Strumigenys louisianae
Roger, 1863
louisianae-group Pygmy Snapping Ants
Strumigenys louisianae is a tiny predatory in the Formicidae. It possesses the broadest geographic distribution of any New World Strumigenys , ranging from Argentina to North Carolina. The species inhabits diverse across this range, making it difficult to determine where it is native versus introduced. Genetic studies are needed to clarify its biogeographic origins.

Habitat
Found in a wide diversity of across its extensive range, from tropical forests to temperate areas. Specific microhabitat preferences within these environments have not been documented.
Distribution
Largely continuous range from Argentina to North Carolina, with possible extensions to Virginia and Illinois. Present on most major West Indian islands, the Galápagos Islands, Cocos Island, and in Arizona. Isolated occur in these peripheral locations, some of which may represent introduced rather than native occurrences.
Diet
Feeds on soil arthropods.
Ecological Role
Predatory that preys on soil arthropods.

Biogeographic uncertainty
The occurrence of S. louisianae throughout such a broad range in diverse makes it difficult to distinguish native from introduced . Some isolated populations, particularly on oceanic islands (Galápagos, Cocos) and in Arizona, may be introductions rather than native occurrences.
Research needs
Genetic analyses are required to determine where S. louisianae is native and where it represents introduced .
