mandibles linear
mandibles linear
The mandibles are long and straight, not triangular. They lack distinct teeth on their inner margins, but can be armed with an apical fork. Used in Antkey to separate Anochetus, Leptogenys and Odontomachus from other Ponerine genera. Anochetus and Odontomachus are referred to as trapjaw ants.
1 preapical tooth
1 preapical tooth
There is one tooth on the inner margin proximal to the apical fork. Used in Antkey to separate all other Strumigenys from Strumigenys rogeri.
2 preapical teeth
2 preapical teeth
There are two teeth on the inner margin proximal to the apical fork. Used in Antkey to separate Strumigenys rogeri from all other Strumigenys.
