A new monogenean species Neoheterobothrium hippoglossini sp. n. from the gill cavity of Hippoglossina stomata Steindachner, 1876 is described and illustrated. The new species differs from its seven congeners in a number of morphological features and in having a different host. The validity of the genus Neoheterobothrium is discussed. Neoheterobothrium mcdonaldi Payne, 1987 is relegated from the genus and from the subfamily Choricotylinae and placed in one of the remaining subfamilies of the family Diclidophoridae.

W jamie skrzelowej soli wielkogębowej Hippoglossina stomata Steindachner, 1876 złowionej w Pacyfiku, przy brzegu w okolicy miejscowości Huntington Beach znaleziono pięć osobników przywry monogenetycznej. Szczegółowe badania morfologiczne wykazały, że znaleziony pasożyt reprezentuje rodzaj Neoheterobothrium Price, 1943. Badane osobniki różniły się pod względem niektórych cech morfologicznych od innych gatunków należących do tego rodzaju, dlatego też autorzy zdecydowali się uznać go za nowy gatunek, nadając mu nazwę Neoheterobothrium hippo- glossini sp. n. Niniejsza praca zawiera dyskusję dotyczącą rodzaju Neoheterobothrium. W wyniku tej dyskusji Neoheterobothrium mcdonaldi Payne, 1987, został usunięty z rodzaju oraz podrodziny Choricotylinae dojednej z pozostałych podrodzin rodziny Diclidophoridae.

Baseline information on parasitic infections, including monogenean infections on wild fishes, may aid in implementation of proactive measures as opposed to reactive research aimed at crisis control with reference to future aquaculture applications. The aim of this project was to examine the freshwater monogenean fauna of the Vaal Dam, Vaal River system, South Africa. This short communication reports on infection statistics for monogenean species, some representing new locality records. Parasites were collected from host species other than Labeo spp. from the Vaal Dam, during a summer (January 2010) survey. Fish collected using gill nets of varying mesh sizes were weighed and measured. Mucous smears were prepared from the skin and fins with the aid of microscope slides. Fish were killed humanely by severing the spinal cord behind the head. Gills were carefully removed and divided into areas which were separately scraped to investigate potential parasite site preference. The areas examined were dorsal, median and ventral positions on both the anterior and posterior hemibranch. Both mucous smears and gill scrapings were examined with the aid of a stereo microscope. More parasites were collected from the first or second gill arches, the medial position on the gill, and the anterior hemibranch. Preference for either left or right gill set was inconclusive. Spatial distribution of parasites is thought to result from water flow over the gills during respiration. This paper reports a new locality record for the following monogenean species: Quadriacanthus aegypticus, Dactylogyrus extensus, Dactylogyrus minitus, Gyrodactylus kherulensis and Dactylogyrus lamellatus.
