English Names

Pebas Stubfoot Toad (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 40).


Disjunct populations in Amazon lowlands of Ecuador and eastern Peru, to Guyana and Amazonas, Brazil.


In the Atelopus flavescens group. Cocroft, McDiarmid, Jaslow, and Ruiz-Carranza, 1990, Copeia, 1990: 638, suggested that Atelopus spumarius was a species complex. Rodríguez and Duellman, 1994, Univ. Kansas Mus. Nat. Hist. Spec. Publ., 22: 12, provided a brief account. See discussion by Lötters, 1996, Neotrop. Toad Genus Atelopus: 47. Lötters, Haas, Schick, and Böhme, 2002, Salamandra, 388: 168, regarded Atelopus spumarius as a species complex, removed Atelopus pulcher from its synonymy, and noted that Atelopus spumarius sensu stricto is likely restricted to the upper Amazon Basin of eastern Peru, southeastern Colombia, and Ecuador. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 176. Lötters, Schulte, and Haddad, 2005, in Rueda-Almonacid et al. (eds.), Ranas Arlequines: 126, provided a brief account, photograph, and map. See Cole, Townsend, Reynolds, MacCulloch, and Lathrop, 2013, Proc. Biol. Soc. Washington, 125: 375, for brief account and records for Guyana.
