During a nematological survey in southern Iran, a population belonging to the family Tylenchidae was recovered from a tomato field in Bushehr province. The recovered population belongs to the genus was described and illustrated herein as n. sp. It is mainly characterized by having a wide and low annulated lip region continuous with adjacent body; amphidial openings confined to the labial plate; four lines in lateral fields forming three bands, with the two outer bands broken by transverse, and the inner one broken by both transverse and longitudinal lines; and median bulb oval with visible valve and elongate-conoid tail uniformly and gradually narrowing toward the distal region, ending in a widely rounded tip. Its morphological and morphometric differences with three closely similar species were discussed. The phylogenetic relationships of the new species with other relevant genera and species were reconstructed using partial sequences of small, and large subunit ribosomal DNA (SSU and LSU rDNA) sequences. Morphometric and morphological data were also provided for an Iranian population of recovered from Bushehr province. Both populations were characterised using SEM data.
在伊朗南部进行线虫学调查期间，从布什尔省的一个番茄田中发现了一个垫刃线虫科种群。在此描述并图示了该发现的种群，将其归为新种。它的主要特征包括：宽而低的具环纹唇区与相邻体部连续；双套孔局限于唇盘；侧区有四条线形成三条带，两条外侧带被横线中断，内侧带被横线和纵线中断；中食道球椭圆形，有可见瓣膜，细长锥形尾部向远端均匀逐渐变窄，末端为宽圆形尖端。讨论了它与三个相似近缘物种在形态和形态测量上的差异。利用小亚基和大亚基核糖体DNA（SSU和LSU rDNA）序列的部分序列重建了新物种与其他相关属和物种的系统发育关系。还提供了从布什尔省发现的伊朗种群的形态测量和形态学数据。两个种群均使用扫描电子显微镜数据进行了表征。
