Abstract Bursaphelenchus eproctatus n. sp. is described and figured from a dead Japanese black pine, Pinus thunbergii. The new species has a body length of 639 (580-714) μm in the female and 545 (550-595) μm in the male, ratio a = 35.9 (32.6-41.9) in the female and 33.8 (31.5-35.1) in the male, and c and c′ ratios = 14.2 (13.3-15.0) and 2.7 (2.3-3.0), respectively, in the male. A functional rectum and anus are absent, the intestine ending as a blind sac in the female posterior region. The female stylet = 18.8-21.8 μm long and the male stylet = 14.9-19.8 μm, the median bulb is elongate-oval and there are three lines in the lateral field. The spicules are of medium size, 19.8 (18.8-20.8) μm long, and arcuate with a terminal cucullus; there are two pairs of male caudal papillae and the female tail is tapered with a rounded terminus and a clearly annulated dorsal surface near the tail tip. Based upon spicule morphology the new species belongs to the B. piniperdae-group sensu Ryss and is close to B. hunanensis, B. minutus and B. lini. However, the new species is distinguished from these three species by a number of morphological features and morphometric values.
