Abstract:
Published geographical records of tramp species elsewhere, Anoplolepis gracilipes (F. Smith, 1857), Solenopsis
geminata (Fabricius, 1804) and Trichomyrmex destructor (Jerdon, 1851), medically important Odontomachus simillimus
F. Smith, 1858 and Tetraponera rufonigra (Jerdon, 1851), and mainly, a predator of insect pests, Oecophylla smaragdina (Fabricius, 1775) are listed and positioned on a Sri Lanka map for the first time, using Global Positioning System and an ArcGIS software. Future surveys are essentially required to fill the gaps due to less information in several districts.
