The Crematogaster ransonneti-group is revised and three species are recognised, including one new to science. The C. ransonneti-group contains C. cornuta Crawley, 1924; C. keris, new species; and C. ransonneti Mayr, 1868. The species group is distinguished among Asian Crematogaster species by developed propodeal spines and a diamond-shaped petiole. A key to the species of the group based on the worker caste is given. The mouthparts of C. keris, new species, are also described in detail. Morphological characters suggest a close relationship with the C. fraxatrix-group.
