Heterogeomys dariensis ssp. thaeleri
|Scientific Name:||Heterogeomys dariensis ssp. thaeleri|
|Species Authority:||(Alberico, 1990)|
Orthogeomys thaeleri Alberico, 1990
|Taxonomic Source(s):||Russell, R. J. 1968. Evolution and classifi cation of the pocket gophers of the subfamily Geomyinae. Univ. Kansas Publ., Mus. Nat. Hist. 16: 473– 579.|
|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.
|Red List Category & Criteria:||Least Concern ver 3.1|

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.
|Previously published Red List assessments:|
|Range Description:||This species occurs in Serranía de Baudó (extreme north-west Colombia) (Patton 2005). It has an altitudinal range of 100 to 500 m (Alberico et al. 2000).|

|Population:||It is locally abundant, but populations are patchily distributed (Emmons and Feer 1997).|
|Current Population Trend:||Stable|
|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.|
|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:||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.).|
