Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Amphibia Anura Hylidae

Scientific Name: Hyla nicefori Cochran & Goin, 1970
Common Name(s):
English Colombian Backpack Frog
Cryptobatrachus nicefori Cochran & Goin, 1970
Taxonomic Source(s): Frost, D.R. 2015. Amphibian Species of the World: an Online Reference. Version 6.0. New York, USA. Available at:
Taxonomic Notes: 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).

Population [top]

Population:There is no information on the population status of this species; it is known only from the single type specimen. Surveys in the region of the type locality have not produced any individuals.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:There is no 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.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): 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.

Conservation Actions [top]

Conservation Actions: Additional survey work is urgently required to determine whether or not it still survives in the wild, although further taxonomic research is also needed to ascertain whether or not it is a valid species or not.

Errata [top]

Errata reason: The taxonomic notes have been updated to reflect the transfer of this species from the genus Cryptobatrachus to Hyla. The references for the taxonomic change have been added and other minor typographical errors corrected.
