Identification

Ionescu-Hirsch (2009) - This is a small dimorphic species with a phragmotic “soldier”. The major worker has a cylindrical, abruptly truncate head. The minor worker has a rounded head and can be recognized by the straight frontal carina, antennal insertion close to the middle of the frontal carina, propodeum dorsum distinctly concave in lateral view, and by the petiole scale with acute summit in lateral view and indented dorsum in front view.
