The nest entrance was located in a gap in a concrete culvert 2 m across, by a road, at the height of about 1.70 m above the ground. Foraging workers were observed mainly within 1 m from the entrance to the nest, but two workers were caught 2 m from the nest, low above the ground in a tight dark place. (Borowiec and Salata 2014)

Identification

Borowiec and Salata (2014) - A member of the Aphaenogaster cecconii group. Within this group, Aphaenogaster lykiaensis, Aphaenogaster cecconii, and Aphaenogaster phillipsi have the head strongly narrowed posteriorly to a neck with a flared collar. Aphaenogaster phillipsi distinctly differs in the body being almost uniformly yellow to rusty yellow. Aphaenogaster cecconii at first glance looks the most similar but differs in being dark brown to black with a whitish to yellow-white spot at the base of the first abdominal tergite, and with stronger sculpture on the frons.
