Overbeckia is a genus of ants in the subfamilyFormicinae originally containing only the single speciesOverbeckia subclavata.[1] Although the genus has been known over 100 years only from Singapore, where its nests were found in hollow branches of bamboo and other plants,[2] a revision study by Klimes and coll. in 2022[3] showed that these ants occur across tropical SA Asia to Australasia and re-described the genus, Overbeckia subclavata.[1] and described two new species, Overbeckia jambiensis, and Overbeckia papuana.[3] The study also showed that more recent findings of Overbeckia in Australia [4] are likely O. papuana, based on morphology.
