REMARKS

Dossou (1973), in his PhD thesis on the fish parasites from South Benin, re-described O. pterigyalis (as O. pterygialis) and indicated a new host: Pelmatochromis caudifasciatus Boulenger, 1913 (the species determination of this new host remains uncertain; in fact, it has been synonymised with Parananochromis caudifasciatus (Boulenger, 1913) which is limited to Southern Cameroon, the Northern part of the Congo and the Rio Muni; this distribution excludes the Benin Rivers).
