Psychrophrynella quimsacruzis is known from Choquetanga and Mina Caracoles (16 52' 39" S, 67 18' 23" W, 3660 masl) and from the junction of the roads to Quime and Choquetanga (17 00' 02" S, 67 16' 49" W, 3730 masl), Province of Inquisivi, Department of La Paz, Bolivia. The two localities are separated by an airline distance of 13.9 km, and lie in the northeastern versant of the main massif of the Cordillera de Quimsa Cruz (De la Riva, 2007).
Habitat and Ecology
The species is found in humid paramo habitats. Individuals can be found under stones by day. Gravid females were found to contain numerous, large, unpigmented eggs. Other anurans at the type locality are Telmatobius bolivianus and Gastrotheca marsupiata (De la Riva, 2007).
It seems that there are two different populations of this species; however, it is not known whether these populations are conspecific with each other (I. De la Riva, pers. comm. 2008).
Mining activities can be a potential threat to the species. In addition, a restricted geographic distribution and the predicted effects of climate change (e.g. drying up of regions) are considered to pose serious threats to the species (I. De la Riva, pers. comm. 2008).
No conservation measures are known for this species.
Red List Status
Listed as Vulnerable in view of its extent of occurrence of less than 20,000 km2, area of occupancy of less than 2,000 km2, with all individuals in fewer than ten locations, and a projected decline in the extent and quality of its habitat due to mining and climate change.
Psychrophrynella quimsacruzis is distinguished from other similar species by a combination of colour patterns and morphological features (De la Riva, 2007).
