Exploring the hidden riches: Recent remarkable faunistic records and range extensions in the bee fauna of Italy (Hymenoptera, Apoidea, Anthophila).

BACKGROUND

The area sourrounding the Mediterranean basin is recognised as a major biodiversity hotspot for bees, and Italy is amongst the European countries with the highest bee species richness. Detailed knowledge of bee distribution is crucial for understanding bee biology and designing tailored conservation strategies, but is still insufficient in southern European countries, especially in Italy.

NEW INFORMATION

We report recent finds of 48 bee species that yield significant novelties for the Italian bee fauna. Eight species, namely Stöckhert, Pérez, Foerster, Strand, Thomson, Pérez, auct. nec Zanden and Eversmann are reported as new for Italy. In addition, Smith, Lepeletier, Pérez, Vachal, Spinola and Fabricius are newly recorded from mainland Italy, Pérez from Sardegna and Kirby from Sicilia. We also report significant range extensions for other bee species and recent records of species that had long gone unrecorded in Italy. The combination of morphology and DNA barcoding provided reliable identifications even for the most challenging specimens. As several of our records come from areas neglected by bee experts in the past, this study stands out as a key indicator of a bee faunistic richness still awaiting discovery and hopefully it will stimulate the interest of taxonomists and stakeholders in pursuing bee research in Italy in the near future.
