Cloeon dipterum (L.) (Ephemeroptera: Baetidae) is widely distributed intemperate areas of Eurasia, whereas, in North America, it is restricted to three states of theUSA and Canada, and, in South America to Chile. To confirm our hypothesis that C. dipterumhas been recently introduced in Argentina, the aim of the present study was to identify thespecies based on molecular analyses and morphological features. To this end, nymphs werecollected from three artificial habitats located in different localities of Buenos Aires provinceand two tributary streams of the Luján River, northeast of Buenos Aires, Argentina. Nymphswere all identified as belonging to C. dipterum thus confirming the presence of the speciesin Argentina. The distribution of C. dipterum in Buenos Aires, together with its absence frompreviously sampled sites, would indicate that the individuals recorded are introduced andalready well established in the study area.
