Host and record: Rhinella schneideri (Werner, 1894) (Co) , Leptodactylus latrans (Steffen, 1815) (= L. ocellatus ). Site of infection: Large intestine.

Material deposited: CECOAL 0 2052663 ( R. schneideri ).

Life cycle: The life cycle of this genus is unknown, but third-stage larvae have been found in snails and fishes, and it is also agreed that snails and fishes are paratenic hosts ( Bartlett & Anderson 1985; Moravec et al. 1995). The adults parasitize mainly turtles, less frequently amphibians and fish, and even one species of bird ( Baker 1987).
