Bursaphelenchus moensi n. sp., isolated in Tianjin Port, China, from Pinus packaging wood imported from the USA, is described. It is characterised by a lateral field with three lines (two bands), stylet 13.0-14.9 μm long, excretory pore situated at same level as, or slightly posterior to, the nerve ring, spicules 13.0-15.5 μm long, mitten-shaped, condylus high and broad with squared, rounded or pointed end, rostrum triangular or conical with bluntly rounded tip, and cucullus absent, bursa small, starting posterior to P4, narrow oblong to irregular in shape and with an oval central projection, female vulval flap absent, and tail conical with a finely rounded or mucronate terminus. The new species belongs to the hofmanni-group and is most similar to B. paraparvispicularis, B. parvispicularis and B. wuae. It is distinguished from closely related species by morphology, ITS-RFLP patterns and partial 18S, ITS and 28S D2-D3 rDNA gene sequencing results.
