Specimens were collected from a single location, Nyabera Swamp, in Kisumu, Kenya in the Lake Victoria Basin. This new species is morphologically similar to members of the<jats:italic>S. haematobium<\/jats:italic>group, currently represented by 8 species parasitizing artiodactyls and primates, including humans.<jats:italic>Schistosoma kisumuensis<\/jats:italic>differs from these species by producing relatively small<jats:italic>Schistosoma intercalatum<\/jats:italic>-like eggs (135\u00b72\u00d752\u00b79 \u03bcm) with a relatively small length to width ratio (2\u00b755). Comparison of approximately 3000-base-pair sequences of nuclear rDNA (partial 28S) and mtDNA (partial<jats:italic>cox1<\/jats:italic>,<jats:italic>nad6<\/jats:italic>, 12S) strongly supports the status of<jats:italic>S. kisumuensis<\/jats:italic>as a new species and as a sister species of<jats:italic>S. intercalatum<\/jats:italic>. The<jats:italic>cox<\/jats:italic>1 genetic distance between these two species (6\u00b73%) is comparable to other pairwise comparisons within the<jats:italic>S. haematobium<\/jats:italic>group. Separation of the Congo River and Lake Victoria drainage basins is discussed as a possible factor favoring the origin of this species.<\/jats:p>","DOI":"10.1017\/s003118200900643x","type":"journal-article","created":{"date-parts":[[2009,7,2]],"date-time":"2009-07-02T14:34:41Z","timestamp":1246545281000},"page":"987-1001","source":"Crossref","is-referenced-by-count":21,"title":["<i>Schistosoma kisumuensis<\/i>n. sp.
