BANEGAS, Bárbara P. et al. First record of Cloeon dípterum (L.) (Ephemeroptera: Baetidae) in Buenos Aires, Argentina. Rev. Soc. Entomol. Argent. [online]. 2020, vol.79, n.3, pp.1-10. ISSN 0373-5680.  http://dx.doi.org/https://doi.org/10.25085/rsea.790304.

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