Description: The tegument and sensory organs of Nybelinia surmenicola (Cestoda, Trypanorhyncha) were studied with the aim of ultrastructural description and a comparative analysis. The N. surmenicola plerocercoid lacks papillae with sensory cilia on the bothria adhesive surface. The unciliated sensory organ contains the central electron-dense disc, three dense supporting rings, broad root and locates in the basal matrix under the tegument. The tegument has a number of ultrastructural features which makes it significantly different from other Trypanorhyncha: I) the tegumental cytoplasm has a plicated constitution in a form of high apical and deep basal folds; II) numerous layers of the basal matrix are presented in subtegument; III) the squamiform and bristle-like microtriches lack the base and the basal plate. In comparison with other Trypanorhyncha, all Nybelinia species studied have less quantity of the bothrial sensory organs. This fact may reflect behavioral patterns as well as phylogenetic position of Nybelinia into Trypanorhyncha.
