Geographic distribution of Leptogenys elongata (Buckley) and Leptogenys manni Wheeler (Hymenoptera, Formicidae, Ponerinae)

Leptogenys elongata and Leptogenys manni (Hymenoptera, Formicidae, Ponerinae), the only described Leptogenys known from the continental US, were recently included on a list of exotic ants established in North America. To evaluate this possibility, I compiled and mapped published and unpublished specimen records of L. elongata and L. manni. Leptogenys elongata records have an essentially continuous distribution through central and eastern Texas (65 counties), southern Oklahoma (one county), and western Louisiana (eight parishes), south through much of Mexico (nine states), plus one questionable record from Colorado and one almost certainly erroneous record from the District of Columbia. Leptogenys manni records are known from much of Florida (22 counties), plus one isolated record from Georgia that needs corroboration. I found no credible evidence that L. elongata or L. manni have established populations anywhere beyond their native ranges
