Abstract

In the present study, we examined 30 individuals of introduced African cichlids, Oreochromis niloticus and Coptodon rendalli, collected in a river spring of the Pardo River, Paranapanema River basin, southeastern Brazil. Based on morphological and molecular analyses of the partial LSU rDNA gene, we identified four species of monogeneans, Cichlidogyrus tilapiae, C. thurstonae, C. mbirizei, and Scutogyrus longicornis on the gills of O. niloticus, whereas individuals of C. rendalli were infested only with C. papernastrema. This is the first record of C. mbirizei and C. papernastrema in tilapias from Brazil. The ecological consequences of the introduction of exotic species of tilapia such as O. niloticus and C. rendalli along with their monogenean parasites in a wild environment represented by a river spring are discussed. Our new molecular data on Cichlidogyrus and Scutogyrus contribute to the investigation of the phylogenetic interrelationships of these widely distributed genera of monogeneans since their species composition is still unsettled.

巴西一条河泉中罗非鱼（Oreochromis niloticus）和罗非鱼（Coptodon rendalli）（Cichlidae）的寄生虫（Monogenea）。

在本研究中，我们研究了在巴西东南部帕拉纳帕内马河流域帕尔多河的一个河泉中采集的 30 条引进的非洲慈鲷（Oreochromis niloticus 和 Coptodon rendalli）个体。根据对部分 LSU rDNA 基因的形态学和分子分析，我们在 O. niloticus 的鳃上发现了四种单革囊虫，分别是 Cichlidogyrus tilapiae、C. thurstonae、C. mbirizei 和 Scutogyrus longicornis，而 C. rendalli 的个体只受到 C. papernastrema 的侵扰。这是巴西罗非鱼首次出现 C. mbirizei 和 C. papernastrema 的记录。我们讨论了在以河泉为代表的野生环境中引入外来罗非鱼物种（如 O. niloticus 和 C. rendalli）及其单基因寄生虫的生态后果。我们关于 Cichlidogyrus 和 Scutogyrus 的新分子数据有助于研究这些广泛分布的单系类属的系统发育相互关系，因为它们的物种组成仍未确定。

期刊介绍： Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
