Class: Amphibia > Order: Anura > Family: Arthroleptidae > Subfamily: Arthroleptinae > Genus: Cardioglossa > Species: Cardioglossa leucomystax

Arthroleptis leucomystax Boulenger, 1903, Mem. R. Soc. Esp. Hist. Nat., 1: 62. Holotype: BMNH, by original designation; 1947.2.30.44–48 listed as syntypes in museum records, although the locality collection data associated with 1947.2.30.46–48 is Cameroon suggesting that these are not primary types (DRF). Type locality: "Cap Saint Jean, Guinée espagnole [= Equatorial Guinea]".

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, 2002 "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. Dewynter, Chirio, Melki, Cordier, and Frétey, 2017, Cah. Fondation Biotope, 11: 11, provided a brief account and photographs of this species from the Mount Koumouna-Bouali area of Gabon. Dewynter, Frétey, Jongsma, Bamba-Kaya, and Pauwels, 2018, Cah. Fondation Biotope, 18: 24, provided a brief account and photographs from the Monts Birougou area of Gabon. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 9, summarized the literature for Gabon and providedphotographs (p. 45). Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 240–241, provided a brief account, photograph, and range map. See brief account, range map, and photographs for Equatorial Guinea in Sánchez-Vialas, Calvo-Revuelta, Castroviejo-Fisher, and De la Riva, 2020, Proc. California Acad. Sci., Ser. 4, 66: 137–230. Kako-Wanzalire, Mongo, Ilonga, Mapoli, Mbumba, Neema, Tungaluna, Itoka, and Bogaert, 2021, Tropicultura, 39 (1: 1709): 1–19, briefly discussed habitat preference in north-central Dem. Rep. Congo. Blackburn, Nielsen, Ghose, Burger, Gonwouo, Greenbaum, Gvoždík, Hirschfeld, Kouete, Chifundera, Lawson, McLaughlin, Zassi-Boulou, and Rödel, 2021, Ichthyol. & Herpetol., 109: 732, provided molecular evidence for the existence of two species under this name, one containing specimens from Gabon and the Rep. Congo (‘‘leucomystax 1’’) and the other from Cameroon and Nigeria (‘‘leucomystax 2’’).
