Bursaphelenchus geraerti n. sp., isolated in Tianjin, P.R. China, from packaging wood made of Pinus sp. imported from the United Arab Emirates, is described. It is characterised by the lateral field with three lines, a stylet 13-14 μm long with small basal swellings, excretory pore located posterior to nerve ring, spicule mitten-shaped, ventrally arcuate with lamina smoothly tapering towards distal tip, with a distinct bend near 60% of total length, condylus elongated with rounded tip, rostrum conical with finely rounded tip, and cucullus weakly developed or absent. The bursal flap is wide and spade-like with the posterior margin truncate or rounded and starts posterior to P6 gland papillae. A vulval flap is absent and the tail is conical, strongly ventrally curved with the terminus pointed and sometimes appearing as a mucron. The new species is characterised by morphological and molecular analysis and is close to B. decraemerae, B. gerberae and B. sakishimanus.
