Syllophopsis  sechellensis  (Emery)  (formerly  Monomorium  sechellense) (Hymenoptera: Formicidae) is a small, inconspicuous ant species native to the Old-World tropics. Syllophopsis sechellensis is widespread in Asia and Australia, and on islands the Indian, Pacific, and Atlantic Oceans. In the New  World,  all  published  records  come  from  West  Indian  islands.  Here,  I report the first records of S. sechellensis from North America: from four sites in Miami-Dade and Broward counties, Florida, more than 1500 km from the closest records in the West Indies. The ants of Florida have been well-studied in the past, so S. sechellensis appears to be a recent arrival.
