English Names

Niger Forest Treefrog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 69).


Rainforests of southeastern Nigeria and Gabon to eastern Dem. Rep. Congo; presumably in southwestern Central African Republic.


Removed from the synonymy of Leptopelis rufus by Ahl, 1931, Das Tierreich, 55: 231, where it had been placed by Noble, 1924, Bull. Am. Mus. Nat. Hist., 49: 242. See account by Laurent, 1973, Ann. Mus. R. Afr. Cent., Tervuren, Ser. Octavo, Sci. Zool., 202: 56-59. Possibly conspecific with Leptopelis macrotis according to Schiøtz, 1999, Treefrogs Afr.: 258. Gabon record by Lötters, Gossmann, Obame, and Böhme, 2001, Herpetofauna, Weinstadt, 23: 32. Frétey and Blanc, 2001, Bull. Soc. Zool. France, 126: 383, reported this species from Gabon. Schiøtz, 1963, Vidensk. Medd. Dansk Naturhist. Foren., 125: 87, provided records for Nigeria. See account for Cameroon by Amiet, 2012, Rainettes Cameroun: 506-512. Schiøtz, 1999, Treefrogs Afr.: 257–258, provided an account and map. Rödel, Emmrich, Penner, Schmitz, and Barej, 2014, Zoosyst. Evol., 90: 21–31, discussed the taxonomic status of this taxon and noted that currently there is a considerable issue as to application of names due to the uncertainty of what clade actually occurs at the type locality of Leptopelis millsoni. These authors suggested maintaining the nomenclatural status quo until appropriate molecular and/or acoustic data could be gathered. Barej, Pfalzgraff, Hirschfeld, Liedtke, Penner, Gonwouo, Dahmen, Grözinger, Schmitz, and Rödel, 2015, Amph. Rept. Conserv., 9(2, Spec. Section): 56–84, reported on larval morphology. Jongsma, Tobi, Dixon-MacCallum, Bamba-Kaya, Yoga, Mbega, Mve Beh, Emrich, and Blackburn, 2017, Amph. Rept. Conserv., 11 (1: e144): 8, provided a record for southeastern Gabon and briefly discussed habitat and range.
