During an investigation on the biodiversity of plant-parasitic nematodes in Misan province (southeast of Iraq), two populations of Pratylenchus thornei were isolated from the rhizosphere of faba bean. The morphological and morphometric data were provided for the recovered populations. Both populations were similar to each other, but they were somewhat different in terms of the tail shape and body length. The tail in the Alkahla population was subcylindrical, tail terminus truncated and sometimes with a small projection. The tail in the Ali-Algharbi population was conical with an almost round to broadly rounded terminus. The morphological and morphometric characters of both populations agree with the type population of the species and some other populations reported from different areas. Molecular phylogenetic analysis of the Iraqi populations of P. thornei using the large subunit ribosomal RNA gene (LSU rDNA D2-D3) and internal transcribed spacer (ITS rDNA) sequences using Bayesian inference (BI), showed that they form maximally supported clades with other sequences of the species. The present study is the first report of P. thornei from Iraq based on morphological and molecular data.
