Ultrastructure of the cyst's wall was studied in monocercus type larvae of 5 species of the family Dilepididae: Dichoanotaenia tundra, Particterotaenia porosa, Platyscolex ciliata, Sacciuterina stellifera and Trichocephaloides megalocephala. In all examined cysticercoids the cyst's wall is of identical structure. It differs from the cyst's wall of larvae of the family Hymenolepididae by the character of material filling tegument, by fibrous and muscular, elements forming independent layers, by the absence of myelin-like layer limiting the cyst cavity. In addition to cytons and myofibroblasts in the cyst parenchima there are secretory cells producing electronic dense granules similar to those produced by neurosecretory cells of tape forms of cestodes.
对双叶槽科5种单尾蚴型幼虫的囊壁超微结构进行了研究：苔原双孔绦虫、多孔粒腺绦虫、纤毛扁槽绦虫、星状囊宫绦虫和巨头毛首绦虫。在所有检查的拟囊尾蚴中，囊壁结构相同。它与膜壳绦虫科幼虫的囊壁不同，表现在填充皮层的物质特性、形成独立层的纤维和肌肉成分、不存在限制囊腔的髓鞘样层。除了囊实质中的细胞体和成肌纤维细胞外，还有分泌细胞，产生与绦虫成虫神经分泌细胞产生的电子致密颗粒相似的颗粒。
