Comment

See comment under Leptopelis brevipes. Removed from the synonymy of Leptopelis rufus by Sollas, 1906, Zool. Rec., 42: 38 (implicitly), and by Noble, 1924, Bull. Am. Mus. Nat. Hist., 49: 234, 331, where it had been placed by Andersson, 1905, Ark. Zool., 2(20): 18. Gabon record by Lötters, Gossmann, Obame, and Böhme, 2001, Herpetofauna, Weinstadt, 23: 32 (including what they later named as Leptopelis crystallinoron. De la Riva, 1994, Rev. Esp. Herpetol., 8: 130, provided a record for Equatorial Guinea. Lasso, Rial, Castroviejo, and De la Riva, 2002, Graellsia, 58: 21–34, provided notes on ecological distribution in Equatorial Guinea. Jackson and Blackburn, 2007, Salamandra, 43: 149–164, provided a record for Nouabale-Ndoki National Park, Rep. Congo. See account for Cameroon by Amiet, 2012, Rainettes Cameroun: 479–486. Schiøtz, 1999, Treefrogs Afr.: 268, provided an account and map. Deichmann, Mulcahy, Vanthomme, Tobi, Wynn, Zimkus, and McDiarmid, 2017, PLoS One, 12 (11: e0187283): 15, noted an unnamed lineage in Gabon previously associated with Leptopelis brevirostrisDewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 13, summarized the literature for Gabon and provided photographs (p. 49). Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 218–219, provided a brief account, photograph, and range map. Status of Leptopelis brevipes was questioned by Mertens, 1965, Bonn. Zool. Beitr., 16: 26-27, which was considered near to Leptopelis brevirostris (Werner) if not a synonym according to J.-L. Perret In Laurent, 1985, In Frost (ed.), Amph. Species World: 229. Lötters, Rödel, and Burger, 2005, Herpetol. J., 15: 151, regarded Leptopelis brevipes as a likely synonym of Leptopelis brevirostrisChanning and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 396, regarded Leptopelis brevipes as too insufficiently known to treat adequately in their fieldguide, and a likely synonym of Leptopelis brevirostrisBell, McLaughlin, Jongsma, Blackburn, and Stuart, 2019, Afr. J. Herpetol., 68: 91–117, reported on geographic variation in both genetics and morphology and placed both Leptopelis crystallinoron and Leptopelis brevipes in synonymy. 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.
