The mandibles have only a single tooth at the tip. Length of the worker ant is about 2 mm. The antenna has 9 segments, the last segment being greatly enlarged forming a club. The second segment of the gaster is strongly arched so that the sting faces forward. Coloration is uniformly rusty red-brown.
Colonies are small with fewer than 50 workers, so nests can easily be overlooked. Workers feign death when disturbed.
