Natural History

The type series of this species is from La Selva Biological Station. Longino collected from a nest in the Arboretum, a small park-like clearing surrounded by mature rainforest. Galleries were discovered in clay soil about 10cm deep. There were workers and abundant adult males. The galleries were penetrated by fine plant roots on which were clustered many small, white, globose Coccoidea.
