1983Ascaridoid nematodes of sirenians - a new species in the Senegal manatee.
Jour. Helminthol. 57(1): 69-76. 2 tabs. 15 figs. 1 pl. Mar. 1983.
—Describes Heterocheilus domningi, n.sp., from T. senegalensis, and compares it with H. tunicatus; suggests that the distribution of these parasites supports a South American rather than African origin for manatees. Also reports H. tunicatus from T. manatus.
