Three species of myobatrachid frogs from Borneo, Malaysia were examined for helminths: Leptobrachium abbotti (n = 5), Leptobrachium hendricksoni (n = 6) and Leptobrachium montanum (n = 12). Herein, we establish the initial helminth records for these 3 species. Found were 4 species of Nematoda: Cosmocerca ornata, Meteterakis sp., Oswaldocruzia sp., Cosmocercidae gen. sp. and 1 cestode gen. sp. Leptobrachium abbotti harbored C. ornata and Oswaldocruzia sp.; L. hendricksoni harbored Meteterakis sp. and Cosmocercidae gen. sp.; L. montanum harbored Oswaldocruzia sp. and 1 cestode gen. sp. Six new host records are reported.
