摘要

Three species of cichlid fish, Tilapia brevimanus Boulenger, 1911, T. buttikoferi (Hubrecht, 1881), and T. cessiana Thys van den Audenaerde, 1968, from Guinea, Ivory Coast and Sierra Leone (West Africa) were examined for gill parasites for the first time. Six species of Monogenea were found of which one, Cichlidogyrus digitatus Dossou, 1982, had been previously described. Five new species, all belonging to the genus Cichlidogyrus Paperna, 1960, are described herein: C. albareti sp. n., C. hemi sp. n., C. nuniezi sp. n., C. bonhommei sp. n., and C. slembroucki sp.n.
