In the present study, 12 species from 10 genera within the infraorder Tylenchomorpha were recovered from soil samples collected in Misan province, southeastern Iraq, and identified using morphological and morphometric characteristics. Among these, Pratylenchus thornei was the most frequent species (15.7%), followed by Tylenchorhynchus zeae (12.3%). The family Tylenchidae is one of the most abundant and diverse nematode families, with a global distribution and diverse feeding habits. Two species of the family were identified. The species Filenchus annulatus was recovered from the rhizosphere of maize. Females of this population had a body length of 393-457 μm, a lateral field with four incisures, a slender stylet measuring 7.3-8.7 μm long, V = 58.8-64.2, and a tail 89-96 μm long, tapering to a pointed or filiform terminus. The second species, Malenchus labiatus was recovered from the rhizosphere of alfalfa. Females of this population had a body length of 399-456 μm, annuli 1.2-1.5 μm wide at mid-body, a lateral field with two crenate incisures, a stylet measuring 8.3-9.8 μm, and a tail 97-111 μm long with a pointed terminus. The morphological and morphometric characters of both populations are consistent with those of the type populations and other reported populations. This study represents the first record of F. annulatus and the genus Malenchus in Iraq.
