We examined 50 amphibians of 4 species (Bufo marinus, B. nebulifer, Rana berlandieri, and Scaphiopus couchii) from 4 localities in the state of Nuevo León, Mexico. We collected 7 species of digeneans (Cephalogonimus americanus, Clinostomum sp. (metacercariae), Haematoloechus complexus, Halipegus occidualis, Langeronia cf. macrocirra, L. cf. jimenezi, and Megalodiscus americanus) and 1 monogenean (Pseudodiplorchis americana), 3 cestodes (Distoichometra bufonis, Ophiotaenia filaroides, and larvae of 1 proteocephalidean), and 4 nematodes (Cosmocercoides sp., Chabaudgolvania sp., Rhabdias fülleborni, and R. savagei). Eleven host records are new, and the geographic ranges of C. americanus, H. occidualis, P. americana, O. filaroides, Chabaudgolvania sp., Cosmocercoides sp., R. fülleborni, and R. savagei are expanded by these records.
