title: New species of Spauligodon Skrjabin, Schikhobalova & Lagodovskaja, 1960 and Thubunea Seurat, 1914 (Nematoda) from the gastro-intestinal tract of lizards in Iran.
abstract: As part of a faunistic study on helminth parasites of Iranian lizards collected from localities in the north of Isfahan province in Iran, two new nematode species belonging to two different families, Pharyngodonidae Travassos, 1919 and Physalopteroidae Railliet, 1893, were found and are, hereby, described. Spauligodon persiensis n. sp. from the large intestine of Cyrtopodion scabrum Heyden is characterised by its imperceptible lateral alae, lack of spicule, different shape of the genital curtain, position of last pair of papillae, aspinose tail in males, position of the vulva and excretory pore, and a tail filament with six to nine spines in females. Thubunea mobedii n. sp. from the stomach of Laudakia nupta nupta (De Filipi) differs from the other species in the genus by possessing a vulva at level of the posterior portion of the oesophageal-intestinal junction in females, lacking spicules, and having a different number of papillae in males. The present paper provides the results of detailed morphological examination of the two new nematode species, using both light and scanning electron microscopy. Taxonomically important characteristics for the members of the two nematode genera, Spauligodon Skrjabin, Schikhobalova & Lagodovskaja, 1960 and Thubunea Seurat, 1914, are also reviewed.
