Callimedusa tomopterna (Cope 1868)

Syntypes: USNM 6651 (two specimens; lost) .

Type locality: “Rio Napo, or Upper Amazon, below the mouth of the former,” Departamento Loreto, Perú.

Distribution: Regions 4, 5. Colombia, Ecuador, Peru, Bolivia, Brazil, Venezuela, Guyana, Suriname, and French Guiana. In Venezuela, south of Orinoco River, in states of Amazonas, Bolívar, and Delta Amacuro. See list of localities and distribution map in Barrio-Amorós (2009b).

Remarks: Divergence among samples of this species from the upper Amazon and Guianas suggest at least two species may be hidden within the name Callimedusa tomopterna (Faivovich et al. 2010), but a thorough revision is needed to assess this hypothesis.
