Abstract

Purpose

Studies on monogeneans parasitizing representatives of Siluriformes in Africa remain scarce and fragmentary. In order to contribute to fill this gap, we screened Heterobranchus longifilis from the Lindi River in the Democratic Republic of the Congo.

Methods

Heterobranchus longifilis was purchased from fishermen in DR Congo, province of Tshopo, in Kisangani town, the Lindi River. The monogeneans were individually isolated from the gill and transferred directly onto a slide in a drop of Hoyer’s medium.

Results

Quadriacanthus lindiensis n. sp. is morphologically similar to Quadriacanthus longifilisi. However, it is distinguished from the latter by its non-sclerotized vagina, its dorsal cunei shape and the size of its bars.

Conclusion

Only Q. lindiensis n. sp. was found on the gills of the single individual of H. longifilis screened. In the future, a representative sampling should enable us to verify if Q. lindiensis n. sp. co-occurs with other species known to parasitize H. longifilis.

来自刚果民主共和国鲶鱼的 Quadriacanthus（单属，Dactylogyridae）：描述来自 Heterobranchus longifilis 的一个新种（远洋鱼类，鳞鳃目）。

目的：关于寄生于非洲绢鱼类代表种的单基因动物的研究仍然很少且零散。为了填补这一空白，我们对来自刚果民主共和国林迪河（Lindi River）的长鳍异鳃鱼（Heterobranchus longifilis）进行了筛选。从鳃中单独分离出单胞藻，并将其直接转移到滴有霍耶氏培养基的载玻片上：结果：Quadriacanthus lindiensis n. sp.在形态上与 Quadriacanthus longifilisi 相似。然而，它与后者的区别在于后者的阴道无硬质化、背部楔形以及条纹的大小：结论：在筛查到的长鳍鳕个体的鳃上只发现了 Q. lindiensis n. sp.。未来，有代表性的取样将使我们能够验证 Q. lindiensis n. sp.是否与其他已知寄生于龙利鱼的物种共存。

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.
