From the IUCN Red List Species Account:


Range Description

This species is known from the humid lowlands of the Atlantic versant in southern Costa Rica and adjacent north-western Panama, from 170-440 m asl (Savage 2002). Its range, taken as a proxy for extent of occurrence (EOO), is estimated at 1,336 km

Habitat and Ecology

The few known specimens have been collected on low vegetation (approximately 3 m above ground) within humid lowland forest. The species may be associated with headwater streams (Savage 2002). Larval development is presumed to take place in these streams.


It is a rare species known only from three specimens.

Population Trend


Major Threats

The major threat to the species is general habitat loss due to deforestation for smallholder farming activities, logging, and human settlement. Chytridiomycosis is also a potential threat to this species.

Conservation Actions

It has not been recorded from any protected areas in the lowlands, but has been recorded from private reserves in Monteverde. The lowland forest habitat of this species is in urgent need of protection. Further research is needed to determine the current population status of this species, and whether it is at risk of infection with chytrid.

Taxonomic Notes

Further taxonomic work is needed to finally determine whether Duellmanohyla lythrodes is a synonym of Duellmanohyla rufioculis (Federico BolaƱos pers. comm. 2007).
