浙江拟扁虫sp.的描述和图解。它有一个强壮的身体，光滑的角质层，有许多孔，在大三角形背齿的后部有两个小的亚腹面齿，在颈部有一个腹中刚毛，在尾巴上有一对刚毛。雌性体长1325-1573 μ m，a = 23.3-31.2，B = 5.5-6.6，c = 13.6-19.4，c' = 2.7-3.6，V = 61.1- 68.1%。利用核糖体DNA的小亚基（SSU）和大亚基（LSU）的D2/D3扩增片段，对已测序的拟谷盗属各物种的系统发育关系进行分析。浙江拟扁虫sp.在形态特征和系统发育分析上与其它相关线虫存在显著差异。
Tripylina zhejiangensis n. sp. is described and illustrated from Zhejiang province, eastern China. It has a robust body, smooth cuticle with numerous pores, two small subventral teeth in the posterior part of the large triangular dorsal tooth, one ventral-median seta in the cervical region and a pair of setae on the tail. Females are characterized by a body length of 1325-1573 mu m, a = 23.3-31.2, b = 5.5-6.6, c = 13.6-19.4, c' = 2.7-3.6 and V = 61.1-68.1%. Small subunit (SSU) and D2/D3 expansion segments of large subunit (LSU) of ribosomal DNA were used to analyze the phylogenetic relationships of sequenced species in the genus Tripylina. Tripylina zhejiangensis n. sp. varied significantly from other related nematodes both in morphological characterizations and phylogenetic analyses.
