Strumigenys louisianae Roger, 1863

Distribution. USA to Argentina; widespread in eastern USA from Florida to New York and west to Missouri; in western USA occurs in Oklahoma and Texas.

Comments. Strumigenys louisianae has one of the largest continuous native ranges of any Strumigenys species, from South America through Mexico and into the USA. In the USA, it is the most commonly encountered long mandible trap-jaw species north of Florida (Deyrup & Cover 2009; Booher unpublished data). It was first recorded in Oklahoma with a collection near the city of McCurtain in the southwestern Ozark Mountains (Wheeler & Wheeler 1989). All specimens I have examined from Arizona were mistakenly identified and corrected to be S. mixta .
