Abstract
Falcaustra costaricae n. sp. from the intestines of the lizard Norops tropidolepis and F. heosemydis n. sp. from the large intestine of the turtle Heosemys depressa are described and illustrated. Falcaustra costaricae represents the 10th Neotropical species assigned to this genus and is distinguished from other Neotropical species by the distribution pattern of caudal papillae (10 preanal, 0 adanal, 12 postanal, and 1 median), length and width of spicules (510–561 μm long, 18–24 μm wide), and absence of pseudosucker. Falcaustra heosemydis represents the 29th Oriental species and is distinguished from other Oriental species by the distribution pattern of caudal papillae (10 preanal, 0 adanal, 12 postanal, and 1 median), length of spicules (790–890 μm), and absence of pseudosucker. Norops tropidolepis was found to harbor 3 species of Nematoda, F. costaricae, Rhabdias anolis, and acuariid larvae, and 2 species of Acanthocephala (centrorhynchid cystacanths and oligacanthorhynchid cystacanths).
