For the first time, It was recorded that the dolichoderine ant genus Gracilidris and its sole species, G. pombero were found in the Colombia Amazon basin[5]
The single existing fossil in Dominican amber makes the genus a Lazarus taxon. The only known extant species, Gracilidris pombero, nests in small colonies in the soil. These ants have been described only very recently and little is known about them.
