Bursaphelenchus yuyaoensis n. sp. is described and figured from dying Pinus massoniana in Yuyao, China. The new species clearly belongs to the hofmanni group. It is characterised by relatively slim body (a = 43.7 and 36.2 for males and females, respectively), three lines in the lateral field, spicules relatively small (11.4-14.7 mu m), mitten-shaped with the posterior third of the dorsal limb distinctly curved, condylus round and slightly dorsally bent, rostrum well developed with more or less rounded terminus, distal ends of spicules not forming a clear cucullus, male tail with a mucron-like process, female tail slightly ventrally bent with a bluntly rounded terminus, vulval lip not forming a vulval flap and post-uterine sac extending for about half the vulva-anus distance. The separate species status is supported by ITS-RFLP patterns and molecular phylogenetic analysis based on ITS1/2 sequences, which revealed that B. yuyaoensis n. sp. is close to B. parvispicularis and B. paraparvispicularis.
