes: Serrasalmidae) from the State of Maranhão, Brazil, with the description of a new species of Anacanthorus.
The present study aimed to report monogenoids parasitizing the gills of two species of piranhas from the state of Maranhão, Brazil: Pygocentrus nattereri Kner, and Serrasalmus rhombeus (Linnaeus). Fifty specimens of P. nattereri were caught in the Lake "Grande" in the municipality of São Bento, and 50 specimens of S. rhombeus were caught in the main channel of the Pericumã River, municipality of Pinheiro. Fourteen species of dactylogyrids were found parasitizing the gills of P. nattereri and S. rhombeus. Of the 14 species identified, 11 were found in P. nattereri: Amphitecium calycinum Boeger & Kritsky, 1988, Amphitecium camelum Boeger & Kritsky, 1988; Amphitecium falcatum Boeger & Kritsky, 1988; Amphitecium junki Boeger & Kritsky, 1988; Amphithecium sp.; Anacanthorus sp. 1; Anacanthorus jegui Van Every & Kritsky, 1992; Anacanthorus mesocondylus Van Every & Kritsky, 1992; Anacanthorus reginae Boeger & Kritsky, 1988; Anacanthorus sciponophallus Van Every & Kritsky, 1992 and Anacanthorus thatcheri Boeger & Kritsky, 1992. Five species were found in S. rhombeus: Am. calycinum; Am. falcatum; Anacanthorus amazonicus Van Every & Kritsky, 1992; A. maranhensis n. sp. and Notozothecium sp. Anacanthorus sp. 1 differs from its congeners by the morphology of the MCO, which is a flat tube with sclerotized walls and pointed terminations at both ends. Anacanthorus maranhensis n. sp. differs from its congeners by the morphology of the MCO, which is a trough-shaped tube. This study increases the number of reported dactylogyrids from P. nattereri to 28, and to 26 for S. rhombeus.
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.
