[1][3] The species is only known from its type locality, Madre Selva in the La Convención Province, Cusco, Peru.

The venter (the chest and belly) has a prominent white mark on a black background.

[2] Noblella madreselva inhabits humid montane forests at elevations of 2,330–2,370 m (7,640–7,780 ft) above sea level.

It is largely terrestrial and has been spotted under rocks, logs, and in the leaf litter during the day.

Noblella madreselva is threatened by habitat loss and modification associated with agricultural activities in the region.
