Thelazia rhodesi (Spirurida, Thelaziidae) is a parasite of ruminants, which causes ocular infections. Scanning electron microscopy was used to study the surface ultrastructure of adult worms of this nematode. At the anterior end of both sexes, the buccal opening was orbicular. Around the mouth, four pairs of cephalic papillae and two lateral amphids were seen. A pair of lateral cervical papillae was present. In the female, the vulva was located at the anterior part of the body, and the tail end was stumpy with two phasmids near its extremity. In the male, the tail was blunt, without caudal alae, and curved ventrally. There were 14 paired preanal papillae, one single papilla directly anterior to cloaca, one paired postanal papilla, and two phasmids at the posterior end. The spicules were unequal and dissimilar. The cuticle was transversally striated and appeared serrated.
罗氏吸吮线虫（旋尾目，吸吮科）是反刍动物的一种寄生虫，可引发眼部感染。利用扫描电子显微镜研究了这种线虫成虫的表面超微结构。在两性的前端，口孔呈圆形。在口周围，可见四对口乳突和两个侧乳突。有一对侧颈乳突。在雌性中，阴门位于身体前部，尾端短粗，在其末端附近有两个尾感器。在雄性中，尾部钝圆，无尾翼，腹侧弯曲。有14对肛前乳突，在泄殖腔正前方有一个单乳突，一对肛后乳突，以及在后端有两个尾感器。交合刺不等长且不同形。角质层有横向条纹，呈锯齿状。
