n. sp. is described and illustrated from soil samples of palm trees in Kermanshah Province, western Iran. The new species is characterized by a body length of 784 (663 to 925) μm in females and 677 to 715 μm in males; a delicate stylet 6 (5 to 7) μm long and six lines in the lateral field; median bulb of pharynx fusiform, nonmuscular, and nonvalvate; isthmus elongate, slender ending to a pyriform basal pharyngeal bulb not overlapping intestine; postvulval uterine sac well developed, 15 (14 to 17) μm long, female tail elongate-conoid with pointed terminus; and male with adanal bursa and spicules 21 to 22 μm long ( = 2). The new species comes close in morphology and morphometrics to five known species of the genus, namely . , . , , , and Molecular analyses of the partial 18S, D2/D3 expansion segments of the partial 28S and internal transcribed spacer (ITS) revealed this as a new species. The sequences of the partial 18S and 28S D2/D3 regions confirmed the close phylogenetic relationship between n. sp. and other anguinids, but is clearly separated from species and should be considered as a valid genus.
新物种是从伊朗西部克尔曼沙阿省棕榈树土壤样本中描述和图示的。新物种的特征为：雌虫体长784（663至925）μm，雄虫体长677至715μm；纤细口针长6（5至7）μm，侧区有六条线；咽的中球呈梭形，无肌肉且无瓣膜；峡部细长，向梨形基部咽球逐渐变细，不与肠道重叠；阴门后子宫囊发达，长15（14至17）μm，雌虫尾部细长呈锥形，末端尖；雄虫有肛侧囊，交合刺长21至22μm（=2）。新物种在形态和形态测量上与该属的五个已知物种相近，即……、……、……、……和……。对部分18S、部分28S的D2/D3扩展片段以及内转录间隔区（ITS）的分子分析表明这是一个新物种。部分18S和28S D2/D3区域的序列证实了新物种与其他长针线虫之间密切的系统发育关系，但该新物种与其他物种明显分开，应被视为一个有效属。
