DISCUSSION

This is one of several small, nondescript yellow Neivamyrmex species. Because they are rarely encountered, little is known of their habits. Some success has been had locating these minute species using underground baiting, a practice that should be frequently employed. They will likely prove to be subterranean predators of either other ants or of termites.
