Scanning electron microscopy (SEM) has been used to study the tegument and related structures of adult Dicrocoelium dendriticum. Its body shape, suckers, common genital pore, Laurer's canal pore, excretory pore, and cirrus are described as seen under SEM. The tegument is devoid of spines and presents an interlacing, ridged network which covers the entire body. The pattern of ridges on the body surface is not homogeneous; details of the pattern in each region are described. SEM of the body surface reveals the high density of tegumental vesicles on ridge walls and valley floors. The tegument also bears small finger-like projections in certain areas. The authors suppose that the vesicles and finger-like projections of the tegument may well be the same structure in different functional stages. Some considerations on the significance of the tegumental differences in each body region are given. Four types of tegumental papillae occur on the suckers and body surface of D. dendriticum: button, rosette, plate, and domed. The dimensions, shapes, position, and arrangement of the papillae are described.
扫描电子显微镜（SEM）已被用于研究成年枝双腔吸虫的皮层及相关结构。描述了在扫描电子显微镜下观察到的其身体形态、吸盘、共同生殖孔、劳氏管孔、排泄孔和阴茎。皮层无棘，呈现出覆盖整个身体的交错、有脊的网络。体表脊的模式不均匀；描述了每个区域模式的细节。体表的扫描电子显微镜显示脊壁和谷底有高密度的皮层小泡。皮层在某些区域也有小的指状突起。作者推测皮层的小泡和指状突起很可能是处于不同功能阶段的相同结构。对每个身体区域皮层差异的意义进行了一些思考。枝双腔吸虫的吸盘和体表出现四种类型的皮层乳头：纽扣状、玫瑰花结状、板状和圆顶状。描述了乳头的尺寸、形状、位置和排列。
