Specimens of four new nematode species of the family Comesomatidae were isolated from the sediments of littoral zone of South China Sea at the coast of Vietnam and described and illustrated. Sabatieria curvispiculata sp. n. is characterized by the long and slender tail, short cephalic setae and strongly curved spicules in males. Setosabatiera orientalis sp. n. is close to S. australis Riera, Nunez, Brito, 2006, but differs from it in the comparatively shorter and more slender tail, small-er number of amphidial fovea turns, greater number of precloacal supplements in males and shape and structure of spic-ules. Dorylaimopsis intermedia sp. n. is morphologically closest to D. mediterranea Grimaldi-de Zio, 1968 and D. magellanense Chen, Vincx, 1968, but differs from both species in the longer outer labial setae and absence of precloacal supplements in males. D. brevispiculata sp. n. is similar to D. turneri Zhang, 1992 and D. coomansi Muthumbi, Soetaert, Vincx, 1977, but differs from both species in the shape of outer labial sensillae and absence of precloacal supplements in males. A pictorial key for determination of valid species in the genus Setosabatieria Rouville, 1903 is given.
从越南海岸附近的中国南海沿岸浅海沉积物中分离出了四新种海体线虫科线虫标本，并对其进行了描述和绘图。弯刺萨巴线虫新种的特征为尾部长而细，头部刚毛短，雄虫交合刺强烈弯曲。东方刚毛萨巴线虫新种与2006年里埃拉、努涅斯、布里托描述的南方刚毛萨巴线虫相近，但在尾相对较短且更细、头感器窝旋数较少、雄虫泄殖腔前补充器数量较多以及交合刺的形状和结构方面与之不同。中间拟矛线虫新种在形态上最接近1968年格里马尔迪 - 德齐奥描述的地中海拟矛线虫和1968年陈、温克斯描述的麦哲伦拟矛线虫，但在外唇刚毛较长以及雄虫无泄殖腔前补充器方面与这两个物种不同。短刺拟矛线虫新种与1992年张描述的特纳拟矛线虫和1977年穆通比、苏埃塔尔、温克斯描述的库曼斯拟矛线虫相似，但在外唇感觉器形状以及雄虫无泄殖腔前补充器方面与这两个物种不同。给出了1903年鲁维尔建立的刚毛萨巴线虫属有效种的检索表。
