目前已经报道了伞滑刃属(Bursaphelenchus)内近百种线虫，其共同的形态特征是雄虫的尾部末端具有交合伞。在该属的分类中尚存在同物异名的问题。为此，基于其特征的复杂性，笔者提出根据线虫侧线的数目、尾乳突的排列、是否出现阴门盖、交合刺形状、外分泌孔及后部子宫分支的位置等特征，将该属分为7组，其中4条侧线组为xylophilus, okinawaensis, africanus, fungivorus, cocophilus, kevini和sexdentati；3条侧线组为eggersi, eremus, hofmanni，leoni；2条侧线组为abietinus和sinensis。73种列入上述分组中，24种因为缺乏形态学资料未能列入。交合刺不能用于分组。列入该分组的39种基于亚基核糖体DNA数据的分子树说明了该分组的合理性。另外，Parasitaphelenchinae, Aphelenchoidinae和Ektaphelenchinae亚科中28种线虫基于核糖体大亚基D1—D2区序列生成的分子树显示了它们在Aphelenchoididae科中的系统关系。
