Crepidophryne is a small genus of true toads generally placed in the family Bufonidae. The group is known from the highland and montane forests of Costa Rica and Panama, where its members occupy cool, moist habitats at higher elevations. In the literature the genus is often referred to by the common name Cerro Utyum toads. Taxonomists currently recognize three species within the genus.
Characteristics
These toads share features typical of bufonids: relatively stout bodies, dry or warty skin, and terrestrial habits. Crepidophryne species are adapted to montane environments and are most often encountered on the forest floor or near seepages and stream margins. Their diet consists principally of invertebrates, making them predators of forest insects and other small arthropods.
Range and habitat
Crepidophryne occurs in the montane highlands of central America. Populations are documented in the highland regions of Costa Rica and Panama, where cloud forests, elfin woodlands, and páramo-edge habitats provide the cool, humid conditions these toads favor. Because they are restricted to higher elevations, their distributions tend to be patchy and tied to suitable local microclimates.
Ecological role and conservation
- Ecological role: As insectivores, they help regulate invertebrate populations and form part of montane food webs.
- Conservation concerns: Like many montane amphibians, Crepidophryne is vulnerable to habitat loss, climate change, and disease (for example, chytridiomycosis), which can disproportionately affect high-elevation populations.
Because Crepidophryne comprises only a few species with limited ranges, studies of their natural history, population trends, and responses to environmental change are important for local biodiversity conservation and for understanding broader patterns affecting montane amphibians.
