摘　　要：2013年,北京口岸入境的新西兰麻中分离到一种短体线虫,通过形态学特征以及基于核糖体r RNA-ITS区及28S r RNA-D2/D3区序列比较,证实其为玻利维亚短体线虫（Pratylenchus bolivianus Corbett,1983）。该线虫的主要形态鉴别特征为：唇区有3个唇环;平均V=80%~82%;尾末端圆而光滑。该线虫至今未在我国发现,这是国际上首次从新西兰种苗中截获。Pratylenchus bolivianus was detected from New Zealand Phormium tenax plant. It is characterised by head with three lip annuli, V=80%-82%, female tail tip smooth and rounded. It is identified by morphological and DNA sequence analysis of the ITS region and 28 S r RNA-D2/D3 gene. This species has not been found in China, and this is the first report of its distribution in New Zealand.
