Abstract
Two new carabid beetle species, Pterostichus (Aphaonus) mariamae sp. nov. and Pterostichus (Aphaonus) svetlanae sp. nov., related to an enigmatic mountainous representative of the subgenus Aphaonus, P. (Aphaonus) arcanoides Lorenz, 1998, are described from the Abkhazian midlands (Tsebelda Plateau and Mtsara district). Discriminative features of the new species in the subgenus are briefly discussed.
