Abstract

The morphology of Cephalochlamys namaquensis (Cohn 1906) Blanchard (1908), a diphyllid a cestode from the African clawed toad, Xenopus laevis, is examined with respect to variability reported in the literature. The parasite has a high prevalence of infection (68,9%) in the X. laevis population studied and shows a preference for attachment in the anterior duodenum. Approximately 76% of the worms recovered were juveniles. Coracidia had an LT50 of 6 h and transmission is thought to take place in darkness at the sediment/water interface. The copepod Eucydops gibsoni serves as an intermediate host and it is suggested that chaoborid larvae may act as paratenic hosts.
