Izecksohn's Guanabara Frog

Euparkerella robusta

Declining

Overview

Euparkerella robusta is a species of frog in the family Strabomantidae. It is endemic to the state of Espírito Santo in southeastern Brazil. It has been recorded from the municipality of Mimoso do Sul and the neighboring Atílio Vivacqua. Common name Izecksohn's Guanabara frog has been proposed for it.

Euparkerella robusta faces severe threats from deforestation and habitat fragmentation in Brazil's Atlantic Forest, one of the world's most endangered biomes. Agricultural expansion, particularly cattle ranching and soybean cultivation, continues to reduce the species' already limited range. Urban development and infrastructure projects further fragment remaining forest patches, isolating populations and reducing genetic diversity.

Threat summary

Habitat

This small frog inhabits the leaf litter and understory of Brazil's Atlantic Forest, particularly in areas with dense canopy cover and high humidity. It requires intact forest environments with minimal disturbance, making it highly vulnerable to habitat modification.
