Ophidascaris excavata Hsü & Hoeppli, 1931 is a poorly known ascaridid parasite reported from the short-tailed pit viper Gloydius brevicaudus (Stejneger) (Reptilia: Viperidae) in China. In the present paper, the detailed morphology of this nematode was studied using light and scanning electron microscopy (SEM) based on newly collected material. The results revealed several important, but previously unreported, morphological features, including the presence of one pair of small, finger-like prolongations on each lip, narrow cervical alae beginning well posterior to the base of the ventrolateral lips and the second pair of postcloacal ventro-lateral papillae being double; in addition, there is no intestinal caecum. These supplementary morphological and morphometric data, especially the detailed morphological features obtained herein under SEM, would help us to understand the relationships of O. excavata with its congeners and enable us to diagnose this species more accurately.
盲蛇蛔线虫（Ophidascaris excavata）是许寿椿和何琦于1931年报道的一种鲜为人知的蛔科寄生虫，在中国短尾蝮（Gloydius brevicaudus (Stejneger)）（爬行纲：蝰蛇科）体内发现。在本文中，基于新采集的样本，利用光学显微镜和扫描电子显微镜（SEM）对该线虫的详细形态进行了研究。结果揭示了几个重要但此前未报道过的形态特征，包括每个唇上有一对小的指状突起、狭窄的颈翼在腹侧唇基部后方较远的位置开始、第二对泄殖腔后腹侧乳突为双乳突；此外，没有肠盲囊。这些补充的形态学和形态测量数据，特别是本文通过扫描电子显微镜获得的详细形态特征，将有助于我们了解盲蛇蛔线虫与其同属物种的关系，并使我们能够更准确地鉴定该物种。
