Parapharyngodon jairajpurii n. sp. from the rectum of the yellow-bellied house gecko, Hemidactylus flaviviridis Ruppell, 1835, collected in Dehradun, India, is described, illustrated, and photomicrographed. It represents the eighth species of Parapharyngodon from the Oriental realm and 48th species assigned to the genus. Of the Oriental species, Parapharyngodon jairajpurii n. sp. is most similar to Parapharyngodon adamsoni in that males of both species possess 4 pair of papillae and a smooth anterior cloacal lip, while females of both species possess a stout tail spike, 6 simple lips, and a prebulbar ovary. These two species differ in that males of P. adamsoni have spicules reaching 120 µm in length compared to spicules of P. jairajpurii, which reach 75 µm in length; females of P. adamsoni have smooth egg shells compared to the punctate eggs of P. jairajpurii.
