The nematode, Bursaphelenchus mucronatus n. sp. is described from the wood of pine trees (Pinus densiflora) in Japan. This new species is closely related to B. lignicolus from which it differs in having a distinct mucro at the tail terminus of females and larvae. The principal insect vector of this nematode is Monochamus alternatus (Cerambycidae). The nematode is widespread throughout Japan but was not correlated with epidemic disease of pine trees. Inoculation experiments showed that B. mucronatus was not very pathogenic whereas B. lignicolus quickly killed pine trees.
