In the original publication Boulenger mentioned other specimens from Rio Benito and Kribi; two of them are figured, but they are not conspecific: one (Figure 2) agrees with the description of Cardioglossa leucomystax, while the other (Figure 1) agrees with Cardioglossa gratiosa Amiet; see Amiet, 1972, Biol. Gabonica, 8: 225 (Amiet, 1985, In Frost (ed.), Amph. Species World: 17). See brief account in Laurent, 1972, Explor. Parc Natl. Virunga, Ser. 2, 22: 22-24. Frétey and Blanc, 2001, Bull. Soc. Zool. France, 126: 381, reported this species from Gabon. Lasso, Rial, Castroviejo, and De la Riva, 2002, Graellsia, 58: 21-34, provided notes on ecological distribution in Equatorial Guinea. Schiøtz, 1963, Vidensk. Medd. Dansk Naturhist. Foren., 125: 32, provided records for Nigeria. Blackburn, Kosuch, Schmitz, Burger, Wagner, Gonwouo, Hillers, and Rödel, 2008, Copeia, 2008: 603-612, redelimited the species to exclude what is now Cardioglossa occidentalisChanning, Rödel, and Channing, 2012, Tadpoles of Africa: 94–95, reported on comparative tadpole morphology. Pauwels, De Bakker, and Maddison, 2017, Herpetol. Rev., 48: 118, provided a record for Ngounié Province, Gabon, and discussed the range. Baptista, Conradie, Vaz Pinto, and Branch, 2019, In Huntley, Russo, Lages, and Ferrand (eds.), Biodiversity in Angola: 258, doubted that this species will be found in Angola.
