Cichlidogyrus lagoonaris Paperna, 1969 Cichlidogyrus lagoonaris Paperna, 1969: 861, figs 73- 77. Cichlidogyrus gibbus Dossou, 1982: 318, 319, figs 31-33. TYPE MATERIAL. — C. lagoonaris: Holotype: MRAC M.T. 35.929 (Paperna 1979). C. gibbus: Holotype: MNHN Tj137; paratype: MNHN 138. TYPE HOST. — Sarotherodon melanotheron melanotheron Rüppell, 1852. ADDITIONAL HOST. — Tilapia guineensis (Bleeker, 1862). TYPE LOCALITY. — C. lagoonaris: Lake Volta, Ghana. C. gibbus: Ouémé and Couffo, Benin. SITE. — Gills. REMARKS We consider that C. gibbus, which male apparatus is closely related to that of C. lagoonaris, is a junior synonym. Paperna gives Sarotherodon melanotheron heudelotii (Duméril, 1861) as type host for C. lagoonaris coming from Ghana, and yet this fish species is not present in this area (see Paugy et al. 2003), the sub-species from Ghana is S. m. melanotheron, which is considered as the type host (as in Dossou 1982 for C. gibbus).
