A new species of Spauligodon (Nematoda: Oxyuroidea: Pharyngodonidae) in Cyrtodactylus bintangrendah (Sauria: Gekkonidae) from Peninsular Malaysia.

Spauligodon bintangensis n. sp. from the intestines of Cyrtodactylus bintangrendah (Gekkonidae) from Peninsular Malaysia is described and illustrated. Spauligodon bintangensis n. sp. represents the 51st species assigned to the genus and the first species from the Oriental Region. The new species is most similar to Spauligodon atlanticus, Spauligodon eremiasi, and Spauligodon occidentalis, but is easily separated by position of vulva, prebulbar in S. atlanticus and S. occidentalis , postbulbar in the new species, and location of lateral alae; in S. eremiasi, the lateral alae occur only in the fourth quarter of the body, whereas in the new species the lateral alae begin just posterior to lips.
