Noblella madreselva occurs in an area measuring just 10km².
This species is known only from its type locality (the place it was first found), N. madreselva is likely to be restricted to areas of upper watersheds of its type locality and adjacent valleys.
The Craugastoridae family which this species belongs diverged from its closest family, between 31 and 59 million years ago, before the major Andean uplift!
The population is thought to be decreasing due to ongoing decline in the quality and amount of habitat. In 2011 surveys of 6 sites showed that N. madreselva was only present at one – where it was the most common amphibian there.
The main threat to this species is habitat loss due to increased agriculture in the area. N. madreselva does not occur in any protected areas, further research into the distribution, population and natural history of this species is required.
- Order: Anura
- Family: Craugastoridae
- Population: Unknown

This species has been found in the town of Madre Selva, District of Santa Ana, province of La Convención, Cusco Region, Peru, between 2,330–2,370m above sea level in the high-elevation forests in the Andes.
Habitat and Ecology
This species occurs in humid montane forests. N. madreselva is mainly terrestrial living under rocks, logs, and in the leaf litter during the day. Reproduction is assumed to occur by direct development as for other species within the Noblella genus.
