Abstract

Xiphinema hangzhouensesp. n. is described from the rhizosphere ofMagnolia grandiflorain Hangzhou, China. The new species is characterised by having a monodelphic reproductive system, slim body, total stylet = 186-192μm long and vulva located anteriorly at 27.6-31.2% of total body length. The new species has a gonad 400-450μm 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 ofX. hangzhouensesp. n. are A1, B4, C2, D23, E12, F2, G2, H2, I23, J2, K2, L1. The new species is morphologically similar toX. winotoi. Phylogenetic analyses of the 28S rRNA, ITS rRNA, 18S rRNA and partialCOIgene sequences ofX. hangzhouensesp. n. and some closely relatedXiphinemaspecies revealed that the new taxon clustered with high statistical support withX. radicicolaandX. setariae.
