Workers of this species are maroon in colour, and are entirely matte, with no shiny spots.

[1] This species ranges from Guatemala to Colombia,[1][2] and can also be found in Costa Rica.

[1] A. colombica produces visible refuse dumps of spent fungus on the surface.

They deposit the grayish-white pellets at the peak of the mounds, which produces the conical shape.

[3] A colony of A. colombica harvests, on average, 85–470 kg (187–1,036 lb) of plant biomass per year (dry weight), meaning they harvest a leaf area of about 835–4,550 m2 (8,990–48,980 sq ft) annually.
