Aphaenogaster jolantae

A nest of this species was located in a crevice inside a shallow cavern, near the middle of a 3 m high wall of a gorge on the famous tourist route Epta Piges (Seven Springs). Workers were foraging on the inner wall of the cavern at a distance of 1 m from the entrance to the nest. A couple of the foragers were carrying remains of moths collected from a nearby spider web. More workers were found in a hollow trunk of a huge Platanus orientalis tree. A large entrance to the hollow tree was located about 70 cm above the ground and led to a hollow trunk that could accommodate two standing people standing. The interior walls of the tree were charred; the entrance to the nest was probably on the roof of the hollow, where a few foraging workers were collected. (Borowiec and Salata 2014)

Identification
Borowiec and Salata (2014) - A member of the Aphaenogaster cecconii group. Within this group, Aphaenogaster jolantae, Aphaenogaster olympica and Aphaenogaster equestris are together easily distinguished from the other three species in the group by the head lacking a narrowed neck with flared collar. Aphaenogaster equestris differs in having the body mostly rusty-yellow and the sculpture of the head stronger, with the head surface partly dull. Aphaenogaster olympica is very similar and differs in subtle morphometric and sculptural characters described in the key.

Distribution
Greece, Dodecanese, Rhodes Island.

Distribution based on Regional Taxon Lists
Palaearctic Region: Greece.

Biology
This species clearly has a preference for wet, shady areas. Non type workers have been found: on the damp wall of a shallow cave, on the damp wall of a deep gorge and in crevices of rocks in a shady forest (Salata and Borowiec 2014).
