title: Parapharyngodon duniae n. sp. (Nematoda: Pharyngodonidae) in Phrynohyas venulosa (Anura: Hylidae) from the Area de Conservación Guanacaste, Guanacaste, Costa Rica.
abstract: Parapharyngodon duniae n. sp. (Nematoda: Pharyngodonidae) in the large intestine of the veined tree frog, Phrynohyas venulosa, from the Area de Conservación Guanacaste in northwestern Costa Rica is described and illustrated. Parapharyngodon duniae n. sp. represents the 34th species assigned to the genus, the 10th species from the Neotropical Realm, and only the third species to parasitize anurans. It is distinguished from the other Neotropical species by having postbulbar ovaries and a prebulbar excretory pore.
