This species occurs in the Amazon drainage of Peru, from the eastern foothills of the Andes east to the Río Huallaga, in the departaments of Huánuco and San Martín, from 270-1,200m asl.
Habitat and Ecology
This is a diurnal species of lowland and montane tropical moist forest that can be found in both primary and slightly degraded habitat. Eggs are deposited on the ground and the larvae are then transported to streams by the male.
It can be extremely common where it occurs.
There is significant habitat loss within its range due to agricultural activities (mostly coffee plantations).
It is not known from any protected areas, but possibly occurs in Parque Nacional Cordillera Azul and the Bosque de Protección Alto Mayo.
Ameerega bassleri is comprised of a well-supported monophyletic group and shows higher levels of genetic divergence among its populations than those of A. hahneli from the same region (Roberts et al., 2007).
