A new species of pin nematode, Paratylenchus jasmineae sp. n., was isolated and described from the rhizosphere of jasmine in India. The new species can be diagnosed by having a relatively larger body length of 248-355 μm, stylet length of 24.6-28.5 μm, lateral field with four lateral lines, the presence of small post-vulval uterine sac and absence of advulval flaps in the females. Additional morphological characters included continuous lip region with small projected submedian lobes, large and oblong-shaped spermatheca, the presence of prevulval swelling, and arcuate conoid tail with finely rounded terminus. Molecular characterisation of the species was carried out based on internal transcribed spacer sequence (ITS rRNA) and D2-D3 expansion segment of 28S rRNA subunit. Phylogenetic analyses based on ITS and D2-D3 molecular markers resulted in clear separation of P. jasmineae sp. n. from other Paratylenchus species.
