A new species of tree frog, known as the “spring frog,” has been discovered in Costa Rica’s central Pacific region. This tiny frog, measuring less than 4 centimeters, thrives in coffee plantations but is at risk from agrochemicals used in farming. Researchers from the University of Costa Rica and Argentina’s National Council for Scientific and Technical Research confirmed the new species, endemic to Costa Rica.
Rediscovery and Traits
The “Rana de las nacientes” (Isthmohyla nacientes) was initially observed in the 1960s but was misidentified as another species. Genetic and morphological studies in 2021 led to its rediscovery and confirmation. Also known as the “coffee frog,” males have a translucent throat that inflates as they produce a short, high-pitched call at night. These frogs are often found perched on coffee shrubs, far more interested in small insects than the coffee berries.
Risks from Agrochemicals
Researcher Wagner Chaves-Acuna warns about the potential dangers pesticides pose to these amphibians. “These poisons travel through the air and seep through the soil, entering the aquatic systems where tadpoles develop,” Chaves-Acuna explained.
Additional Threats
Besides agrochemicals, the frogs face threats from waste dumping, tourism, and loss of vegetation due to encroachment into protected areas, according to Costa Rica’s National Alliance for the Conservation of Amphibians and Reptiles (ANCAR).
Scientists continue to study and photograph this newly discovered species to better understand its ecology and develop conservation strategies.
