This widely distributed species is a sand specialist, being found almost exclusively in deep sand deposits.


The only member of the neogagates group that is concolorous yellowish red. The entire ant, including the appendages, is covered with bristly, white hairs, except for the scape, which is without erect hairs. The surfaces are shiny and the anterior border of the clypeus is concave, nearly notched. The male is unusual as it has a shiny head and mesosoma.
