Five new species of free living marine nematodes belonging to genus Parodontophora are described from intertidal areas of Fujian Province, East China Sea. P. aequiramus sp. nov. is identified by the amphid with the same length of dorsal branch and ventral branch, opisthocephalic setae arranged as (2D-1V)2, precloacal supplements and armilliths present; Parodontophora irregularis sp. nov. is characterized by arranged irregularly opisthocephalic setae, excretory pore near cephalic setae at the anterior part of buccal cavity and precloacal supplements present; Parodontophora huoshanensis sp. nov. can be distinguished by the amphid 0.77-0.83 times the length of the buccal cavity, opisthocephalic setae arranged as (2D-1V)2 and precloacal supplements present; Parodontophora microseta sp. nov. is characterized by the amphid 1.71-2.1 times the length of the buccal cavity, opisthocephalic setae arranged as (1D-1V)2, precloacal supplements present and anterior gonad to the right and posterior gonad to the left of the intestine; Parodontophora paramicroseta sp. nov. is characterized by the amphid 1.35-1.5 times the length of the buccal cavity, opisthocephalic setae arranged as (1D-1V)2, precloacal supplements present and anterior gonad to the left and posterior gonad to the right of the intestine. A pictorial key to the valid species of Parodontophora Timm, 1963 is given.
从中国东海福建省潮间带描述了隶属于副齿线虫属的5种新的自由生活海洋线虫。新种等枝副齿线虫通过其背支和腹支长度相同的头感器、呈(2D - 1V)2排列的后头部刚毛、存在泄殖前补充器和环纹来鉴定；新种不规则副齿线虫的特征是后头部刚毛排列不规则、排泄孔在口腔前部靠近头部刚毛处且存在泄殖前补充器；新种霍山副齿线虫可通过头感器为口腔长度的0.77 - 0.83倍、后头部刚毛呈(2D - 1V)2排列且存在泄殖前补充器来区分；新种微刚毛副齿线虫的特征是头感器为口腔长度的1.71 - 2.1倍、后头部刚毛呈(1D - 1V)2排列、存在泄殖前补充器且前侧性腺在肠的右侧而后侧性腺在肠的左侧；新种近微刚毛副齿线虫的特征是头感器为口腔长度的1.35 - 1.5倍、后头部刚毛呈(1D - 1V)2排列、存在泄殖前补充器且前侧性腺在肠的左侧而后侧性腺在肠的右侧。给出了1963年蒂姆所定副齿线虫属有效种的图解检索表。
