is an island species endemic to Dominica and Guadeloupe in the Lesser Antilles. The syntypes were collected "sifting leaves in forest and among bananas and tree-ferns along the edge of it." (Wheeler, 1913). On Guadeloupe, it occurs from sea level to 800 m elevation, in a variety of forested habitats including wet and seasonal dry forest, mahogany plantation, and cloud forest. All Guadeloupe specimens are from Winkler samples of sifted litter and rotten wood from the forest floor. Dealate queens often occur together with workers in litter samples.
