Electron microscopy of the tegument of H. stylosa cysticercoid as compared with that of H. diminuta reveals great variations in the fine structure of the larval tegument of these two species. On the scolex and the inner cyst wall, the tegument of H. stylosa cysticercoid bears typical microtriches; at the level of the anterior pore, the microtriches are flexuous. The tegument of the outer cyst wall appears as a syncytial band with dense material which accumulates in the region below the unit membrane, and the tegument of the cercomer is increased by branchied microvillies. While, the scolex of H. diminuta cysticercoid is unarmed and the tegument of the outer cyst wall bears branched microvillies. The data permit the conclusion that the differentiation of tegumental structures is graduated from the scolex to the cercomer. This differenciation is more or less important according to the parasite and results of successive inductions which affect parts of the cysticercoid. The significance of these findings is discussed in terms of the possible function of these structures and the penetration of substances.
与微小膜壳绦虫相比，豆状带绦虫似囊尾蚴皮层的电子显微镜观察显示，这两种幼虫皮层的精细结构存在很大差异。在头节和内囊壁上，豆状带绦虫似囊尾蚴的皮层有典型的微毛；在前孔水平，微毛呈弯曲状。外囊壁的皮层表现为一条含有致密物质的合胞体带，致密物质积聚在单位膜下方区域，尾器的皮层因分支微绒毛而增加。而微小膜壳绦虫似囊尾蚴的头节无武装，外囊壁的皮层有分支微绒毛。这些数据得出结论：皮层结构的分化从头节到尾器是渐变的。根据寄生虫和影响似囊尾蚴各部分的连续诱导结果，这种分化或多或少具有重要意义。从这些结构的可能功能和物质渗透方面讨论了这些发现的意义。
