Crematogaster crassicornis Emery, 1893: 265 , pl. 2, figs 4, 5;

syntype workers, Manila, Philippines (M. E. Simon) ( MCSN, MHNG, examined).

Crematogaster crassicornis ; Emery, 1922: 132 [Combination in C. ( Orthocrema )].

Crematogaster crassicornis ; Blaimer, 2012c: 55 [Combination in C. ( Orthocrema )].

Comments: 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.
