Abstract The taxonomy and identification of mayflies of the Baetis vernus group (Ephemeroptera: Baetidae) represents a major challenge in both Europe and North America. The recent description of B. jaervii Savolainen from Finland, a species taxonomically close to the Palaearctic taxon Baetis macani Kimmins and the Nearctic B. bundyae Lehmkuhl, called for clarification of the status and distribution of these species in northernmost Europe. We generated mtDNA COI sequences for establishing the identity of the collected samples. Based on these data we conclude that B. bundyae does occur in northeastern Finland in sympatry with B. macani . Accordingly, this taxon shows a highly interesting distributional pattern across the Nearctic and western Palaearctic regions.
