Presence of exotic species of the wild bee genus <i>Hylaeus</i> (Hymenoptera: Colletidae) in the Canary Islands revealed by molecular and citizen science

In this study, we update the knowledge about wild bees of genus Hylaeus in Canary Islands and discuss possible effect on phenology exotic species endemic ones. Our records come both from entomological samplings citizen science through photos registered social networks. An additional molecular approach was performed to confirm correct identification analyze their geographic origin. Two new species, (Paraprosopis) pictipes Nylander, 1852 Tenerife (Spatulariella) punctatus (Brullé, 1832) Gran Canaria have been detected. addition, provide sulphuripes (Gribodo, 1894) Canaria. All three show a flight season extending late spring early winter. Most observations were made anthropized areas, visiting native plants. Exotic localized larger islands archipelago where maritime traffic is higher, being most likely route entry. Molecular data suggest two independent arrivals H. Iberian Peninsula, while puntactus would arrived central Europe. There little overlap with habitat so there does not seem be potentially significant negative them.
