Praesomal nerves in Leptorhynchoides thecatus (Acanthocephala: Rhadinorhynchidae)

Investigated by light microscopy, the nerve pathways are described for the first time in the praesoma of a species of Rhadinorhynchidae. The pathways are described for 18 nerves, eight paired and two single, which originate from the cerebral ganglion and a post-ganglionic cell and terminate in the body wall musculature and the proboscis. The location of three commissures formed by these nerves is also described.
