Remarks:
Erroneously reported from Cameroon (e.g., Hughes 1983; Spawls & Branch 1995) (Chirio & LeBreton 2007).
Older records of from Bioko (e.g., Mertens 1964) probably refer lichtensteini (Böhme 1975).
Records from Mauritania (e.g.; Doucet 1963), Mali (e.g., Papenfuss 1969), and the Gambia (e.g., Håkansson 1981) are based on maculatus
(Hughes 1977, 1983; Joger & Lambert 1996; Pauwels & Meirte 1996; Emms, Jambang, Bahl, Mankali, Paziaud & Barnett 2007).
Records from Chad refer to resimus (Trape, Kodindo, Djiddi, Mad-Toïngué & Kerah 2020).
