A lesion nematode collected from the rhizosphere of Artemisia sp. at Mt. Unzen (Nagasaki Pref.) was described as Pratylenchus unzenesis n. sp. The new species is characterized as follows: L=370-470 μm (mean 420); c=12-17 (14); V=75-79% (77); spear=14.5-15.5 μm (14.9); lip annuli=3; tail annuli=21-32 (26); annulated or smooth tail termini. this nematode is distinguished from the similar P. pratensisobrinus by a shorter spear (14.5-15.5 μm (14.9) vs. 15-17 m (16)), undifferentiated short post-vulval uterine branch (U=0.9-2.0 vs. 1.6-2.7 (2.0) and differentiated) and short spicules in male (13-14 μm (13) vs. 17-19 μn (18)). En face pattern of the new species is characteristic as it has sloping and angular edges of the sub-median segments, considered to be a link between Groups 2 and 3 of the face types proposed by CORBETT and CLARK (1983).
