Habitat:
It occurs in forest and along forest edges or openings, retreating by day into bromeliads or under moss and rocks. It has not been recorded outside forest habitats. Eggs are laid in bromeliads, and it breeds by direct development.

Range:
This species has a restricted range in the interior uplands in Puerto Rico. Historically, it occurred at elevations between 39–1,045 m asl, but is now only found between 654–1,049 m asl, suggesting a significant range contraction of the lower elevational limit (Campos-Cerqueira and Aide 2017). It has been extirpated from sites in the Cordillera Central and Carite State Forest, and it is now only thought to occur at high-elevations of El Yunque National Forest (Puerto Rico Red List Assessment Workshop 2020) in a single threat defined location, and with an extent of occurrence (EOO) of 99 km2.

Conservation:
Conservation Actions In-Place
Historically this species occurred in a few protected areas, Carite State Forest, Toro Negro State Forest, Maricao State Forest and Los Picachos State Forest; however, it is now only thought to occur at high-elevations of El Yunque National Forest (Puerto Rico Red List Assessment Workshop 2020).

Conservation Needed
Economic development should not be granted priority over currently federally protected natural resource areas in Puerto Rico and the protected status of such lands should be maintained. Buffer zones should be established to help ensure that land use activities do not threaten the integrity of the core protected areas. In view of the negative effects of anthropogenic climate change on this species and its habitat, national and global policies are needed to curb the use of and reliance on fossil fuels. Community education and awareness programmes aimed to generate knowledge of and appreciation for Puerto Rico's endemic amphibians are recommended (Puerto Rico Red List Assessment Workshop 2020).

Research Needed
A  range-wide assessment of all historical sites is needed, and is of particular importance after hurricanes. Careful population monitoring is required. More research is needed to better understand the species-specific response to the effects of climate change (Puerto Rico Red List Assessment Workshop 2020).
