Syphacia caudibandata sp. N (Nematoda: Oxyuridae) from a lagomorph host Lepus capensis Linn in Karachi, Sindh, Pakistan.

Syphacia caudibandata was found in the gut of the common hare Lepus capensis (Linn.) in Karachi, Pakistan. The new species is characterized by having a typical caudal region provided with transverse band and bead like structures placed at wellproportioned spaces in the females and one or two cuticular mamelons and relatively short spicules in males. Scanning micrographs of the cuticle show a typical cuticular structure over the mid dorsal body surface. This is the first time that the genus Syphacia has been found in the host, Lepus capensis, in Pakistan.
