Isthmohyla debilis
Isthmohyla debilis is a treefrog in the family Hylidae (order Anura), recorded as Critically Endangered.
Appearance
Males grow to 30 mm (1.2 in) and females to 32 mm (1.3 in) in snout–vent length. The snout is moderately long and acutely rounded. The dorsal color is drab green with small, black flecks, turning white with black flecking on the flanks.
Range and habitat
It occurs in the Atlantic slopes of the Cordillera Central and Cordillera Talamanca in Costa Rica and western Panama as well as on the Pacific slopes in southwestern Panama.
Many of the earlier records come from protected areas (e.g., Fortuna Forest Reserve in Panama).
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.
Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.
In crisis
This species has declined dramatically: it is rare and possibly extinct in Costa Rica, and while observations are still made in Panama, they are decreasing in frequency. Habitat loss caused by agriculture, logging, and human settlement represent additional threats.
Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.
Isthmohyla debilis is Critically Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
