Identification
This species differs well from all previously described Aphaenogaster species from the Late Eocene European ambers primarily by the shape of the head, which is gradually narrowed posteriorly and without marked occipital corners, a significantly longer scape, which is about 1.3 times as long as head and exceeds occipital margin by about 1/3 of its length, and longer funicular segments. In addition, A. groehni differs from Aphaenogaster sommerfeldti by the shape of the mesonotal dorsum, which does not raise over pronotal dorsum, from Aphaenogaster oligocenica — in the longer and pointed propodeal spines.
Distribution
This taxon was described from Baltic amber, Baltic Sea region, Europe (Priabonian, Late Eocene).
