Two new species of Dorylaimidae from Iran are described using morphology and molecular data. Dorylaimus elegans sp. n. is characterised by 4.41-5.92 mm body length, lip region truncate, distinct from adjoining body by a depression, cuticle with 50-55 longitudinal ridges, odontostyle 42-51 mu m long, thicker than cuticle at its level, didelphic female reproductive apparatus, vulva a small sub-equatorial pore, a variable number of advulval papillae (0-6), both pre- and post-vulval, present in most specimens, female tail elongate, 5.6-7.6 anal body diam. long, with ventrally hooked terminus. Male with 26-30 ventromedian supplements arranged very close to each other, copulatory hump weakly developed, and a convex-conoid tail with blunt terminus. Prodorylaimus reyesi sp. n. is characterised by 2.78-3.33 mm body length, lip region slightly angular and well set off from adjoining body by a depression, odontostyle 26-31 mu m long, thicker than cuticle at its level, didelphic female reproductive apparatus, vulva longitudinal, a variable number of advulval papillae (0-3), both pre- and post-vulval, present in most specimens, tail in both sexes convex-conoid in its anterior part, then narrowing abruptly to a filiform hyaline appendix, longer in female (c' = 11.7-15.5) than in male (c' = 7-7.7), and 19-21 contiguous ventromedian supplements. A compendium of the main morphometric characters of Dorylaimus and a key to species are also provided.
