Abstract
The Dorylinae subfamily are dominant invertebrate predators in tropical and subtropical terrestrial ecosystems. The most cryptic army ant genus of the New World is Cheliomyrmex. The only specie recognized until now to the Amazon Brazilian Basin is C. andicola , with record in the state of Acre. We provided the first record of Cheliomyrmex megalonyx to Brazil in the Amazon Basin. This record strongly reinforces the idea that more efforts are needed to reveal the diversity, distribution and biology of such hypogaeic ants.
Highlights
The Dorylinae has currently 18 valid genera, among them the Neotropical army ants, including the genera Eciton Latreille, 1804; Labidus Jurine, 1807; Neivamyrmex Borgmeier, 1894; Nomamyrmex Borgmeier, 1939 and Cheliomyrmex Mayr, 1870
We provided the first records of Cheliomyrmex megalonyx to Brazil in the Amazon Basin
The major worker of Cheliomyrmex megalonyx was collected in the state of Rondônia while the minor was found in the state of Amazonas
