REMARKS

Ergens (1981) in Egypt found and re-described C. tiberianus on Tilapia zillii; he indicated that C. tiberianus on Oreochromis niloticus and Haplochromis longirostris found in Uganda by Paperna & Thurston (1969) (with some differences with original descriptions from Ghana or Israel) had to be considered as C. thurstonae . Dossou (1982) in Benin found C. tiberianus on Tilapia zillii, he agreed with Ergens (1981) about the confusion made by Paperna & Th urston (1969) between C. tiberianus and C. thurstonae . Douëllou (1993), according to Ergens (1981), considered that Paperna & Thurston (1969) confused C. tiberianus with C. thurstonae; she added that Paperna (1968, 1969 and 1979) may have made the same error. Pariselle & Euzet (1995c, 1996) found C. tiberianus only from hosts of the sub-genus Coptodon (namely: Tilapia coffea, T.dageti, T.guineensis, T.walteri and T. zillii).All these remarks are leading us to the same conclusion: all individuals described as C. tiberianus from mouthbreeders hosts (genus Oreochromis and Sarotherodon) have been confused with C. thurstonae by Paperna & Thurston (1969) or Paperna (1968, 1969 and 1979).
