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 ). References: Savazzini (1930) , González & Hamann (2008) . 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 ). Falcaustra sanjuanensis González, Sanabria and Quiroga, 2013 Host and record: Odontophrynus cf. barrioi (Sj) , Lithobates catesbeianus (Shaw, 1802) (Sj) . Site of infection: Large intestine.
