Bursaphelenchus doui sp. n. isolated in China from coniferous packaging wood imported from Taiwan and Korea, is described and illustrated. The new species belongs to the xylophilus group. It is characterized by a body length averaging 876 and 811 μm for females and males, respectively, a=33 and 29, a 15 μm long stylet, four lateral lines, a long postuterine branch and conoid female tail (c=23) with slightly ventrally bent terminus and a distinct mucro in ventral position, male with large spicules (34-43 μm) with distinct rostrum and cucullus, dorso-ventrally visible terminal bursa and three pairs and a single caudal papillae. The morphological differentiation from other group species is mainly based on the shape of the female tails and the size of the spicules. The new species can be differentiated from B. abruptus, B. xylophilus, B. mucronatus, B. fraudulentus, B. conicaudatus and B. luxuriosae by means of ITS-RFLP patterns.
