Five species of toads (Bufonidae) (n = 22) from Peninsular Malaysia were examined for helminths: Duttaphrynus melanostictus, Ingerophrynus parvus, Leptophryne borbonica, Phrynoidis asper, and Rentapia hosii. The helminth community contained 10 species of Nematoda, consisting of mature individuals of Abbreviata bufonis, Aplectana macintoshii, Cosmocerca ornata, Falcaustra pahangi, Meteterakis singaporensis, Oswaldocruzia filiformis, Oswaldocruzia hoepplii, Seuratascaris numidica, and larvae assigned to Ascarididae and Physalopteridae. Nematoda reported in this study are mainly Old World in distribution. Bufonid species from Peninsular Malaysia are infected by generalist nematodes that also infect other anurans. Seven new host records are reported.
