head shape ovoid to subquadrate (Myrmicinae)

Primary tabs

The head is ovoid to subquadrate, but it never has a triangular shape in which the posterior margin is very broad and the lateral margins converge towards a very narrow anterior margin. Used in Antkey to separate all other myrmicine genera from Eurhopalothrix and Strumigenys.
