The study reported the ultrastructure features of the different tegumental layers, musculature and lemnisci of Porrorchis indicus (Das, 1957) Schmidt and Kuntz, 1967 (Acanthocephala, Plagiorhynchidae) from the Egyptian Centropus senegalensis aegyptius from Sharkia Governorate. Different semi-thin and ultrathin sections of the middle portion of the preasomal part of P. indicus were cut using transmission electron microscopy (TEM). The results show that the body wall is formed of five successive layers; epicuticle, striped, felt, radial and basal layer, the later rests on basement membrane (basal lamina) which is followed by a layer of circularly oriented muscle fibers. Peripherally, body wall is covered by a very thin glycocalex.
