(Forel, 1893)

West Indian Crazy Ant

Nylanderia steinheili is an in the Nearctic region, originally described by Forel in 1893 under the Prenolepis. It is one of at least five Nylanderia species introduced to North America from tropical regions. The species is known from the West Indies and has been recorded in the Galápagos Islands and parts of South America. Its introduced status in the Nearctic suggests potential for ecological impact, though specific biological details remain poorly documented compared to like the tawny crazy ant (Nylanderia fulva).
