Identification
For the differences from Aphaenogaster groehni, see there. A. ribbeckei differs well from other previously described Aphaenogaster species from the Late Eocene European ambers primarily by the much more slender mesosoma and waist, in particular, ML/MH 3.7 vs. < 3.0, PL/PW 3.2 vs. < 2.2. By the shape of promesonotum A. ribbeckei resembles Aphaenogaster sommerfeldti, but differs by this feature from other amber species. In addition, it differs from Aphaenogaster oligocenica by the longer and pointed propodeal spines, and from Aphaenogaster antiqua — by the longer scape and funicular segments.
Distribution
This taxon was described from Baltic amber, Baltic Sea region, Europe (Bartonian, Middle to Late Eocene).
