Diplozoidae infects the gills of cyprinid fishes in Africa, Europe, and Asia. Traditionally the hardened internal structures, crucial for identification of diplozoid species, are studied using light microscopy. Recently, the sclerotised haptoral structures of an African diplozoid,  Paradiplozoon vaalense , were successfully isolated and visualised using scanning electron microscopy (SEM). In this paper, the haptoral sclerites of three diplozoid species are compared using SEM for the first time.  Paradiplozoon ichthyoxanthon  and  Paradiplozoon vaalense  occur on  Labeobarbus  and  Labeo  species, respectively, in the Vaal River system, South Africa, while  Diplozoon paradoxum  is widely-distributed in Europe and Asia, infecting several host species.  Diplozoon paradoxum  is a well-studied species, as well as being the type species of the family and ideal for inclusion in an exploratory study for comparative purposes. SEM study of  D .  paradoxum  and  P .  ichthyoxanthon  provided valuable information regarding surface morphology of the attachment structures hitherto not observed. Elaborate morphometric study of the haptoral hooks were incorporated, adding 12 point-to-point measurements to current morphometric characteristics. The results were analysed statistically, and significant differences support absolute separation (100.00%) of the three species following discriminant analysis. These point-to-point measurements could also be used for light microscopical study in the future and aid species delimitation within the Diplozoidae.
