New Poison Dart Frog Species Discovered in Panama

Researchers have discovered a bright orange poison dart frog with a unique call in Donoso, Panama.

The frog was described by biologist from the Smithsonian Tropical Research Institute and the Universidad Autónoma de Chiriquí in Panama, and the Universidad de los Andes in Colombia in a new study published this week in Zootaxa.

It was named Andinobates geminisae for Geminis Vargas, "the beloved wife of (coauthor) Marcos Ponce, for her unconditional support of his studies of Panamanian herpetology," according to a Smithsonian Tropical Research Institute press release.

The specimen for this species was collected on Feb. 21, 2011 by Samuel Valdes, who was then the MWH Global Inc. environment office director, and his field assistant, Carlos de la Cruz, in the headwaters of the Rio Cano, in the district of Donoso, Colon Province, Panama

Additional specimens were collected between the Rio Coclé del Norte and the Rio Belen by biologists Marcos Ponce and Abel Batista, then a student at the Universidad Autónoma de Chiriquí, according to the release.

The specimens were deposited in the Museo de Vertebrados at the University of Panama, the Museo Herpetologico de Chiriquí at the Universidad Autonoma de Chiriquí and in the Círculo Herpetologico de Panamá.

"Abel Batista and Marcos Ponce were the first to note the presence of this species," said Cesar Jaramillo, Smithsonian herpetologist, according to the release. "They've known it was there for several years. However, they were not sure if it was only a variety of another poison dart frog species, Oophaga pumilio, which exhibits tremendous color variation. Based on morphological characteristics of the adult and the tadpole, I thought it might be a new species of Andinobates."

The new species was confirmed by Andrew Crawford, professor at Universidad de Los Andes and former STRI postdoctoral fellow, sequenced the DNA.

Since this new frog species appears to be found in only a very small area, habitat loss and collecting for the pet trade are major threats to its existence.

The authors recommend the formulation of special conservation plans to guarantee its survival.

"A. geminisae is included in the captive breeding program of the Panama Amphibian Rescue and Conservation project, a consortium of six zoos and research institutions dedicated to saving amphibians from the chytrid fungal disease, which is decimating amphibians worldwide, and habitat loss," according to the news release.

Genetic information about this species is available in the Barcode of Life Data System and in GenBank.
