The surface microtopography of Calicophoron papillosum (Stiles & Goldberger) and C. calicophorum (Fischoeder), inhabiting the rumen of sheep, has been studied by SEM. In C. papillosum, conspicuous transverse ridges encircle the mid-body, gradually lessening dorsally towards the posterior end. The general body surface is aspinose and smooth except for minute bead-like tubercles in the circumoral area. Two types of putative sensory structures-domed aciliate papillae and tegumental pits-are present. Their characteristic aggregation in certain regions and their distribution in other parts of the body is described. A unique pattern of ridges, confined only to the base of the genital papilla and the genital atrium, has been observed. In C. calicophorum, tegumental folds encircle the body, these are more numerous near the anterior end and fewer posteriorly. The oral area has numerous concentric folds with domed aciliate papillae; between or on the papillae are tegumental elevated pits from the centre of which a knob-like structure protrudes. These sensory structures occur to a lesser extent in the acetabular area.
利用扫描电子显微镜（SEM）对寄生于绵羊瘤胃的乳头杯殖吸虫（Stiles & Goldberger）和杯殖吸虫（Fischoeder）的体表微观形态进行了研究。在乳头杯殖吸虫中，明显的横向嵴环绕虫体中部，向背侧逐渐变细直至后端。除口周区域有微小的珠状瘤外，虫体体表无棘且光滑。存在两种假定的感觉结构——圆顶状有纤毛乳头和体表凹坑。描述了它们在特定区域的特征性聚集及其在虫体其他部位的分布情况。观察到一种独特的嵴纹模式，仅局限于生殖乳头基部和生殖窦。在杯殖吸虫中，体表褶皱环绕虫体，前端附近较多而后端较少。口区有许多带有圆顶状有纤毛乳头的同心褶皱；在乳头之间或乳头之上是体表隆起的凹坑，从凹坑中心突出一个瘤状结构。这些感觉结构在腹吸盘区域出现的程度较低。
