Neopsilenchus citri (Jairajpuri, 1968) Bello, 1972 and Tylenchus bhitaii Maqbool & Shahina, 1987, the species belonging to the family Tylenchidae Örley, 1880 are reported from Iran for the first time. The morphological and morphometric characters of Iranian populations of the two species are discussed and illustrated. Iranian population of N. citri is characterised by having a 738.5-928 μm long body, rounded and unstriated head, lateral field with four lines, slender and weak stylet (12-13.5 μm), postvulval uterine sac less than one body width long, 10-12.5 µm and filiform tail with acute terminus (73.5-94 μm). Compared to the morphological characters and morphometric data given in original description, there were no differences between both the populations. The Iranian population of T. bhitaii is morphologically and morphometrically similar to the original population. It is characterised by having a body length of 600-668 μm, stylet length of 10-11 μm, cuticular annulations 1.0-1.5 μm width at mid body, for lines in lateral fields, postvulval uterine sac 10-17 μm and curved tail length 60-68 μm with rounded smooth terminus.
