A new species of the genus was isolated from soil and root samples from the rhizosphere of (Casuarinaceae) in Quang Nam province, Vietnam. This species is characterized by a round-to-hexagonal labial disc, the presence of a labial region, which is continuous or slightly offset from the body with six sectors, lateral sectors of first labial annulus being smaller than the submedian sectors, the presence of six to seven labial annules; the absence of deirids; stylet length 24 to 28 μ m long, body length 776 to 979 μ m long; lateral field with six to eight lateral lines, without areolation at mid-body and with areolation in outer bands at the tail region and a pointed tail terminus. n. sp. most closely resembles in having a non-sclerotized head framework and lacking a bursa in the males. It can be clearly distinguished from all other species of the genus by these characteristics. The combination of morphology, morphometric features, and phylogenetic trees, based on D2-D3 of 28S and ITS rDNA sequences, showed that this new species can be clearly separated from all other sequenced species. This record is the first for in Vietnam. A new species of the genus was isolated from soil and root samples from the rhizosphere of (Casuarinaceae) in Quang Nam province, Vietnam.

从越南广南省木麻黄科木麻黄根际的土壤和根样本中分离出该属的一个新物种。该物种的特征为唇盘圆形至六边形，有唇区，唇区与身体连续或略有偏移，有六个扇区，第一唇环的外侧扇区小于亚中扇区，有六至七个唇环；无侧器；口针长24至28μm，体长776至979μm；侧区有六至八条侧线，身体中部无网纹，尾部外侧带有网纹，尾端尖。新物种在具有未硬化的头部框架和雄性无交合囊方面与[某物种]最为相似。通过这些特征，它可以与该属的所有其他物种明显区分开来。基于28S的D2 - D3和ITS rDNA序列的形态学、形态测量特征和系统发育树的组合表明，可以将这个新物种与所有其他已测序物种清楚地分开。这是该物种在越南的首次记录。从越南广南省木麻黄科木麻黄根际的土壤和根样本中分离出该属的一个新物种。该物种的特征为唇盘圆形至六边形，有唇区，唇区与身体连续或略有偏移，有六个扇区，第一唇环的外侧扇区小于亚中扇区，有六至七个唇环；无侧器；口针长24至28μm，体长776至979μm；侧区有六至八条侧线，身体中部无网纹，尾部外侧带有网纹，尾端尖。新物种在具有未硬化的头部框架和雄性无交合囊方面与[某物种]最为相似。通过这些特征，它可以与该属的所有其他物种明显区分开来。基于28S的D2 - D3和ITS rDNA序列的形态学、形态测量特征和系统发育树的组合表明，可以将这个新物种与所有其他已测序物种清楚地分开。这是该物种在越南的首次记录。
