Scientific Name: Heterogeomys dariensis ssp. thaeleri (Alberico, 1990)
Parent Species:
Common Name(s):
English Thaeler's Pocket Gopher
Orthogeomys thaeleri Alberico, 1990
Taxonomic Source(s): Sudman, P.D. and Hafner, M.S. 1992. Phylogenetic relationships among Middle American pocket gophers (genus Orthogeomys) based on mitochondrial DNA sequences. Molecular Phylogenetics and Evolution 1: 17-25.
Taxonomic Notes: This species shows a low genetic divergence from O. dariensis (see Sudman and Hafner 1992), and is treated as a subspecies of that taxon (Hafner 2015).

This is an amended assessment to take into account the taxonomic change.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2008-07-01
Assessor(s): Anderson, R.P., Gómez-Laverde, M., Samudio, R. & McCarthy, T.
Reviewer(s): McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)
Listed as Least Concern since, although its extent of occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat that does not appear to be under threat, has a presumed large population, and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Population [top]

Population:It is locally abundant, but populations are patchily distributed (Emmons and Feer 1997).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It occupies open habitats with well-drained soils (Emmons and Feer 1997). It also occurs in tropical rainforest, mainly in lowlands. It is probably both diurnal and nocturnal, fossorial, and solitary. It is herbivorous and feeds on underground plant parts, such as tubers and stems, and on above ground parts pulled down from below. The presence of pocket gophers is shown by their shallow foraging tunnels, which appear as low humps snaking between damaged plants.

Threats [top]

Major Threat(s): There are no known major threats to this species; it occurs in a remote area (R. P. Anderson pers. comm.).

Conservation Actions [top]

Conservation Actions: This species is probably found in one protected area in Colombia, Cuena Quebrada Mutata Forest Reserve. It is not known from any other protected areas (R. P. Anderson pers. comm.).
