Gastrointestinal Helminths from Three Species of Frogs, Meristogenys orphnocnemis, M. poecilus, and M. whiteheadi (Anura: Ranidae) from Borneo, Malaysia

Three species of Meristogenys frogs (Ranidae) from Borneo, Malaysia were examined for helminths: Meristogenys orphnocnemis (n = 8), M. poecilus (n = 5), and M. whiteheadi (n = 8). We found three species of Nematoda: Cosmocerca ornata, Rhabdias multiproles, and Abbreviata sp. (larvae in cysts). Both C. ornata and R. multiproles are old world in distribution. The most numerous helminths were Abbreviata sp. in M. whiteheadi. The three species of Meristogenys are parasitized by generalist helminths that also infect other species of anurans. Five new host records are reported.
