Baetis pentaphlebodes Ujhelyi, 1966, a species new for the Swiss fauna (Ephemeroptera: Baetidae)
In the framework of the MEPT project (red list of Mollusca, Ephemeroptera, Plecoptera, Trichoptera, supported by the Federal Office for Environment), the first author had the opportunity to identify material from the Aare River, containing a single larva belonging to Baetis gr. buceratus (Müller-Liebenau 1969). New samples were made in this locality confirming the presence of Baetis pentaphlebodes Ujhelyi, 1966 in Switzerland. Additional samplings in similar habitats allow the discovery of three new localities. We suspect that this species could be in expansion in Switzerland in the next years.
