Resumen
THE INVASIVE NEW ZEALAND MUDSNAIL, POTAMOPYRGUS ANTIPODARUM (GRAY, 1843), WAS IDENTIFY IN CHILE IN 2014 CONSTITUTING, IN TURN, THE FIRST RECORD PERFORMED IN SOUTH AMERICA. UNTIL NOW P. ANTIPODARUM WAS KNOWN BY HAVING TWO VIABLE POPULATIONS IN THE CHOAPA RIVER BASIN, COQUIMBO REGION, NORTHERN CHILE AND TWO IN THE MAIPO RIVER BASIN, METROPOLITANA REGION, CENTRAL CHILE. IN THE SUMMER OF 2016 WE SURVEYED SEVEN WATER BODIES IN THE VALPARAISO REGION, A RELATIVELY LARGE GEOGRAPHIC AREA LOCATED BETWEEN BOTH REGIONS, TO ASSESS THE OCCURRENCE OF THE SPECIES IN CENTRAL CHILE. BASED ON MORPHOLOGICAL ANALYSES AND REPRODUCTIVE FEATURES, WE IDENTIFY THE PRESENCE OF P. ANTIPODARUM IN TWO NEW LOCALITIES. THUS THE DISTRIBUTION OF THIS HIGHLY INVASIVE SNAIL IN CHILE IS EXTENDED TO A MUCH WIDER AREA THAN PREVIOUSLY KNOWN.
