Abstract: | Three species of fish-parasitizing poecilostomatoid copepods are redescribed based on material collected off the coasts of Mauritania and Senegambia. They are: Bomolochus unicirrus Richiardi from Lichia glauca Linnaeus, Taeniacanthus balistae (Claus) from Balistes capriscus Gmelin, and Chondracanthus brotulae Capart from Molva molva (Linnaeus). |
