Larvae of Paragordius varius (Leidy, 1851) were investigated using transmission electron microscopy, providing new observations concerning the cuticular structures of the preseptum, the postseptal gland and the pseudointestine. The cuticle is three-layered but the basal layer is variable in structure. The hooks possess long, intracuticular roots and the stylets have apical teeth. Both postseptal gland and pseudointestine are secretory in function. The postseptal gland is composed of eight cells, which are all connected by a duct leading through the septum into the preseptum. Inside the postseptal gland, the duct wall has numerous pores. The pseudointestine is composed of four cells surrounding a cavity with an amorphous content. A flattened duct within a syncytium with five nuclei leads to a ventral pore close to the posterior end.
