Mannophryne leonardoi is known from its type locality [caserío El Toyano, Parroquia Pozuelos, Municipio Sotillo, Estado Anzoátegui, Venezuela (10 07´30.7" N; 64 29´ 35.7" W)] and the areas within the Turimiquire Massif (ca 540 000 ha), in NE Venezuela. The species can be found throughout a wide altitudinal gradient, from a few metres above sea level to 1650 masl (Manzanilla et al., 2005).
Habitat and Ecology
The species lives in montane forests and forests at the foothill of the Turimiquire massif. It is often found next to streams, and males sit on higher elevation objects, from where they call. Females are often dispersed around the area (Manzanilla et al., 2005).
This used to be a common species, but recent surveys suggest a dramatic population decline, potentially associated to the use of agrochemicals (see Manzanilla et al., 2005).
Part of the area is being afflicted by urban development, agriculture and building of roads (Manzanilla et al., 2005).
The species occurs within several protected areas (area protectora del Macizo de Turimiquire, Mochima National Park and Cueva del Guacharo National Park) (Manzanilla et al., 2005).
Mannophryne leonardoi can be dintinguished from other similar species by a combination of morphological characters (Manzanilla et al., 2005).
