Proctocaecum dorsale n. sp. is described and Caimanicola marajoara Fre
itas & Lent, 1938 is redescribed based on specimens collected from Cai
man crocodilus yacare (Daudin) from the Pantanal Mato-grossense, State
of Mato Grosso do Sul, Brazil. This report extends southward the know
n geographic distribution of C. marajoara. It is the first record of t
he genus Proctocaecum in South America, and in the caiman. Proctocaecu

the dorsal location of the anal openings, instead of being lateral or
in the posterior extremity of the body.
