This is the first formal report of members of the family Caecidae in Argentine waters. Caecum striatum de Folin, 1868, C. strigosum de Folin, 1868, and C. achirona (de Folin, 1867) are re-described from shallow waters off Piedras Coloradas (40º53?4.83?? S, 65º7?34.53?? W), Río Negro Province, Argentina. This is the farthest south record of these species which were previously recorded from USA, Bahamas, Panama, Brazil, and Uruguay. The authors also make observations about the different ontogenetic stages of the studied species. Scanning electron microscope illustrations of radula and operculum are provided for the first time.
