Infection of Oxydoras kneri by the acanthocephalan Paracavisoma impudica is described. The parasites do not penetrate deeply into the host gut wall and do not reach the muscularis layers. Host reaction is minimal, consisting of limited fibrosis around the proboscides. Haemorrhages and lymphocyte infiltration are not observed, and phagocytic cells are only present occasionally. Oxydoras kneri is a newly reported host for Paracavisoma impudica.
