mandibles very straight with an abrupt attenuation near insertion of preapical tooth (Strumigenys)
mandibles armed with denticles

The mandibles are linear and armed anteriorly with small denticles. Used in Antkey to separate Strumigenys species.
mandibles long and linear with 7 teeth

The mandible long and linear with seven teeth (one apical, one sub-apical, and five basal). Used in Antkey to separate Amblyopone zwaluwenburgi from Prionopelta species.
mandibles lacking abrupt attenuation

The mandibles are evenly curved, lacking abrupt attenuation near insertion of preapical tooth. Used in Antkey to separate Strumigenys godeffroyi and Strumigenys lewisi from Strumigenys lanuginosa.

The mandibles are very straight with an abrupt attenuation near insertion of preapical tooth. Used in Antkey to separate Strumigenys lanuginosa from Strumigenys godeffroyi and Strumigenys lewisi.
mandibles triangular

The mandibles are triangular. Used in Antkey to separate Strumigenys species.
mandibles tridentate

The mandible somewhat linear and armed with three apical teeth. Used in Antkey to separate Amblyopone from Prionopelta.
apical fork present

The teeth at the apex of the mandibles form a vertically arranged fork of two or three enlarged, frequently spiniform teeth. Used in Antkey to separate Odontomachus from Leptogenys.
