Identification

Hosoishi and Ogata (2016) - Examination of syntype workers in MCSN and MHNG reveals that C. crassicornis does not belong to the subgenus Orthocrema. Although this species has two-segmented antennal club, characteristic features include: anterolateral margins of clypeus protruded anteriorly; petiole without node-like process posteriorly in lateral view; postpetiole bilobed with longitudinal median sulcus. These features are characteristic of the subgenus Crematogaster and we consider C. crassicornis to be referred to that subgenus.
