In the social structure of Formicidae there is a caste of sexed members in charge of reproduction and a caste of sterile members or worker ants in charge of the rest of the works of the society. Subcastes can ofter be identified within the worker caste. The aim of the present work is to determine if morphological variations allow separate worker caste from Acromyrmex lobicornis Emery 1887 in subcastes. We identified two morphologically distincts subcastes with different functions
