摘　　要：Pratylenchus ekrami from maize(Zea mays)roots in Shenyang and luffa(Luffa cylindrica)roots in Dalian,China,are described in this paper.Nematodes from the two areas were identified consistently,and were characterized by a heavy cephalic sclerotization,extending posteriorly up to two body annuli,stylet 11−13μm long,elongating conoid tail,and becoming thinner from vulva.Males were not found.Pratylenchus ekrami is close to Pratylenchus vulnus,but the most critical characteristics between the two species were the number of lip annuli,stylet size,and shape of stylet knobs.This species is the first reported in China.
