1-7 (facing page). Pictorial key to ant subfamilies in Kansas.
It is unlikely you will encounter subfamily Ecitoninae.
Some small Myrmicinae may be confused with this subfamily
as they also have small eyes (for example, Solenopsis).
However, these have an antennal "club" formed
an enlargement of, at least, the ultimate and penultimate
segments. Ecitoniane lack this antennal club. All Figures
represent lateral views of ants (unless noted) with sculpture,
pilosity, and majority of legs omitted.
