Updated geographic distribution and significant additional museum records for the Horned Frog, Ceratophrys calcarata Boulenger, 1890 (Anura: Ceratophryidae), in Venezuela

The genus Ceratophrys is represented in Venezuela by two species: C. cornuta and C. calcarata. Despite being morphologicallyunique amphibians, most of the geographic distribution of C. calcarata in the north of the country has historicallydepended on bibliographic mentions and sightings without voucher specimens that allowed scientific verification. Thepresent work formally reports first museum voucher specimens for the states of Mérida, Trujillo, Yaracuy and Zulia, andadditional specimens that corroborate the presence of the species in Amazonas and Falcón states. Clarifications on unsupportedhistorical records are included, and the importance of certain records is highlighted. These new data will bring upto date the geographic distribution map of the species within Venezuelan territory.
