Abstract
There is some confusion regarding the differentiation of African and Middle Eastern schistosomes with terminal-spined eggs. In an attempt to clarify the situation, the author has separated the members of the genus Schistosoma that have terminal-spined eggs into three broad groups and five species on the basis of egg morphology and certain biological characteristics. The groups are: the haematobium group, with one species (S. haemato-bium); the bovis group, with three species (S. bovis, S. mattheei and S. leiperi); and the inter calatum group, with one species (S. inter-calatum). Further species separation is not thought to be justified yet, and reasons are given for considering S. capense and S. curassoni as synonymous with S. haematobium and S. mattheei respectively.
