Rhabdostyla elongata sp.nov. is described and figured. This peritrich was found as an epibiont on Lernaea barnimiana, a copepod parasitic on the Nile Perch, Lates niloticus in Lake Albert.
Epistylis articulata Fromentel is recorded as an epibiont of Dolops and Argulus, which parasitize a wide range of fish in Lake Albert.
My thanks are due to Mr M. J. Holden who identified the fish as they were removed from the nets, and to Dr G. Fryer, who identified Lernaea barnimiana and has helped with the literature. I am also grateful for a grant from the Leverhulme Trust which made possible the collection of this material.
