【 摘 要 】

Proctocaccum dorsale n. sp. is described and Caimanicola marajoara Freitas & Lent, 1938 is redescribed based on specimens collected from Caiman crocodilus yacare (Daudin) from the Pantanal Mato-grossense, State of Mato Grosso do Sul, Brasil. This report extends south ward the known geographic distribution of C. marajoara. It is the first record of the genus Proctocaccum in South America, and in the caiman. Proctocaccum dorsale n. sp. differs from the other eight species in the genus by the dorsal location of the anal openings, instead of being lateral or in the posterior extremity of the body.
