Abstract
Summary Bursaphelenchus pterocarpi n. sp. isolated from Pterocarpus sp. logs imported from Ghana to Ningbo, China, is described and illustrated. The new species is characterised by a female body length of 630-946 μm, lateral field with four lines, a short 12.6-13.9 μm long stylet with small basal swellings, excretory pore located posterior to nerve ring, outstretched reproductive system with amoeboid sperm inside the spermatheca, a well-developed vulval flap, tail conical and straight with a 1.9-4.8 μm long mucron at the tip, and lacking males in both the wild type and fungal-cultured populations. In a concatenated tree, reconstructed on the basis of the partial 18S, full length ITS and partial 28S rDNA D2-D3 sequences, the new species occupied a basal placement to the clade of xylophilus-group and africanus-group species.
