Atelopus flavescens Duméril and Bibron, 1841

Class: Amphibia > Order: Anura > Family: Bufonidae > Genus: Atelopus > Species: Atelopus flavescens

Atelopus flavescens Duméril and Bibron, 1841, Erp. Gen., 6: 661. Syntypes: MNHNP 803, 256 (2 specimens), according to Guibé, 1950 "1948", Cat. Types Amph. Mus. Natl. Hist. Nat.: 32), RMNH 2208 (2 specimens); MNHNP 803 designated lectotype by Lescure, 1976, Bull. Mus. Natl. Hist. Nat. Paris, Ser. 3, Zool., 377: 478. Type locality: "sur les bords d'un ruisseau, dans une montagne près Cayenne", French Guiana.

Phryniscus flavescens — Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 153.

Atelopus flavescens — Boulenger, 1894, Ann. Mag. Nat. Hist., Ser. 6, 14: 374–375.

Atelopus vermiculatus McDiarmid, 1973, Contrib. Sci. Nat. Hist. Mus. Los Angeles Co., 240: 1. Holotype: LACM 42060, by original designation. Type locality: "along a forest trail paralleling the lower Rivière Matarony, a tributary of the Fleuve Approuague, French Guiana". Synonymy by Lescure, 1976, Bull. Mus. Natl. Hist. Nat. Paris, Ser. 3, Zool., 377: 478. This doubted by Lötters, Haas, Schick, and Böhme, 2002, Salamandra, 38: 166.

English Names

Cayenne Stubfoot Toad (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 39).

Distribution

French Guiana, northeastern coastal region and adjacent Brazil (Amapá) in lowland rainforest (see comment).

Geographic Occurrence

Natural Resident: Brazil, French Guiana

Comment

In the Atelopus flavescens group of Lynch, 1993, Alytes, 11: 77–87. Lescure, 1974, Vie Milieu, Paris, Ser. C, Biol. Terr., 23: 125–141, discussed the status of this species and the former confusion about this name. Lescure and Marty, 2000, Collect. Patrimoines Nat., Paris, 45: 48–49, provided a brief account, including call description, and photo. Lötters, Haas, Schick, and Böhme, 2002, Salamandra, 38: 166, regarded Atelopus vermiculatus as only a possible synonym. 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: 166. Boistel, Lötters, and Blanc, 2005, in Rueda-Almonacid et al. (eds.), Ranas Arlequines: 122–124, provided a brief account, photograph, and map. Lescure, 1981, Amphibia-Reptilia, 2: 209–215, reported on larval morphology and call. Jorge, Ferrão, and Lima, 2020, Diversity, 12 (310): 7, presented phylogenetic evidence that Atelopus flavescens is imbedded within nominal Atelopus hoogmoedi, the implication being that Atelopus hoogmoedi is a species complex. Taucce, Costa-Campos, Carvalho, and Michalski, 2022, Eur. J. Taxon., 836: 96–130, regarded records of Atelopus flavescens from Amapá, Brazil, as only problematically assigned to Atelopus hoogmoedi.
