A slender ant with a high promesonotum, low propodeum, short spines and long gently curved antennal scapes. Aphaenogaster subterranea looks a bit like a Myrmica, at 3-5mm it is a similar size but is slimmer and has short spines. The petiole has a long peduncle rather like a Stenamma.
It is not found in the British mainland but there are occasional records from the Channel Isles.
Common in central and southern Europe.
