De la Riva, 1994, Rev. Esp. Herpetol., 8: 130, provided a record for Equatorial Guinea. Frétey and Blanc, 2002 "2001", Bull. Soc. Zool. France, 126: 384, 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: 30, provided records for Nigeria. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 258–259, provided information on comparative larval morphology.  Jongsma, Tobi, Dixon-MacCallum, Bamba-Kaya, Yoga, Mbega, Mve Beh, Emrich, and Blackburn, 2017, Amph. Rept. Conserv., 11 (1: e144): 8–9, provided a record for southeastern Gabon and briefly discussed habitat and range. Dewynter, Chirio, Melki, Cordier, and Frétey, 2017, Cah. Fondation Biotope, 11: 12, 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: 25, provided a brief account and photographs from the Monts Birougou area of Gabon. Dewynter and Frétey, 2019, Cah.
