hairs

gaster with dense pubescence (Nylanderia)

The hairs are rounded and broad at the tip, attenuate at base; spoon shaped (Torre-Bueno). Used in Antkey to identify the genera of Eurhopalothrix, Strumigenys and Strumigenys.

The dorsal surface of the mesosoma may have appressed pilosity, but it lacks erect hairs. Used to distinguish Brachymyrmex JAM-001 from all other Brachymyrmex species in Antkey.

The dorsal surface of the mesosoma has erect hairs that differ distinctly from any appressed pilosity. Used to distinguish all other Monomorium species in Antkey from species in the Monomorium salomonis-group (Monomorium salomonis and Monomorium subopacum).

The cephalic dorsum may have a variety of different hair types, but is never covered by highly modified, flattened, appressed, circular hairs. Used in Antkey to separate all other Strumigenys species from Strumigenys hexamera.
