Two species, one new and one known, were found from Bushehr province, southern Iran, and are herein described based on morphological and molecular data. These include sp. nov. and , both belonging to the ' non- group'. The new dagger nematode is characterised by a body length of 3.54-5.00 mm, a lip region separated from the rest of body by a depression, odontostyle 128-148 μm long, 60-89 μm long odontophore, guiding ring at 107-138 μm from anterior end, female tail rounded to dorsally more convex with small bulge and four juvenile stages. Males have one pair of cloacal and three to five ventromedian single supplements. The new species belongs to morphospecies non- group 5, characterised by having two equally developed female genital branches with uterine differentiation in the form of pseudo-Z-organ along with the rhomboid-shaped crystalloid bodies, and a short, rounded tail ending in a peg. The polytomous identification codes of the new species are A4, B2, C5a5b, D6, E56, F4(5), G23, H2, I34, J5a5b, K3, L2. Morphologically, the new species comes close to several known species (namely, , , , , , and ) belonging to morphospecies group 5. The morphological differences of the new species and the aforementioned species are discussed. The second recovered species, , belongs to the same group and has a pseudo-Z-organ in the shape of globular bodies close to and short, conical, distinctly digitate tail. Integrative diagnosis was completed using molecular data obtained from partial sequences of the D2-D3 region of 28S rDNA, ITS1 rDNA, 18S rDNA, and mtDNA genes.
在伊朗南部布什尔省发现了两个物种，一个是新物种，一个是已知物种，本文根据形态学和分子数据对它们进行了描述。这些物种包括新种和，两者都属于“非组”。这种新的匕首线虫的特征是体长3.54-5.00毫米，唇区与身体其他部分由一个凹陷隔开，口针长128-148微米，口针基部1长60-89微米，引导环距前端107-138微米，雌虫尾部圆形至背部更凸出，有小凸起，有四个幼虫阶段。雄虫有一对泄殖腔和三到五个腹中线单个附器。新物种属于形态物种非组5，其特征是有两个同等发育的雌虫生殖分支，子宫分化为假Z器官形式，还有菱形晶体，尾巴短而圆，末端有一个钉状结构。新物种的多歧分类编码为A4、B2、C5a5b、D6、E56、F4(5)、G23、H2、I34、J5a5b、K3、L2。在形态上，新物种与属于形态物种组5的几个已知物种（即、、、、、和）相近。讨论了新物种与上述物种的形态差异。第二个发现的物种属于同一组，有一个接近球形的假Z器官，尾巴短而圆锥形，明显呈指状。利用从28S rDNA、ITS1 rDNA、18S rDNA和线粒体DNA基因的D2-D3区域部分序列获得的分子数据完成了综合诊断。
