Overview
This species is a mimic of a locally-dominant myrmicine ant, Myrmicaria brunnea.

Names
Scientific source:

Geographic distribution
In the Philippines, Cuernos de Negros Mountains, Dumaguete City, Negros Oriental Province, Negros Island and Mt. Isarog Natural Park, Camarines Sur Province, Luzon Island.

Natural history
This species has been found to nest arboreally in the roots of saprophytic ferns. The Isarog populations are darker in color than the Dumaguete populations, matching the variation in color of the ant being mimicked.

How to encounter
Look for ant gardens in the roots of ferns growing on tree trunks. Beat low vegetation over a white sheet.
