This is a tool to identify single workers of ants of the Tetramorium caespitum/impurum complex:
First, click "Manual" to view the character definitions; second, acquire the morphometric data for your specimen; third, click "data entry" and enter the character values; fourth, click "identify". For interpretation of the returned probability values of species memberships, see "Manual"
