An Array of Frogs Calling in the Peruvian Amazon
4 February 2012
Nine species of frog are seen here. From left to right, and top to bottom: Hypsiboas geographicus, Dendropsophus sarayacuensis, Hypsiboas lanciformis, Hypsiboas punctatus, Scinax chiquitanus, Phyllomedusa palliata, Leptodactylus rhodonotus, Leptodactylus sp., Leptodactylus sp.
All frogs were recorded in the Madre de Dios region of Peru.

New yellow frog discovered in Peru
A new water frog species has been discovered on Pacific slopes of the Andes in central Peru, an area scientists had thought was poor in biodiversity.
The name of the new species Telmatobius ventriflavum comes from the Latin for yellow belly (venter and flavus) and refers to the golden yellow and orange coloration on the body.
Water frogs are a subfamily of frogs endemic to the Andes of South America. The populations of several species of Telmatobius have declined dramatically over the past 30 years, and the genus is now thought to be extinct in Ecuador. These declines have been associated with the spread of the fungal disease chytridiomycosis.
“The discovery of a new species in such arid and easily accessible environments shows that much remains to be done to document amphibian diversity in the Andes,” said the lead author Dr. Alessandro Catenazzi of Southern Illinois University Carbondale.
The study detected the presence of the chytrid fungus, but the impact of chytridiomycosis on the new species is unknown. The authors recommend disease surveillance to prevent outbreaks that might endanger the survival of this endemic species.
The scientific description of the new species is here.
