扫描电子显微镜照片的斯氏线虫glaseri。S.的男性头颅。glaseri身体轻微肿胀，有六个唇乳头和四个大的头乳头。生殖乳头有11对，外加一个乳头。骨针是独特的，具有短头，明显的轴，长而窄的叶片，骨针尖端有一个腹孔，呈钩状。未观察到软膜。引带比骨针短得多，前端向腹侧弯曲，向后逐渐扩大。通常，头状突和楔状突向前分叉，形成Y形结构。女性头部有六个唇乳头和四个头乳头，外阴可能有或没有增厚的皮瓣。受感染的青少年的侧域模式开始于前部，具有一个切口，该切口在短距离后变成三个、六个、七个和九个切口，分别形成二个、五个、六个和八个脊。在相轴附近，脊的数量逐渐减少到两个宽脊。
Scanning electron micrographs are presented of Steinernema glaseri. The male head of S. glaseri is slightly swollen and bears six labial and four large cephalic papillae. There are 11 pairs of genital papillae plus a single papilla. The spicule is unique with a short head, distinct shaft, long and narrow blade, and a spicule tip which has a ventral aperture and appears hook-like. A velum was not observed. The gubernaculum is much shorter than the spicule, with the anterior end curved ventrally, and enlarged gradually posteriorly. Usually, the capitulum and cuneus are forked anteriorly to form a Y-shaped structure. The female head has six labial and four cephalic papillae, and the vulva may be with or without a thickened flap. The lateral field pattern of the infective juvenile begins anteriorly with one incisure which after a short distance becomes three, six, seven and nine incisures which create two, five, six and eight ridges, respectively. At about the level of the phasmids, the number of ridges gradually decreases to two broad ridges.
