摘　　要：从厦门大学海滩潮间带泥基质区分离到轴线虫科的两种 .Axonolaimus spinosus Butschli,1 874除在 1 3个乳突状肛前附器 ,长度等测量数值等特征不同以往的描述别外 ,其他方面类似于前人的描述 .拟齿线虫新种 (Parodontophora amoyensis sp.nov)被鉴定为一个新种是由于 :1 )颈毛排列式 ,雌性 2 (2 D+2 V) ;雄性 2 (3D+2 V) ;2 )排泄孔开口于口腔前部腹侧体表等特征显著不同于该属类似种的特征 .Two species of the family Axonolaimidae(Filipjev,1918) were separated from the intertidal mud flat of the Xiamen University sea beach. A.spinosus Butschli,1874 is different from the former description in its 13 clocal supplements and some body measurement, especially its body size. Parodontophora amoyensis sp. nov is regarded as a new species because 1)cervical setae:2(2D+2V) in male and 2(3D+2V) in female, and 2)excretory pore at the level of the anterior portion of the stoma. New key to the species of Parodontophora was given after adding our newly reported species.
