艾氏八齿鱼在伊朗西部的克尔曼沙阿省的一棵死亡的蒙代尔松的木材和树皮样品中描述和说明了该种真菌。新种的体长为597（507-700）μm（雌性）和662（636-695）μm（雄性）。角质层是弱环与三个侧线和唇区是偏移。口针长9.6（9-10）μm，基鞘小，排泄孔与体径相近。在后躯体瓣的后面骨针大，背肢长40（38-42）μm，喙突出，先端圆形。雌尾呈圆锥形，逐渐变细，末端尖锐，腹侧有一个简单的短尾。雄尾有6个（2 + 2 + 2）尾乳头和一个发育良好的短突。该新种与已知的四个种A. cibolensis、黑腹拟步行虫A. indicus，A. rutgersiandA.糖。对28 SrRNA基因的部分18 S和D2-D3扩展片段的分子分析证实了其作为一个新种的形态学地位。
Aphelenchoides eldaricusn. sp. is described and illustrated from wood and bark samples of a dead Mondell pine in Kermanshah Province, western Iran. The new species has a body length of 597 (507-700)μm (females) and 662 (636-695)μm (males). The cuticle is weakly annulated with three lateral lines and the lip region is offset. The stylet is 9.6 (9-10)μm long with small basal swellings and the excretory pore is locatedcaone body diam. posterior to the metacorpus valve. The spicules are large with the dorsal limb 40 (38-42)μm long with a prominent rostrum and rounded apex. The female tail is conical, tapering gradually to an acute terminus with a simple ventral mucron. The male tail bears six (2 + 2 + 2) caudal papillae and a well-developed mucron. The new species belongs to the Group 2 category ofAphelenchoidesspecies and is close to four known species, namelyA. cibolensis,A. indicus,A. rutgersiandA. sacchari. Molecular analyses of the partial 18S and the D2-D3 expansion segments of the 28S rRNA gene confirmed its morphological status as a new species.
