This key is based on: Xu, Z. 2003. A systematic study on Chinese species of the ant genus Oligomyrmex Mayr. Acta Zootaxonomica Sinica. 28:310-322. PDF. At the time of this study, the genus Carebara was not consolidated as it is today and its species were divided between a number of genera. This key was made for the group of Carebara species that were included in the genus Oligomyrmex hence does not include all the species of Carebara currently known from China.
