Plectrohyla teuchestes

# Alta Verapaz Spikethumb Frog (Plectrohyla teuchestes) The Alta Verapaz Spikethumb Frog is a small arboreal amphibian endemic to Guatemala's cloud forests. This species belongs to the hylid family and is characterized by its distinctive enlarged thumb spikes, which males use during territorial disputes and mating displays. The frog exhibits typical nocturnal behavior, feeding on small insects and arthropods while occupying the forest canopy. Like other cloud forest amphibians, it likely plays an important role in controlling insect populations and serves as prey for various predators within its ecosystem. This species has an extremely restricted range, found only in the cloud forests of Alta Verapaz department in central Guatemala. It inhabits montane forests at elevations between 1,400-2,000 meters, where it depends on the persistent moisture and stable temperatures characteristic of cloud forest environments. The species appears to require pristine forest conditions with minimal human disturbance. The primary threat to P. teuchestes is habitat loss through deforestation and agricultural conversion of cloud forests. Guatemala's cloud forests face ongoing pressure from coffee cultivation, cattle ranching, and subsistence agriculture. Climate change poses an additional threat, as rising temperatures may cause cloud formation patterns to shift to higher elevations, potentially eliminating suitable habitat. Limited conservation measures are currently in place. Some populations may occur within protected areas, though enforcement and management effectiveness vary. Research efforts remain minimal due to the species' remote habitat and recent scientific recognition. The outlook for this critically endangered species remains uncertain. Without comprehensive habitat protection and population monitoring, the Alta Verapaz Spikethumb Frog faces significant extinction risk.
