This species is known from two localities within Paramillo National Park in Antioquia Department, on the northern slope of the western Andes, Colombia, at 1,500 m asl. Its extent of occurrence (EOO) is 64 km2.
Habitat and Ecology
Both of the known localities are within primary forest. The species was found in rocky areas with sparse vegetation near the headwaters of the Rio San Jorge (Rivero and Serna 1993). Although there is limited ecological information, it is expected to breed in streams by larval development, as with other congeners.
This species is known only from 10 specimens, and has not been collected since its description in 1993. There has been no recent survey work within its range, as the area where it occurs is very difficult to access due to civil unrest. Without clarification on the threats to this species and the lack of recent surveys, the population trend is unknown.
Its entire range is within protected areas, but it is unclear whether there are any threats that may be affecting the species. In 2004 it was reported that the major threat was likely to be chytridiomycosis leading to a catastrophic population decline as has occurred in many other montane species of Atelopus, however there is no further information on this threat (Colombia Red List Assessment Workshop August 2016).
This species occurs in Paramillos National Park.
Further research into the species' range, ecological requirements, and population status is needed, in particular to determine if it occurs outside its current known range.
Red List Status
Data Deficient (DD)
Listed as Data Deficient as this species is known only from two localities in the northern portion of the Cordillera Central in Colombia, and has not been collected since its original description in 1993. While chytridiomycosis has caused major declines in other Atelopus species, and may have resulted in the disappearance of this species, there is no current data to support this as there have not been any recent surveys in the area due to civil unrest. In addition, while the entire known distribution is within a national park, the threats affecting the species are unknown.
