This species is known only from the type locality of La Salina, Casanare Department, Colombia, at 1,450 m asl. Its extent of occurrence (EOO) is 75 km2.
Habitat and Ecology
There is little information on the habitat and ecology of this species. However, like other members of its genus, it is probably associated with streams and waterfalls in montane forest. The eggs are carried on the back of the female, where they develop directly without a larval stage.
This species is only known from the holotype that was collected in the 1940s. Surveys prior to 2004 in the region of the type locality did not produced any individuals. There have been no surveys between 2004 and this reassessment at the type locality, due to ongoing armed conflict which has recently ceased in the area. There are plans to visit the type locality and near areas in the second half of 2017 (J. Carvajal-Cogollo and F.L. Meza-Joya pers. comm. March 2017).
There is no information about threats affecting the species. However, the region where this species occurs has been severely affected by mining for salt production, and all possible suitable remaining habitat for this taxon has been destroyed at the type locality. But there is suitable habitat north and south of the type locality (J. Carvajal-Cogollo pers. comm. March 2017).
This species has not been recorded in any protected areas.
Conservation recommendations are pending following future surveys and once the population status of the species and habitat requirements are determined (F.L. Meza-Joya pers. comm. March 2017).
Additional survey work is urgently required to determine whether or not it still survives in the wild. More information is needed on this species' distribution, population status, ecology, and threats. Further taxonomic research is also needed to ascertain the true genus that it should be assigned to [either Hyloscirtus or Cryptobatrachus] (J. Carvajal-Cogollo pers. comm. 2017).
Red List Status
Data Deficient (DD)
Listed as Data Deficient because its distribution, abundance, trend, and threats are too poorly known to allow the species to be placed in another category.
Many researchers doubt the validity of this species. The single specimen might belong in the genus Hyla.
Infante-Rivero et al. (2009) suggested that this species, known only from the holotype, is not a member of Cryptobatrachus (the genus it was originally assessed under), but a hyline unassigned to genus, although possibly in Hyloscirtus (Frost 2015). It has been placed under "Hyla" for the interim (Frost 2015).
