Description
Creighton (1950) was the first to consider these forms and reduced the number of valid taxa from four to two, treating “alabamensis” as a synonym of A. treatae and “oklahomensis” as a synonym of A. treatae pluteicornis. He separated A. treatae from A. treatae pluteicornis based on differences in head shape (longer and narrower and with the posterior margin narrower and flatter in A. pluteicornis) and sculpturing (longitudinal rugae present on the front of the head in A. treatae, only rarely present in A. pluteicornis).

Distribution
Aphaenogaster treatae occurs from Maine south to the Gulf Coast (northern Florida) and west to eastern Texas, Oklahoma and north to Indiana and Illinois. Note that in the eastern states, A. treatae nests in well-drained, often sandy soils in open habitats. Nests are generally inconspicuous and are commonly found under grass clumps. In eastern Texas, the second author found the species in open, sometimes recently burned pine-oak forests and in small gaps in such forests. Of five collections, two were nests in soil, but three colonies were in red rotten pine branches or logs on the soil surface.
