Dorymyrmex goeldii

This mountain species has been found at some high elevation locales (1700 - 1900 m) but is more common in areas where it has been found in open habitat sites at lower elevation (~ 500 m).

Identification
Cuezzo and Guerrero (2011) - Concolours, light brown. Head longer than wide, with the posterior margin of head strongly convex, scape long (SI: more than 115), long mesosoma, in profile. Characters given in the diagnosis are enough to differentiate this species from all other Dorymyrmex found in Colombia.

Distribution
Geographical distribution of D. goeldii has a strong disjunction in Colombia: some populations are found in the Andean region (Deptartment of Santander and Narino) at high altitude, between 1700 a 1900 m; other colonies, where D. goeldii is more common, prefer open areas of an isolated chain of mountains in the La Macarena National Park; in this area, specimens were collected at 493 m. (Cuezzo and Guerrero 2011)

Distribution based on Regional Taxon Lists
Neotropical Region: Bolivia, Brazil, Colombia.
