Abstract. Indochinese species of the genus Crematogaster Lund, 1831 subgenus
Physocrema Forel, 1912 are reviewed. Four species are recognised in the region. Two
taxa formerly treated as subspecies of difformis, C. (P.) physothorax Emery, 1889 and
C. (P.) sewardi Forel, 1901, are raised to species level. An identification key to species
in the region is presented.
