摘　　要：对云南杜鹃(Azaleaspp.)、百合(Liliumspp.)和玉米(Zeaspp.)根围上分布的3种新记录拟毛刺线虫进行了形态描述,包括玉米根围的较小拟毛刺线虫、杜鹃上的肾形拟毛刺线虫和百合根围的胼胝拟毛刺线虫,上述3个种群全部未见雄虫。与文献描述比较,杜鹃盆苗根围的肾形拟毛刺线虫虫体和a值偏小;食道腺几乎不覆盖肠。百合种球根围的胼胝拟毛刺线虫虫体、b值偏大,a值和V值偏小。玉米根围的较小拟毛刺线虫虫体偏小,a值偏小,齿针偏短。Three new records,including Paratrichodorus minor extracted from maize（Zea spp.）,and Paratrichodorus renifer extracted from Azalea spp.,as well as Paratrichodorus porosus extracted from Lilium spp.,were morphologically described in Yunnan province,China.Male was not found in the three populations.Compared with the description in the literature,Paratrichodorus renifer in potted azalea was smaller in a value and shorter in body length,and there was rarely intestine and pharyngeal overlapping.Paratrichodorus porosus in Lilium spp.was longer in body length and bigger in b value,while both a value and V value were smaller.The body length of Paratrichodorus minor is smaller,and the onchiostylet of this species is shorter,while the a value is smaller.
