Abstract

The study aimed to isolate and describe the monogenean parasites of the southern mouthbrooder, Pseudocrenilabrus philander (Weber, 1897), an endemic fish species of the Limpopo River basin in southern Africa. During summer and winter between November 2013 and August 2014, 86 specimens of P. philander were collected from the Nwanedi River (South Africa) and Bubi River (Zimbabwe). Monogenean parasites were isolated from the skin, gills and stomach. Morphometric evaluations revealed the presence of six species from three genera: Enterogyrus coronatus Pariselle, Lambert & Euzet, 1991, Gyrodactylus thlapi Christison, Shinn & van As, 2005, Cichlidogyrus philander Douëllou, 1993, Cichlidogyrus tilapiae Paperna, 1960, and Cichlidogyrus sp. 1 and sp. 2. Morphological and metrical characterisations of the species found during the present study are presented in detail. The presence of C. philander from the Nwanedi River as well as E. coronatus and C. tilapiae from the Bubi River represent new geographical records. Pseudocrenilabrus philander is reported for the first time to host C. tilapiae.

非洲南部林波波河流域中部的菲鱼伪crenilabrus（Weber，1897）的单基因寄生虫（Teleostei：丽鱼科）

该研究旨在分离和描述南部育嘴鱼Pseudocrenilabrus philander (Weber, 1897)的单基因寄生虫，这是非洲南部林波波河流域的一种特有鱼类。在2013年11月至2014年8月的夏季和冬季，在南非的恩瓦内迪河和津巴布韦的布比河采集了86份philander P.标本。从皮肤、鳃和胃中分离出单系寄生虫。形态测定鉴定发现有3属6种:冠状肠虫(Enterogyrus coronatus Pariselle, Lambert & Euzet, 1991)， thlapi Gyrodactylus Christison, Shinn & van As, 2005, philander Cichlidogyrus Douëllou, 1993，罗apiae Paperna, 1960, Cichlidogyrus sp. 1和sp. 2。在本研究中发现的物种的形态和测量特征详细介绍。来自Nwanedi河的C. philander以及来自Bubi河的E. coronatus和C. tilapiae的存在代表了新的地理记录。本文首次报道了罗非鱼的寄主伪crenilabrus philander。
