摘要: Eight helminth taxa were found parasitizing Chaunus marinus (n = 40) and Cranopsis valliceps from the Parque Estatal Lagunas Yalahau, Yucatan, Mexico. Seven (2 digeneans: Langeronia macrocirra, Mesocoelium monas; 1 acanthocephalan: Oncicola sp.; 3 nematodes: Rhabdias fuleborni, Aplectana itzocanensis, Cruzia morleyi; a nematode larva) in C. marinus, while 4 (all fuelleborni, Ozwaldocruzia sp., present valliceps. Nematodes, particularly A. iztocanensis, showed high prevalence, mean abundance, intensity values for both species of amphibians. The occurrence R. M. monas, L. morleyi these amphibians Yucatan Peninsula confirms their neotropical distribution, presence itzocanensis increases its geographical suggesting preference by neotropical, rather than neartic areas.
