Leptodactylus petersii (Steindachner 1864) Holotype: Lost; formerly in the NMW. Type locality: “Marabitanas,” Amazonas, Brazil. Distribution: Regions 4, 5. Widely distributed in Amazon Region (Venezuela, Colombia, Peru, Bolivia, Brazil, Guyana, Suriname, and French Guiana) south to the Cerrado in central Brazil. Two recent confirmed records for Venezuelain southern part of Amazonas State and eastern border of Bolívar State. Remarks: In Leptodactylus melanonotus species group sensu De Sá et al. (2014). Sister taxon of L. leptodactyloides. Records of specimens in Venezuelan museum indicates widespread in lowlands of almost all the country, but many specimens could be other species of Leptodactylus melanonotus group; species identification in this group is very challenging. The map in De Sá et al. (2014) is misplaced with that of Leptodactylus pascoensis and only shows two localities in southern Venezuela.
