Aphaenogaster tennesseensis

This species is presumed to be a temporary parasite in ground nests of other species of Aphaenogaster, including Aphaenogaster fulva, Aphaenogaster picea and Aphaenogaster rudis (Smith, 1979). Workers forage on trees and nest in rotting wood.

The queens are very distinctive looking and are almost entirely smooth, lacking any obvious sculpture, and have long blunt tipped propodeal spines.
