RESUMEN
This report deals with the results of a parasitological study done as part of a post-impoundment ecological study of Middle Letaba Dam, Limpopo Province, South Africa. It involved a seasonal survey protocol with particular attention to the diversity and prevalence of the parasitic fauna of the indigenous fish community of the dam and the role of selected fish-eating birds in the life cycle and distribution of fish helminths. The potential species composition of fish of the dam is provided. Monogenean and clinostomatid parasites encountered are listed and infestation statistics of fish and fish-eating bird hosts are presented. The results of this study also provide information on new distribution and host records of the encountered monogeneans.

During a survey of parasites of fish in Lake St. Lucia, KwaZulu-Natal, South Africa, Dichelyne (Dichelyne) rasheedae was recovered from the intestines of Pomadasys comersonnii and Rhabdosargus sarba, and Spirocamallanus olseni from Rhabdosargus sarba. These are new host and geographical records. Both species of nematodes are redescribed and figured by use of light and scanning-electron-microscopical techniques, and additional morphological data are provided.
