A new species of the genus is described from a natural habitat in Iran. sp. n. is characterized by its 3.62-4.65 mm long body, lip region cap-like and offset by constriction and 13-16 μm wide, odontostyle fusiform and 14-17 μm long, neck 1016-1359 μm long, both parts of the pharynx separated by a short isthmus-like narrowing, pharyngeal expansion occupying 74.2 (73-77)% of total neck length in females and 70.4 (66-72)% in males, female genital system mono-opistho-ovarian, didelphic, anterior genital branch a large uterine sac with a small terminal mass occupying 7-14% of body length, posterior uterus long and tripartite with a Z-like differentiation, = 50-52, caudal region short and rounded (24-41 μm, = 99-161, = 0.5-0.7), spicules 90-105 μm long and 10-13 spaced ventromedian supplements with hiatus. Analysis of D2-D3 28S rDNA sequences of the new species suggests that might not be a monophyletic taxon, a matter that should be confirmed after future research.
在伊朗的一个自然栖息地中描述了该属的一个新物种。新物种的特征为体长3.62 - 4.65毫米，唇区呈帽状，由缢缩分隔且宽13 - 16微米，口针呈纺锤形且长14 - 17微米，颈部长1016 - 1359微米，咽的两部分由短的峡部样狭窄分隔，咽膨大部占雌性总颈长的74.2（73 - 77）%，雄性为70.4（66 - 72）%，雌性生殖系统为单后卵巢、双子宫型，前生殖支为一个大的子宫囊，末端有一小团块，占体长的7 - 14%，后子宫长且分三部分，有Z形分化， = 50 - 52，尾区短且圆（24 - 41微米， = 99 - 161， = 0.5 - 0.7），交合刺长90 - 105微米，腹中线有10 - 13个间隔且有间隙的补充器。对新物种D2 - D3 28S rDNA序列的分析表明，该属可能不是一个单系分类单元，这一问题有待未来研究确认。
