Psychrophrynella ankohuma is known from the type locality, Cooco (15 47' 14.4" S, 68 26' 55.9" W, 3540 masl), and a nearby locality, Ankho Uma (Ancoma; 15 44' 33.0" S, 68 29' 22.8" W, 3690 masl), Province of Larecaja, Department of La Paz, Bolivia. These localities are 6.6 km (airline) apart, without discontinuity in habitat (humid paramo) (De la Riva, 2007). It is believed to be restricted to one valley (I. De la Riva, pers. comm. 2008).
Habitat and Ecology
The species occurs in humid paramo. Individuals can be found during the day under stones, and males can be heard calling at night (De la Riva, 2007). It is presumed to breed by direct development.
The species is abundant within its known distribution (De la Riva, 2007).
The predicted effects of climate change (e.g. drying up of regions) are considered to pose a serious threat to this species, in addition to its restricted distribution (I. De la Riva, pers. comm. 2008).
No conservation measures are known for this species.
Psychrophrynella ankohuma is distinguished from other similar species by a combination of colour patterns and morphological features (De la Riva, 2007).
