Two populations of Xiphinema ingens were recovered and characterised based on morphological, morphometric and molecular data. Interesting morphological variation was observed on the nature of differentiation in uterus of females between both populations, i.e. one population had only a pseudo-Z-organ in the shape of globular bodies, whilst the second population had a similar pseudo-Z-organ but also had crystalloids which varied in size and number and were located near the pseudo-Z-globules or sometimes at some distance from them towards the vagina. Variation was also observed in the shape of tail of juveniles within each population as well as between two recovered populations. Both populations had the same range of morphometric data and formed a fully supported clade in both Bayesian inference (BI) and maximum likelihood (ML) methods of phylogenetic analyses using partial sequences of 28S rDNA D2-D3 and ITS1 regions. The two populations of X. ingens formed a clade with another Xiphinema species native to Iran (X. castilloi) in 28S and two species, X. macroacanthum and X. bernardi, in ITS1 trees.
