Odontomachus ferminae

This ant is locally abundant at lower elevations of Mt. Guiting-Guiting, Romblon Province, Philippines, specifically the area around "Camp 1", at about 300 meters above mean sea level. They can be seen foraging along the trail to Camp 1 and in the leaf litter and open ground in the Camp. They are evidently tolerant to some degree of disturbance since the area is a semi-permanent trail and campsite.
