Chroniodiplogaster formosiana sp. n. (Rhabditida: Diplogastridae) is described from a population of Odontotermes formosanus Shiraki (Isoptera: Termitidae) collected from dead (unidentified) wood at Dinghu Park, China. Characters of C. formosiana which separate it from C. aerivora (Cobb) are a longer tail, the presence of four micropapillae (quadriform condition), and the adjacent position of the second and third macropapillae on the male tail. The diplogasterid Pristionchus uniformis Fedorko & Stanuszek, which is transferred to Chroniodiplogaster, can be distinguished from both C. formosiana and C. aerivora by the position of its excretory pore. Variable results in experimental infection trials suggest that some still unknown factor or factors are important in the infection process. Further studies are necessary to better define these factors before C. formosiana can be considered as a biological control agent of the Formosan termite.
新种台湾长双胃线虫（Chroniodiplogaster formosiana sp. n.，小杆目：双胃线虫科）采自中国鼎湖公园死亡（未鉴定）木材中的台湾白蚁（Odontotermes formosanus Shiraki，等翅目：白蚁科）群体。台湾长双胃线虫与通气长双胃线虫（Chroniodiplogaster aerivora (Cobb)）相区分的特征包括：尾部更长、存在四个微乳头（四边形状态）以及雄性尾部第二和第三大乳头相邻。转移至长双胃线虫属的双胃线虫科的均匀前尖线虫（Pristionchus uniformis Fedorko & Stanuszek）可通过其排泄孔的位置与台湾长双胃线虫和通气长双胃线虫区分开来。实验感染试验的结果不一，表明在感染过程中一些仍未知的因素很重要。在台湾长双胃线虫可被视为台湾白蚁的生物防治剂之前，有必要进行进一步研究以更好地确定这些因素。
