Pristimantis carlossanchezi is known from localities ranging from the departments of Santander (northern section) to Boyacá (south-western section), Colombia. It has been recorded for elevations ranging from 2400-2550 masl (Arroyo, 2007).
Habitat and Ecology
The species is more frequently observed in cloud forest above 2400 masl, particularly in secondary forest (S. Arroyo, pers. comm. 2008). Individuals are found on leaves at heights 1.5 to 2.0 m above the ground and are nocturnal. Pristimantis carlossanchezi was not heard, male calling activity was not recorded (Arroyo, 2007).
It is considered to be a rare species (Arroyo, 2007).
Given that the species was collected in regenerating secondary forest, perhaps deforestation could be a possible threat (S. Arroyo, pers. comm. 2008).
In the course of three studies the species was collected at two different sites, both of which are in protected areas [one is in a Reserve projected to become a Natural Park, and the other one is in an area that has been declared as a Sactuary](S. Arroyo, pers. comm. 2008).
Pristimantis carlossanchezi is diagnosed by a combination of morphological characters and colour patterns (Arroyo, 2007).
