Xiphinema hangzhouense sp. n. is described from the rhizosphere of Magnolia grandiflora in Hangzhou, China. The new species is characterised by having a monodelphic reproductive system, slim body, total stylet = 186-192 μm long and vulva located anteriorly at 27.6-31.2% of total body length. The new species has a gonad 400-450 μm long with a simple uterus and no Z-organ. The female tail is elongated conoid with a rounded terminus. The species has four juvenile stages and no male was found. The polytomous identification codes of X. hangzhouense sp. n. are A1, B4, C2, D23, E12, F2, G2, H2, I23, J2, K2, L1. The new species is morphologically similar to X. winotoi. Phylogenetic analyses of the 28S rRNA, ITS rRNA, 18S rRNA and partial COI gene sequences of X. hangzhouense sp. n. and some closely related Xiphinema species revealed that the new taxon clustered with high statistical support with X. radicicola and X. setariae.
