Natural History:

This species occurs in lowland wet forest. Nests are often in the soil, often in clay banks. Workers recruit to baits on the forest floor and are occasionally collected in Winkler samples.

Longino excavated a nest in a clay bank at La Selva. It had an irregular tumulus of soil around a slit-shaped entrance. A tunnel opened out into a 3-5mm wide gallery extending into the bank. There was a small chamber near the surface and a larger chamber about 15cm deep (horizontal in bank); the nest was not fully excavated and it is unknown if the nest extended deeper. Among the workers were several peculiar intercastes. These look like developmental aberrations. Wilson's revision contains two species, pepo and sphaerica, with this kind of morphology, and it is possible they are similar aberrations.
