The tramp ant Hypoponera punctatissima (Roger), mostly known from the Northern Hemisphere, is reported for the first time from South America in the state of São Paulo, Brazil (22º43'S 44º08'W; 22º24'S 47º49'W), and Reunion Island in the Indian Ocean (20°10'S 55°3'E). H. punctatissima has the widest distribution within Formicidae, being present on many oceanic and continental islands and in all continental regions except Antarctica and the Orient. Reasons for the ecological success of H. punctatissima are discussed.
